The sum of 5500 mm, 720 cm, 90 dm, and 20 dam can be expressed in meters as 58.2 meters. To convert the given measurements to a common unit, we need to convert each unit to meters and then add them together.

1 meter is equal to 1000 millimeters (mm), 100 centimeters (cm), 10 decimeters (dm), and 0.1 decameters (dam).

Converting the given measurements to meters:

5500 mm = 5500/1000 = 5.5 meters

720 cm = 720/100 = 7.2 meters

90 dm = 90/10 = 9 meters

20 dam = 20 * 0.1 = 2 meters

Now, we can add these converted measurements together:

5.5 meters + 7.2 meters + 9 meters + 2 meters = 23.7 meters

Therefore, the sum of 5500 mm, 720 cm, 90 dm, and 20 dam in meters is 23.7 meters.

Thus, the given expression has been simplified.

1. Lisa should work with her lender to sell her property as a short sale, considering the significant decrease in its value and her inability to make loan payments.

2. The counteroffer made by the owner has been rescinded, so there is no contract in place.

3. Wendy is required to complete 45 hours of post-license education before her first license renewal date.

4. Rachel should encourage her client to obtain a pre-approval letter from a lender before starting to show properties in Orlando, FL.

5. James had to pay $20,845 in commission to the listing broker, assuming a commission rate of 5.5%.

1. Given the financial difficulties faced by Lisa, working with her lender to sell the property as a short sale is a viable option. A short sale allows the property to be sold for less than the outstanding mortgage balance, with the lender's approval, to avoid foreclosure. This can provide some relief for Lisa and prevent further financial complications.

2. In this scenario, the owner sent an email rescinding the counteroffer before the buyers responded. As a result, there is no contract in place since the counteroffer was effectively withdrawn. The buyers are not obligated to accept the counteroffer, and negotiations would need to restart if they still wish to proceed with the purchase.

3. After obtaining a Florida real estate sales associate license, Wendy is required to complete 45 hours of post-license education before her first license renewal date. This education is designed to provide new licensees with additional knowledge and skills necessary for their real estate career.

4. Before Rachel starts showing properties to her client, it is essential to encourage the client to obtain a pre-approval letter from a lender. This letter confirms that the client has been pre-approved for a specific loan amount, providing a clear understanding of their budget and enabling them to make informed decisions during the house-hunting process.

5. Assuming a commission rate of 5.5% on the sale of James' home, he would have to pay $20,845 in commission to the listing broker. The commission is typically split between the listing broker and the selling broker, but the specific breakdown is not provided in the question.

a) The annual demand is 420.

b) The weekly demand forecast is 8.08

c) The EOQ would be approximately 41

d) The reorder point is 45.12

e) The total annual cost is 102439.02

f) The pipeline inventory is 32.32

g) The new reorder point is 48.82

a) To calculate the annual demand, you need to use your student number. For example, if your student number is BBAW190102, the last digit is 2. So, the annual demand would be 400 + 10 x 2 = 420.

b) To calculate the weekly demand forecast for 2021, you need to divide the annual demand by the number of weeks in a year. Assuming there are 52 weeks in a year, the weekly demand forecast would be 420 / 52 = 8.08 (rounded to two decimal places).

c) The economic order quantity (EOQ) can be calculated using the formula EOQ = sqrt((2DS) / H), where D is the annual demand, S is the ordering cost per order, and H is the annual holding cost. In this case, D is the annual demand calculated in part a, S is $1000, and H is $500. Plugging in these values, the EOQ would be sqrt((2 x 420 x 1000) / 500) = sqrt(840000 / 500) = sqrt(1680) ≈ 41 (rounded to the nearest whole number).

d) The reorder point is the level of inventory at which a new order should be placed. It can be calculated using the formula reorder point = demand during lead time + safety stock. The demand during lead time is the average demand per week multiplied by the lead time, which is 8.08 x 4 = 32.32 (rounded to two decimal places). The safety stock is the z-score multiplied by the standard deviation of weekly demand. The z-score for a 90% cycle service level is 1.28 (given in the question) and the standard deviation of weekly demand is 10 (given in the question). So, the safety stock would be 1.28 x 10 = 12.8 (rounded to one decimal place). Therefore, the reorder point would be 32.32 + 12.8 = 45.12 (rounded to two decimal places).

e) The total annual cost of managing the inventory can be calculated using the formula TC = (S x D/Q) + (H x (Q/2 + s)), where S is the ordering cost per order, D is the annual demand, Q is the economic order quantity, H is the annual holding cost, and s is the safety stock. Plugging in the values, the total annual cost would be (1000 x 420/41) + (500 x (41/2 + 12.8)) = 102439.02 (rounded to two decimal places).

f) The pipeline inventory refers to the inventory that is in transit or being processed. In this case, since the lead time is 4 weeks, the pipeline inventory would be the average demand per week multiplied by the lead time. So, the pipeline inventory would be 8.08 x 4 = 32.32 (rounded to two decimal places).

g) To achieve a 95% cycle service level, we need to calculate the new safety stock and reorder point. The z-score for a 95% cycle service level is 1.65 (given in the question). Using the same formula as in part d, the new safety stock would be 1.65 x 10 = 16.5 (rounded to one decimal place). Therefore, the new reorder point would be 32.32 + 16.5 = 48.82 (rounded to two decimal places).

The amount still owed on the car after the 24th payment is $15,213.28.

First, let's find the monthly interest rate. We can calculate this by dividing the nominal annual interest rate by the number of compounding periods in a year. Here, we have monthly compounding, so:

Monthly interest rate = Nominal annual interest rate ÷ 12

= 7% ÷ 12

= 0.00583 (rounded to 5 decimal places)

Next, let's calculate the loan amount using the present value formula:

PV = PMT × [1 - (1 + r)^(-n) ÷ r]

where PV = present value (loan amount), PMT = monthly payment, r = monthly interest rate, and n = total number of payments.

PV = $400 × [1 - (1 + 0.00583)^(-72) ÷ 0.00583]

= $23,122.52 (rounded to 2 decimal places)

To find out how much is still owed on the car after the 24th payment, we can use the remaining balance formula:

R = PV × (1 + r)^n - PMT × [(1 + r)^n - 1 ÷ r]

where R = remaining balance, PV = present value (loan amount), r = monthly interest rate, n = number of payments made, and PMT = monthly payment.

R = $23,122.52 × (1 + 0.00583)^24 - $400 × [(1 + 0.00583)^24 - 1 ÷ 0.00583]

R = $15,213.28 (rounded to 2 decimal places)

Step-by-step explanation:

Part One: The vector representing the path to the object is <30, 20>.

Part Two: The object is approximately 36.06 meters away from the human character.

Part Three: The angle of rotation needed for the first human character to face the second human character is approximately 45 degrees.

Part One: To represent the path to the object using a vector, we can consider the displacement from the human character to the object.

Since the object is 30 meters to the right and 20 meters in front of the human character, the vector representing this displacement is <30, 20>.

The first component of the vector represents the displacement in the x-direction (horizontal), and the second component represents the displacement in the y-direction (vertical).

Part Two: To find the distance between the object and the human character, we can use the Pythagorean theorem.

The distance is given by the magnitude of the vector representing the displacement.

Using the formula for magnitude (or length) of a vector, the distance is approximately √(30^2 + 20^2) = √(900 + 400) = √1300 ≈ 36.06 meters.

Part Three: To determine the angle of rotation needed for the first human character to face the second human character, we can create a vector between the two humans by subtracting the position vector of the first human from the position vector of the second human.

Let's assume the position vector of the second human is <-40, 50>. Then, the vector between the two humans is given by <(-40 - 30), (50 - 20)> = <-70, 30>.

Next, we can calculate the angle between the vectors <30, 20> and <-70, 30> using the dot product formula and trigonometry.

The dot product of two vectors A and B is defined as A · B = |A| |B| cos(theta), where |A| and |B| are the magnitudes of the vectors and theta is the angle between them.

Solving for theta, we have cos(theta) = (A · B) / (|A| |B|). Plugging in the values, cos(theta) = ((30)(-70) + (20)(30)) / (√(30^2 + 20^2) √((-70)^2 + 30^2)). Calculating this expression gives us cos(theta) ≈ -0.916.

Finally, taking the inverse cosine (arccos) of -0.916, we find the angle of rotation needed is approximately 22.91 degrees.

The chart shows that at 0 minutes, she ran 0 miles. At 16 minutes, she ran 8 miles. At 24 minutes, she ran 1 mile. At 8 minutes, she ran 2 miles. And at 3 minutes, she ran 3 miles.

To find out how many miles she can run in 72 minutes, we need to determine her running pace, which is the number of miles she can run per minutes.

We can calculate the average pace using the given data points.

From the data, we can observe that her pace varies.

However, we can approximate her pace by calculating the average speed over the recorded distances.

Total miles covered: 0 + 8 + 1 + 2 + 3 = 14 miles

Total time taken: 0 + 16 + 24 + 8 + 3 = 51 minutes

Average pace = Total miles covered / Total time taken

Average pace = 14 miles / 51 minutes

To find the number of miles she can run in 72 minutes, we can use the average pace:

Miles in 72 minutes = Average pace [tex]\times[/tex] 72 minutes

Miles in 72 minutes = (14 miles / 51 minutes) [tex]\times[/tex] 72 minutes

a)The industry output will be: Q = qA + qB.

b) The industry output will be: Q = qA + qB.

a) Bertrand Model:

In the Bertrand Model, both firms produce the same quality products at a constant marginal cost of X. Both companies attempt to maximize their own profits by selecting the lowest price. Firm A produces qA, while firm B produces qB. The firms would earn no profits if they set the same price.

Assume that each firm offers the same price P. The industry supply will be Q = qA + qB. The market demand is given by Q = Y - P. Substituting the value of Q, we get: Y - P = qA + qB.

The industry price is given by: P = (Y - Q)/2 = (Y - qA - qB)/2. Putting the value of Y and Q, we have: P = [(B + C) - (A + D/2) - qA - qB]/2 = (B + C - A - D/2)/2 - qA/2 - qB/2.

The industry output will be: Q = qA + qB.

Consumer surplus is given by the difference between what consumers are willing to pay and the market price of a good, summed over all customers. The consumer surplus is calculated by taking the area between the demand curve and the market price up to the equilibrium output.

Consumer Surplus = 1/2 (B + C - A - D/2 - P) * Q = 1/2 (B + C - A - D/2 - [(qA + qB)/2]) * [(qA + qB)].

Industry profit is given by: π = qA * P + qB * P - X(qA + qB) = qA * qB / 2Q - X(Q/2).

Deadweight Loss (DWL) is the loss of economic efficiency that occurs when the equilibrium output is not achieved. DWL is given by: DWL = [1/2 (qa + qb) - Q]/2.

b) Cournot Model:

In the Cournot Model, both firms produce identical products with a constant marginal cost of X. Both firms attempt to maximize their profits by selecting their output levels qA and qB. Let Q = qA + qB be the industry's output.

Substituting the value of Q, we get: Y - P = qA + qB.

The industry price is given by: P = (Y - qA - qB)/2 = (B + C - A - D/2)/2 - qA/2 - qB/2.

The industry output will be: Q = qA + qB.

Consumer surplus is given by the difference between what consumers are willing to pay and the market price of a good, summed over all customers. The consumer surplus is calculated by taking the area between the demand curve and the market price up to the equilibrium output.

Consumer Surplus = 1/2 (B + C - A - D/2 - P) * Q.

Industry profit is given by: π = (qA + qB) * (P - X) - (qA^2 + qB^2)/2.

Deadweight Loss (DWL) is the loss of economic efficiency that occurs when the equilibrium output is not achieved. DWL is given by: DWL = [(qa - qb)^2 - (qA + qB)^2]/2.

To investigate whether the span of a person's dominant hand is greater than that of their non-dominant hand, the most appropriate statistical technique would be the Paired samples t-test.

The Paired samples t-test is used when comparing the means of two related groups or conditions. In this case, the dominant and non-dominant hands are related because they belong to the same individuals in the study. By comparing the means of the dominant and non-dominant hand spans, we can determine if there is a significant difference between the two.

The other options listed, ANOVA (Analysis of Variance), Independent samples t-test, Wilcoxon's matched-pairs signed rank test, and Mann-Whitney U test, are not suitable for this scenario because they are designed for different types of comparisons:

- ANOVA is used when comparing the means of three or more independent groups, which is not the case here.

- Independent samples t-test is used when comparing the means of two independent groups, which is not the case here as the measurements are paired.

- Wilcoxon's matched-pairs signed rank test and Mann-Whitney U test are non-parametric tests that are used when the data do not meet the assumptions of parametric tests. However, in this case, we have paired measurements, and the paired samples t-test is the appropriate parametric test.

To determine which statements are true, let's analyze each option:

A. The dimension of the null space of A is equal to 0.

The null space of a matrix consists of all vectors that, when multiplied by the matrix, result in the zero vector. Since the rank of A is 5, it means that the number of linearly independent columns is 5. Therefore, the dimension of the null space, which represents the number of linearly dependent columns, is equal to the total number of columns (6) minus the rank (5), resulting in a dimension of 1. Therefore, statement A is false.

B. The rows of A are linearly independent.

Since the rank of A is 5, it means that there are 5 linearly independent rows. Therefore, statement B is true.

C. The columns of A are linearly independent.

Since the rank of A is 5, it means that there are 5 linearly independent columns. Therefore, statement C is true.

D. The rank of A^T is equal to 6.

The rank of the transpose of a matrix, A^T, is equal to the rank of the original matrix, A. Since the rank of A is given to be 5, the rank of A^T is also 5. Therefore, statement D is false.

E. The dimension of the row space of A is 1.

Answer:

The flow rate in mL/hr for infusing 2 liters of 5% dextrose over 16 hours is 125 mL/hr.

Step-by-step explanation:

We can use the following formula to calculate the flow rate:

Flow rate (mL/hr) = Volume to be infused (mL) / Time of infusion (hr)

First, we need to convert the total volume of 2 liters to mL:

2 liters = 2000 mL

Next, we can plug in the values:

Flow rate = 2000 mL / 16 hours

Flow rate = 125 mL/hr

Therefore, the flow rate in mL/hr for infusing 2 liters of 5% dextrose over 16 hours is 125 mL/hr.

For determining whether two lines are parallel or perpendicular, we need to compare their slopes.

For Line 1: 8x - 6y = -2,

Rearrange the equation to the slope-intercept form (y = mx + b) where m is the slope of the line.

By isolating y:

-6y = -8x - 2

Dividing by -6, we get:

y = (4/3)x + 1/3

The slope of Line 1 is 4/3.

For Line 2: y = (3/4)x - 5, the equation is already in slope-intercept form

so the slope of Line 2 is 3/4.

For Line 3: 4y = 3x + 5, again rearranging the equation in (y=mx+c) and then solving for y

On dividing by 4

y = (3/4)x + 5/4

The slope of Line 3 is 3/4.

To determine that lines are parallel, we need to check that their slopes are equal, and to check if they are perpendicular, we need to see if the product of their slopes is -1. So,

On comparing the slopes of Line 1 (4/3) and Line 2 (3/4), they are not equal. Therefore, Line 1 and Line 2 are not parallel.

On calculating (4/3) * (3/4), we get 1. Since the product is not -1, Line 1 and Line 2 are not perpendicular.

Moving on to Line 1 and Line 3 their slopes (4/3), and (3/4) respectively are not equal, therefore, Line 1 and Line 3 are not parallel.

Since the product of their slope is not -1, so Line 1 and Line 3 are not perpendicular.

Now on comparing the slopes of Line 2 (3/4) and Line 3 (3/4), we see that they are equal. Hence, Line 2 and Line 3 are parallel but their product is not equal to -1 so they are not perpendicular.

In summary:

Line 1 and Line 2 are not parallel or perpendicular.

Line 1 and Line 3 are not parallel or perpendicular.

Line 2 and Line 3 are parallel.

a) The function y₁(t) is (2/3)[tex]e^{2t/7}[/tex] + (1/3)[tex]e^{-4t/7}[/tex].

b) The function y₂(t) is (4/3)[tex]e^{2t/7}[/tex] - (4/3)[tex]e^{-4t/7}[/tex].

c) The Wronskian W(t) is (-2/3)[tex]e^{2t/7}[/tex] + (1/3)[tex]e^{-4t/7}[/tex].

a) To find the function y₁(t) which is the solution of 49y′′ + 14y′ − 8y = 0 with initial conditions y₁(0) = 1 and y₁′(0) = 0, we can assume a solution of the form y₁(t) = [tex]e^{rt}[/tex], where r is a constant.

Taking the derivatives, we have:

y₁′(t) = r[tex]e^{rt}[/tex]

y₁′′(t) = r²[tex]e^{rt}[/tex]

Substituting these into the differential equation, we get:

49(r²[tex]e^{rt}[/tex]) + 14(r[tex]e^{rt}[/tex]) - 8([tex]e^{rt}[/tex]) = 0

Simplifying the equation:

[tex]e^{rt}[/tex] * (49r² + 14r - 8) = 0

For this equation to hold true for all t, the expression inside the parentheses must equal zero:

49r² + 14r - 8 = 0

To solve this quadratic equation, we can use the quadratic formula:

r = (-b ± √(b² - 4ac)) / 2a

In this case, a = 49, b = 14, and c = -8. Plugging in the values, we get:

r = (-14 ± √(14² - 4 * 49 * -8)) / (2 * 49)

r = (-14 ± √(196 + 1568)) / 98

r = (-14 ± √(1764)) / 98

r = (-14 ± 42) / 98

Simplifying further:

r₁ = (28 / 98) = 2/7

r₂ = (-56 / 98) = -4/7

Thus, the solutions for r are r₁ = 2/7 and r₂ = -4/7.

Now, we can write the general solution:

y₁(t) = C₁[tex]e^{2t/7}[/tex] + C₂[tex]e^{-4t/7[/tex]

Applying the initial conditions, we have:

y₁(0) = C₁[tex]e^0[/tex] + C₂[tex]e^0[/tex] = C₁ + C₂ = 1

y₁′(0) = (2/7)C₁[tex]e^0[/tex] + (-4/7)C₂[tex]e^0[/tex] = (2/7)C₁ - (4/7)C₂ = 0

From these equations, we can solve for C₁ and C₂:

C₁ + C₂ = 1 --> C₁ = 1 - C₂

(2/7)C₁ - (4/7)C₂ = 0

Substituting the value of C₁ from the first equation into the second equation, we get:

(2/7)(1 - C₂) - (4/7)C₂ = 0

(2/7) - (2/7)C₂ - (4/7)C₂ = 0

(6/7)C₂ = - (2/7)

C₂ = 1/3

Substituting the value of C₂ back into the first equation, we find:

C₁ = 1 - C₂ = 1 - 1/3 = 2/3

Therefore, the function y₁(t) which satisfies the given differential equation and initial conditions is:

y₁(t) = (2/3)[tex]e^{2t/7[/tex] + (1/3)[tex]e^{-4t/7[/tex]

b) To find the function y₂(t) which is the solution of 49y′′ + 14y′ − 8y = 0 with initial conditions y₂(0) = 0 and y₂′(0) = 1, we follow a similar process as in part (a).

Assuming a solution of the form y₂(t) = e^(rt), we get:

49(r²[tex]e^{rt[/tex]) + 14(r[tex]e^{rt[/tex]) - 8([tex]e^{rt[/tex]) = 0

This leads to the equation:

49r² + 14r - 8 = 0

Solving this quadratic equation, we find:

r₁ = 2/7

r₂ = -4/7

The general solution becomes:

y₂(t) = C₃[tex]e^{2t/7[/tex] + C₄[tex]e^{-4t/7[/tex]

Applying the initial conditions:

y₂(0) = C₃[tex]e^0[/tex] + C₄[tex]e^0[/tex] = C₃ + C₄ = 0

y₂′(0) = (2/7)C₃[tex]e^0[/tex] - (4/7)C₄[tex]e^0[/tex] = (2/7)C₃ - (4/7)C₄ = 1

Solving these equations, we find:

C₃ = 4/3

C₄ = -4/3

Therefore, the function y₂(t) which satisfies the given differential equation and initial conditions is:

y₂(t) = (4/3)[tex]e^{2t/7[/tex] - (4/3)[tex]e^{-4t/7[/tex]

c) The Wronskian, denoted by W(t), is given by the determinant of the matrix formed by the coefficients of y₁(t) and y₂(t) and their derivatives:

W(t) = | y₁(t) y₂(t) |

| y₁′(t) y₂′(t) |

We already found y₁(t) and y₂(t) in parts (a) and (b), so we can now find their derivatives and calculate the Wronskian.

Taking the derivatives:

y₁′(t) = (2/7)[tex]e^{2t/7[/tex] - (4/7)[tex]e^{-4t/7[/tex]

y₂′(t) = (4/7)[tex]e^{2t/7[/tex] + (4/7)[tex]e^{-4t/7[/tex]

Substituting these derivatives into the Wronskian formula:

W(t) = | (2/3)[tex]e^{2t/7[/tex] + (1/3)[tex]e^{-4t/7[/tex] (4/3)[tex]e^{2t/7[/tex] - (4/3)[tex]e^{-4t/7[/tex] |

Simplifying the determinant, we get:

W(t) = (2/3)[tex]e^{2t/7[/tex] + (1/3)[tex]e^{-4t/7[/tex] - (4/3)[tex]e^{2t/7[/tex] + (4/3)[tex]e^{-4t/7[/tex]

= (-2/3)[tex]e^{2t/7[/tex] + (1/3)[tex]e^{-4t/7[/tex]

The solution to the differential equation is:y(x) = 26e^x - e^4x + e^7x

We can solve the given differential equation, y‴ − 12y′′ + 35y′ = 24ex by assuming that y = er

Given, y‴ − 12y′′ + 35y′ = 24exy = erx

Let's substitute y into the differential equation:y‴ − 12y′′ + 35y′ = 24ex → r³erx − 12r²erx + 35rerx = 24ex

Now factor erx from the left side to get:r³ - 12r² + 35r = 24erx

Divide both sides by erx:

r³/erx - 12r²/erx + 35r/erx = 24ex/erx→ r³er^-x - 12r²er^-x + 35rer^-x = 24→ r³e^-x - 12r²e^-x + 35re^-x = 24

Now we can solve for r by factoring the left side:r³e^-x - 12r²e^-x + 35re^-x - 24 = 0

This can be factored into:(r - 1)(r - 4)(r - 7)e^-x = 0

So we have:r = 1, 4, 7

We can write the general solution as:

y(x) = C1e^x + C2e^4x + C3e^7x

where C1, C2, and C3 are constants.

Let's use the initial conditions to find these constants:

y(0) = C1 + C2 + C3 = 24y′(0) = C1 + 4C2 + 7C3 = 18y′′(0) = C1 + 16C2 + 49C3 = 10

Now we can solve for C1, C2, and C3.

Using the first equation, we get:C1 + C2 + C3 = 24

C1 = 24 - C2 - C3

Using the second equation, we get:

C1 + 4C2 + 7C3 = 18(24 - C2 - C3) + 4

C2 + 7C3 = 18-3

C2 - 6C3 = -6

C2 + 2C3 = 2

C2 = -2/4 = -1

Now we can find C3 from the first equation:

C1 + C2 + C3 = 24(24 - C2 - C3) - C2 - C3 + C3 = 24

C3 = 1

Substituting C2 and C3 back into C1 = 24 - C2 - C3, we get:

C1 = 24 - (-1) - 1 = 26

Answer:

The equations of bisectors of the angles are:

[tex]3x+11y-10=0[/tex]

[tex]33x-9y=0[/tex]

The bisector of the acute angle is 33x - 9y = 0.

Step-by-step explanation:

Let line 3x - 2y + 1 = 0 be defined by the equation a₁x + b₁y + c₁ = 0.

Let line 18x + y - 5 = 0 be defined by the equation a₂x + b₂y + c₂ = 0.

The formulas for the two angle bisectors of lines a₁x + b₁y + c₁ = 0 and a₂x + b₂y + c₂ = 0 are:

[tex]\boxed{\dfrac{a_1x+b_1y+c_1}{\sqrt{{a_1}^2+{b_1}^2}}=\pm\dfrac{a_2x+b_2y+c_2}{\sqrt{{a_2}^2+{b_2}^2}}}[/tex]

The two angle bisectors are perpendicular.

Substitute the values of a₁, b₁, c₁, a₂, b₂, and c₂ into both formulas.

Equation of bisector 1

[tex]\begin{aligned}\dfrac{3x-2y+1}{\sqrt{{3}^2+(-2)^2}}&=\dfrac{18x+y+(-5)}{\sqrt{18^2+1^2}}\\\\\dfrac{3x-2y+1}{\sqrt{13}}&=\dfrac{18x+y-5}{5\sqrt{13}}\\\\3x-2y+1&=\dfrac{18x+y-5}{5}\\\\5(3x-2y+1)&=18x+y-5\\\\15x-10y+5&=18x+y-5\\\\3x+11y-10&=0\end{aligned}[/tex]

Equation of bisector 2

[tex]\begin{aligned}\dfrac{3x-2y+1}{\sqrt{{3}^2+(-2)^2}}&=-\dfrac{18x+y+(-5)}{\sqrt{18^2+1^2}}\\\\\dfrac{3x-2y+1}{\sqrt{13}}&=-\dfrac{18x+y-5}{5\sqrt{13}}\\\\3x-2y+1&=-\dfrac{18x+y-5}{5}\\\\-5(3x-2y+1)&=18x+y-5\\\\-15x+10y-5&=18x+y-5\\\\33x-9y&=0\end{aligned}[/tex]

Therefore, the equations of bisectors of the angles between the given lines are:

[tex]3x+11y-10=0[/tex]

[tex]33x-9y=0[/tex]

[tex]\hrulefill[/tex]

To identify the bisector of the acute angle, we need to calculate the angle between any one of the bisectors and one of the lines.

The formula for the angle between two lines a₁x + b₁y + c₁ = 0 and a₂x + b₂y + c₂ = 0 is:

[tex]\tan \theta=\left|\dfrac{a_2b_1-a_1b_2}{a_1a_2+b_1b_2} \right|[/tex]

Let's find the angle θ between the bisector 6x + 6y - 1 = 0, and the line 3x - 2y + 1 = 0.

Therefore:

Substitute these values into the formula for the angle between two lines:

[tex]\tan \theta=\left|\dfrac{(3)(-9)-(33)(-2)}{(33)(3)+(-9)(-2)} \right|[/tex]

[tex]\tan \theta=\left|\dfrac{39}{117} \right|[/tex]

[tex]\tan \theta=\left|\dfrac{1}{3} \right|[/tex]

As tan θ < 1, the angle θ between the bisector and the line must be less than 45°. This means that the angle between the two given lines is less than 90°.

Since an acute angle measures less than 90°, this means that 33x - 9y = 0 is the bisector of the acute angle between the given lines.

Note: On the attached diagram, the given lines are shown in black, the bisector of the acute angle is the red dashed line, and the bisector of the obtuse angle is the green dashed line.

Vertically compressing the exponential parent function f(x) = 2^x by a factor of 3 means multiplying every function value by 1/3, resulting in a steeper and narrower curve closer to the x-axis.

If we vertically compress the exponential parent function f(x) = 2^x by a factor of 3, it means that every point on the graph of the function will be compressed closer to the x-axis. In other words, the function values will be multiplied by 1/3.

Let's consider a point on the original exponential function, (x, f(x)). After the vertical compression, this point will have the coordinates (x, (1/3)f(x)). For example, if f(x) = 8 for some x, after compression, the corresponding point will be (x, (1/3)(8)) = (x, 8/3).

This vertical compression affects all points on the graph uniformly, resulting in a steeper and narrower curve compared to the original exponential function.

The y-values of the compressed function will be one-third of the y-values of the original function for each x-value. Therefore, the graph will be squeezed vertically, with the y-values closer to the x-axis.

(a) The explicit formula R(n) = 2n - 1.

(b) L(n) = n(n - 1).

(c) Number of odd numbers = 1 - n² + 3n.

(d) an = n³ + 2n² + n + 2.

(a) The explicit formula R(n) for the rightmost odd number on the left-hand side of the nth row, let's examine the pattern. In each row, the number of odd numbers on the left side is equal to the row number (n).

The first row (n = 1) has 1 odd number: a1.

The second row (n = 2) has 2 odd numbers: a2 and 3.

The third row (n = 3) has 3 odd numbers: 5, 7, and 9.

We can observe that in the nth row, the first odd number is given by n, and the subsequent odd numbers are consecutive odd integers. Therefore, we can express R(n) as:

R(n) = n + (n - 1) = 2n - 1.

To justify this formula, we can use mathematical induction. First, we verify that R(1) = 1, which matches the first row. Then, assuming the formula holds for some arbitrary kth row, we can show that it holds for the (k+1)th row:

R(k+1) = k + 1 + k = 2k + 1.

Since 2k + 1 is the (k+1)th odd number, the formula holds for the (k+1)th row.

(b) The formula L(n) for the leftmost odd number in the nth row, we can observe that the leftmost odd number in each row is given by the sum of odd numbers from 1 to (n-1). We can express L(n) as:

L(n) = 1 + 3 + 5 + ... + (2n - 3).

To justify this formula, we can use the formula for the sum of an arithmetic series:

S = (n/2)(first term + last term).

In this case, the first term is 1, and the last term is (2n - 3). Plugging these values into the formula, we have:

S = (n/2)(1 + 2n - 3) = (n/2)(2n - 2) = n(n - 1).

Therefore, L(n) = n(n - 1).

(c) The number of odd numbers on the left-hand side in the nth row can be calculated by subtracting the leftmost odd number from the rightmost odd number and adding 1. Therefore, the number of odd numbers in the nth row is:

Number of odd numbers = R(n) - L(n) + 1 = (2n - 1) - (n(n - 1)) + 1 = 2n - n² + n + 1 = 1 - n² + 3n.

(d) Based on the previous steps and the fact that each row has an even distribution of odd numbers, we can argue that the value of an, which represents the sum of odd numbers in the nth row, should be equal to the sum of the odd numbers in that row. Using the formula for the sum of an arithmetic series, we can find the sum of the odd numbers in the nth row:

Sum of odd numbers = (Number of odd numbers / 2) * (First odd number + Last odd number).

Sum of odd numbers = ((1 - n² + 3n) / 2) * (L(n) + R(n)).

Substituting the formulas for L(n) and R(n) from earlier, we get:

Sum of odd numbers = ((1 - n² + 3n) / 2) * (n(n - 1) + 2

n - 1).

Simplifying further:

Sum of odd numbers = (1 - n² + 3n) * (n² - n + 1).

Sum of odd numbers = n³ - n² + n - n² + n - 1 + 3n² - 3n + 3.

Sum of odd numbers = n³ + 2n² + n + 2.

Hence, the value of an is given by the sum of the odd numbers in the nth row, which is n³ + 2n² + n + 2.

To solve the initial value problem dx/dy = -10-x, y(0) = -1, we can use separation of variables. We start by separating the variables, placing the dx term on one side and the dy term on the other side. This gives us dx = -10-x dy.

Next, we integrate both sides of the equation. On the left side, we integrate dx, which gives us x. On the right side, we integrate -10-x dy, which can be rewritten as -10[tex]e^{-x}[/tex] dy. Integrating -10[tex]e^{-x}[/tex] dy gives us -10[tex]e^{-x}[/tex] + C, where C is the constant of integration.

Now, we solve for y by isolating it. We rewrite -10e-x + C as -10 - e-x + C to match the initial condition y(0) = -1. Plugging in the value of y(0), we have -10 - [tex]e^{0}[/tex] + C = -1. Simplifying this equation, we find C = 9.

Finally, we substitute the value of C back into our equation -10 - [tex]e^{-x}[/tex] + C, giving us -10 - [tex]e^{-x}[/tex] + 9. Simplifying further, we get y = -1 - [tex]e^{-x}[/tex].

[tex]\left\{\begin{pmatrix}1\\2\\2\end{pmatrix},\begin{pmatrix}-\frac{3}{2}\\\frac{1}{2}\\1\end{pmatrix}\right\} \Rightarrow Orthonormalize \Rightarrow \left\{\frac{1}{3}\begin{pmatrix}1\\2\\2\end{pmatrix},\frac{1}{\sqrt{14}}\begin{pmatrix}-3\\1\\2\end{pmatrix}\right\}[/tex]

So, the orthonormal basis for the subspace W is

[tex]\left\{\frac{1}{3}\begin{pmatrix}1\\2\\2\end{pmatrix},\frac{1}{\sqrt{14}}\begin{pmatrix}-3\\1\\2\end{pmatrix}\right\}[/tex]

Now, let's compute the projection of X onto the subspace W using the above formula.

[tex]proj_WX =\frac{X\cdot w}{\left\|w\right\|^2}w[/tex]

[tex]proj_WX =\frac{\begin{pmatrix}2\\9\\4\end{pmatrix}\cdot \frac{1}{3}\begin{pmatrix}1\\2\\2\end{pmatrix}}{\left\|\frac{1}{3}\begin{pmatrix}1\\2\\2\end{pmatrix}\right\|^2}\frac{1}{3}\begin{pmatrix}1\\2\\2\end{pmatrix} + \frac{\begin{pmatrix}2\\9\\4\end{pmatrix}\cdot \frac{1}{\sqrt{14}}\begin{pmatrix}-3\\1\\2\end{pmatrix}}{\left\|\frac{1}{\sqrt{14}}\begin{pmatrix}-3\\1\\2\end{pmatrix}\right\|^2}\frac{1}{\sqrt{14}}\begin{pmatrix}-3\\1\\2\end{pmatrix}[/tex]

[tex]proj_WX = \frac{14}{27}\begin{pmatrix}1\\2\\2\end{pmatrix} + \frac{2}{7}\begin{pmatrix}-3\\1\\2\end{pmatrix}[/tex]

[tex]\Rightarrow proj_WX = \begin{pmatrix}\frac{4}{3}\\\frac{14}{3}\\\frac{10}{3}\end{pmatrix}[/tex]

Therefore, the orthogonal projection of the vector X = (2 9 4) onto the subspace W = span [(1 (2 2 1 2), -2) is

[tex]proj_WX = \begin{pmatrix}\frac{4}{3}\\\frac{14}{3}\\\frac{10}{3}\end{pmatrix}[/tex]

The solution is given by

y = yc + yp

  = c1 e^(-4x) + c2 xe^(-4x) - x^3/64 e^(-4x)

where c1 and c2 are constants.

Given differential equation is y" + 8y' + 16y = e^(-4x) x^3

To find particular solution, we consider the trial solution of the form, yp = (ax^3 + bx^2 + cx + d)e^(-4x)

Differentiate the above equation,

yp' = [(3ax^2 + 2bx + c)e^(-4x) + (-4ax^3 - 4bx^2 - 4cx - 4d)e^(-4x)]

yp" = [(6ax + 2b - 8ax^2 - 8bx - 8c)e^(-4x) + (16ax^3 + 16bx^2 + 16cx + 16d)e^(-4x)]

Substitute these values in the differential equation,

y" + 8y' + 16y = e^(-4x) x^3[(6ax + 2b - 8ax^2 - 8bx - 8c)e^(-4x) + (16ax^3 + 16bx^2 + 16cx + 16d)e^(-4x)] + 8[(3ax^2 + 2bx + c)e^(-4x) + (-4ax^3 - 4bx^2 - 4cx - 4d)e^(-4x)] + 16[(ax^3 + bx^2 + cx + d)e^(-4x)] = e^(-4x) x^3

Simplify the equation,

[-48ax^3 + 8bx^2 + 8cx + (16a - 16b + 16c + 16d)]e^(-4x) + (16ax^3 + 16bx^2 + 16cx + 16d)e^(-4x) + 8(3ax^2 + 2bx + c)e^(-4x) = x^3 e^(-4x)

Integrating the above equation,

we geta = 0b = 0c = 0d = -1/64

Therefore, the particular solution is

yp = -x^3/64 e^(-4x)
