The function a)/(x) = x + 1 is not continuous at x = 1, violating the condition of continuity at that point. The function b)/(x) is not specified, so it is not possible to identify a point where it is not continuous.

To determine points where a function is not continuous, we need to examine the three conditions of continuity:

The function is defined at the point: For the function a)/(x) = x + 1, it is defined for all real values of x, so this condition is satisfied.

The limit exists at the point: We calculate the limit of a)/(x) as x approaches 1. Taking the limit as x approaches 1 from the left side, we get lim(x→1-) (x + 1) = 2. Taking the limit as x approaches 1 from the right side, we get lim(x→1+) (x + 1) = 2. Both limits are equal, so this condition is satisfied.

The value of the function at the point is equal to the limit: Evaluating a)/(x) at x = 1, we get a)/(1) = 2. Comparing this with the limit we calculated earlier, we see that the function has the same value as the limit at x = 1, satisfying this condition of continuity.

Therefore, the function a)/(x) = x + 1 is continuous for all values of x, including x = 1. As for the function b)/(x), without specifying the actual function, it is not possible to identify a point where it is not continuous.

To solve the given linear system of differential equations, we can use the method of solving a system of linear first-order differential equations.

We start by rewriting the equations in matrix form:

Let X = [x, y] be the vector of unknown functions, and A = [tex]\left[\begin{array}{ccc}19&-20\\-15&-16\\\end{array}\right][/tex] be the coefficient matrix.

Then the given system can be written as X' = AX.

To find the solution, we need to find the eigenvalues and eigenvectors of the coefficient matrix A.

By calculating the eigenvalues, we find [tex]\lambda_1[/tex] = -3 and [tex]\lambda_2[/tex] = 2.

For each eigenvalue, we can find the corresponding eigenvector.

For  [tex]\lambda_1[/tex]= -3, the corresponding eigenvector is [1, -3].

For [tex]λ_2[/tex] = 2, the corresponding eigenvector is [4, -1].

Using these eigenvectors, we can construct the general solution as X(t) = [tex]c_1e^{(\lambda_1t)}[1, -3] + c_2e^{(\lambda_2t)}[4, -1][/tex].

Applying the initial conditions x(0) = 9 and y(0) = -6, we can determine the values of [tex]c_1[/tex] and [tex]c_2[/tex].

Substituting these values into the general solution, we obtain the specific solution x(t) = [tex]3e^t - 6e^{(-4t)}[/tex] and y(t) = [tex]-6e^{(-4t)} - 3e^t[/tex].

To determine the value of y such that the points (-6, -5), (12, y), and (3, 5) are collinear, we can use the slope formula.

The slope between two points (x1, y1) and (x2, y2) is given by (y2 - y1) / (x2 - x1).

Using the first two points (-6, -5) and (12, y), we can calculate the slope:

slope = (y - (-5)) / (12 - (-6)) = (y + 5) / 18

Now, we compare this slope to the slope between the second and third points (12, y) and (3, 5):

slope = (5 - y) / (3 - 12) = (5 - y) / (-9) = (y - 5) / 9

For the points to be collinear, the slopes between any two pairs of points should be equal.

Setting the two slopes equal to each other, we have:

(y + 5) / 18 = (y - 5) / 9

Simplifying and solving for y:

2(y + 5) = y - 5

2y + 10 = y - 5

y = -15

Therefore, the value of y that makes the points (-6, -5), (12, y), and (3, 5) collinear is -15.

The marginal revenue is equal to the price of an engagement ring plus the product of the number of rings sold and the rate at which the price decreases per additional ring sold, which is -$0.80.

To find the marginal revenue, we need to determine the rate of change of revenue with respect to the number of rings sold.

Let's denote the price of an engagement ring as P and the number of rings sold as N. The weekly revenue (R) can be expressed as:

[tex]R = P * N[/tex]

We are given that the price is increasing at a rate of $25 per $1 increase, so we can write the rate of change of price (dP/dN) as:

[tex]dP/dN = $25[/tex]

We are also given that the price is decreasing at a rate of $0.80 for every additional ring sold, which implies that the rate of change of price with respect to the number of rings (dP/dN) is:

[tex]dP/dN = -$0.80[/tex]

To find the marginal revenue (MR), we can use the product rule of differentiation, which states that the derivative of the product of two functions is the first function times the derivative of the second function plus the second function times the derivative of the first function.

Applying the product rule to the revenue function R = P * N, we have:

[tex]dR/dN = P * (dN/dN) + N * (dP/dN)[/tex]

Since dN/dN is 1, we can simplify the equation to:

[tex]dR/dN = P + N * (dP/dN)[/tex]

Substituting the given values, we have:

[tex]dR/dN = P + N * (-$0.80)[/tex]

The marginal revenue (MR) is the derivative of the revenue function with respect to the number of rings sold. So, the marginal revenue is:

To evaluate the improper integral ∫(x²)dx or determine if it diverges, we first integrate the function.

∫(x²)dx = (1/3)x³+ C,

where C is the constant of integration.

Now, let's analyze the behavior of the integral at the boundaries to determine if it converges or diverges.

Case 1: Integrating from negative infinity to positive infinity (∫[-∞, ∞] (x²)dx):

For this case, we evaluate the limits of the integral at the boundaries:

∫[-∞, ∞] (x²)dx = lim┬(a→-∞)⁡〖(1/3)x³ 〗-lim┬(b→∞)⁡〖(1/3)x³ 〗.

As x³ grows without bound as x approaches either positive or negative infinity, both limits diverge to infinity. Therefore, the integral from negative infinity to positive infinity (∫[-∞, ∞] (x²)dx) diverges.

Case 2: Integrating from a finite value to positive infinity (∫[a, ∞] (x²dx):

For this case, we evaluate the limits of the integral at the boundaries:

∫[a, ∞] (x²)dx = lim┬(b→∞)⁡〖(1/3)x² 〗-lim┬(a→a)⁡〖(1/3)x² 〗.

The first limit diverges to infinity as x^3 grows without bound as x approaches infinity. However, the second limit evaluates to a finite value of (1/3)a², as long as a is not negative infinity.

Hence, if a is a finite value, the integral from a to positive infinity (∫[a, ∞] (x²)dx) diverges.

In summary, the improper integral of ∫(x²)dx diverges, regardless of whether it is integrated from negative infinity to positive infinity or from a finite value to positive infinity.

To linearize the given differential equations, we need to find the linear approximation of the nonlinear terms. In the first equation, the linearization involves finding the first derivative of y with respect to t, while in the second equation, we use logarithmic differentiation to linearize the nonlinear term. In both cases, the linearized equations help approximate the behavior of the original nonlinear equations.

a) To linearize the equation dy/dt + zy = r, we can write the linearized equation as d(y - y0)/dt + z(y - y0) = r - r0, where y0 and r0 are the values of y and r at a specific point. This linearization approximates the behavior of the original equation around the point (y0, r0). The linearization involves finding the first derivative of y with respect to t.

b) To linearize the equation dy/dt + ay + By^2 + yln(y) = Q, we can use logarithmic differentiation. Taking the natural logarithm of both sides of the equation, we get ln(dy/dt) + ln(y) + ln(a) + ln(B) + yln(y) = ln(Q). Then, we differentiate both sides with respect to t, resulting in 1/(y^2) * (dy/dt) + (1/y) * (dy/dt) + (1/y) * y + 0 + yln(y) * (dy/dt) = 0. This linearization allows us to approximate the behavior of the original nonlinear equation by neglecting higher-order terms.

The stockout probability is extremely small, as the z-score of 7.22 corresponds to a very high demand compared to the available stock.

What is probability?

Probability is a fundamental concept in mathematics and statistics that quantifies the likelihood of an event occurring. It represents a numerical measure between 0 and 1, where 0 indicates an event is impossible, and 1 denotes the event is certain to happen.

Given:

Mean demand per period[tex](\(\mu\))[/tex] = 50

Standard deviation of demand per period[tex](\(\sigma\))[/tex]= 6

Order-up-to level [tex](\(S\)) = 225[/tex]

Lead time [tex](\(L\)) = 3 periods[/tex]

We can calculate the demand during the lead time as follows:

Mean demand during the lead time: [tex]\(\mu_L = \mu \times L\)[/tex]

Standard deviation of demand during the lead time:[tex]\(\sigma_L = \sigma \times \sqrt{L}\)[/tex]

Substituting the given values, we have:

[tex]\(\mu_L = 50 \times 3 = 150\)\(\sigma_L = 6 \times \sqrt{3} \approx 10.39\)[/tex]

To calculate the stockout probability, we need to compare the demand during the lead time to the available stock. Since the demand follows a Normal distribution, we can use the z-score formula:

[tex]\(z = \frac{S - \mu_L}{\sigma_L}\)[/tex]

where \(S\) is the order-up-to level.

Substituting the values, we have:

[tex]\(z = \frac{225 - 150}{10.39} \approx 7.22\)[/tex]

Since the partial derivatives are equal, the equation is exact.

To find the solution, we integrate the coefficient of dx with respect to x and the coefficient of dy with respect to y. Integrating [tex]4x^2 - 2xy + 5[/tex] with respect to x gives [tex](4/3)x^3 - x^2y + 5x + g(y)[/tex], where g(y) is the constant of integration with respect to x.

a)The actual additional cost of producing the 21st food processor is $29.50.

b) Using the marginal cost approximation, the cost of producing the 21st food processor is $2,830.

a) To find the actual additional cost of producing the 21st food processor, we need to calculate the difference between the total cost of producing 21 processors and the total cost of producing 20 processors.

The total cost of producing x food processors is given by C(x) = 2,000 + 50x - 0.5x^2.

To find the cost of producing the 20th processor, we substitute x = 20 into the cost equation:

C(20) = 2,000 + 50(20) - 0.5(20)^2

= 2,000 + 1,000 - 0.5(400)

= 2,000 + 1,000 - 200

= 3,000 - 200

= 2,800

Now, we calculate the cost of producing the 21st processor:

C(21) = 2,000 + 50(21) - 0.5(21)^2

= 2,000 + 1,050 - 0.5(441)

= 2,000 + 1,050 - 220.5

= 3,050 - 220.5

= 2,829.5

The actual additional cost of producing the 21st food processor is the difference between C(21) and C(20):

Additional cost = C(21) - C(20)

= 2,829.5 - 2,800

= 29.5

Therefore, the actual additional cost of producing the 21st food processor is $29.50.

b) To approximate the cost of producing the 21st food processor using marginal cost, we need to find the derivative of the cost function with respect to x.

C'(x) = 50 - x

The marginal cost represents the rate of change of the total cost with respect to the number of units produced. So, to approximate the cost of producing the 21st processor, we evaluate the derivative at x = 20 (since the 20th processor has already been produced).

Marginal cost at x = 20:

C'(20) = 50 - 20

= 30

The marginal cost is $30 per unit. Since we are interested in the cost of producing the 21st food processor, we can approximate it by adding the marginal cost to the cost of producing the 20th processor.

Approximated cost of producing the 21st food processor = Cost of producing the 20th processor + Marginal cost

= C(20) + C'(20)

= 2,800 + 30

= 2,830

Therefore, using the marginal cost approximation, the cost of producing the 21st food processor is $2,830.

The x-intercept(s) and y-intercept of the given conic section r = 1 + sin(θ) are not applicable. The conic section does not intersect the x-axis or the y-axis.

The equation of the given conic section is r = 1 + sin(θ), where r represents the distance from the origin to a point on the curve and θ is the angle between the positive x-axis and the line connecting the origin to the point. In polar coordinates, the x-intercept occurs when r equals zero, indicating that the curve intersects the x-axis. However, in this case, since r = 1 + sin(θ), it will never be equal to zero. Similarly, the y-intercept occurs when θ is either 0° or 180°, but sin(0°) = 0 and sin(180°) = 0, so the curve does not intersect the y-axis either.

The derivatives of the functions are:

A) y = 93x is dy/dx = 93.

B) y = ln(3x² + 2x + 1) is dy/dx = (6x + 2)/(3x² + 2x + 1).

C)  y = x²e⁽⁴ˣ⁾ is dy/dx = 2xe⁽⁴ˣ⁾ + 4x²e⁽⁴ˣ⁾

D) y = e(sin(3x)) is dy/dx = 3e(sin(3x))cos(3x).

E) y = 8 + 3x is dy/dx = 3.

A) For the function y = 93x, we use the power rule to find the derivative:

The power rule states that if we have a function of the form y = cxⁿ, where c and n are constants, the derivative is given by dy/dx = cnx⁽ⁿ⁻¹⁾.

So, c = 93 and n = 1.

Applying the power rule:

dy/dx = 1 * 93 * x⁽¹⁻¹⁾ = 93 * x⁰ = 93.

Therefore, the derivative of y = 93x is dy/dx = 93.

B) Function y = ln(3x² + 2x + 1):

Here, use the chain rule. The chain rule states that for a composition of functions, y = f(g(x)), the derivative is dy/dx = f'(g(x)) * g'(x).

f(u) = ln(u) and g(x) = 3x² + 2x + 1.

The derivative of f(u) = ln(u) with respect to u is 1/u.

To find g'(x), we differentiate each term separately:

g'(x) = d/dx (3x²) + d/dx (2x) + d/dx (1) = 6x + 2 + 0 = 6x + 2.

Next, we apply the chain rule:

dy/dx = f'(g(x)) * g'(x) = (1/(3x² + 2x + 1)) * (6x + 2).

Therefore, the derivative of y = ln(3x² + 2x + 1) is dy/dx = (6x + 2)/(3x² + 2x + 1).

C) function y = x²e⁽⁴ˣ⁾:

We use the product rule to find its derivative.

The product rule says for a function of the form y = f(x)g(x), the derivative is given by dy/dx = f'(x)g(x) + f(x)g'(x).

Here, f(x) = x² and g(x) = e⁽⁴ˣ⁾. The derivative of f(x) = x² with respect to x is 2x.

To find g'(x), we differentiate e⁽⁴ˣ⁾ using the chain rule.

The derivative of [tex]e^{u}[/tex] with respect to u is [tex]e^{u}[/tex].

g'(x) = d/dx (e⁽⁴ˣ⁾) = e⁽⁴ˣ⁾) * d/dx (4x) = 4e⁽⁴ˣ⁾.

Apply the product rule:

dy/dx = f'(x)g(x) + f(x)g'(x) = 2x * e⁽⁴ˣ⁾ + x² * 4e⁽⁴ˣ⁾.

Thus, the derivative of y = x²e⁽⁴ˣ⁾ is dy/dx = 2xe⁽⁴ˣ⁾ + 4x²e⁽⁴ˣ⁾.

D) Function y = e(sin(3x)):

We use the chain rule here: It states that for a function y = f(g(x)), the derivative is dy/dx = f'(g(x)) * g'(x).

So, f(u) = [tex]e^{u}[/tex] and g(x) = sin(3x).

The derivative of f(u) = [tex]e^{u}[/tex] with respect to u is [tex]e^{u}[/tex].

To find g'(x), we differentiate sin(3x:.

The derivative of sin(u) with respect to u is cos(u), and the derivative of 3x with respect to x is 3.

g'(x) = d/dx (sin(3x)) = cos(3x) * d/dx (3x) = 3cos(3x).

Let's, apply the chain rule:

dy/dx = f'(g(x)) * g'(x) = e(sin(3x)) * 3cos(3x).

So, the derivative of y = e(sin(3x)) is dy/dx = 3e(sin(3x))cos(3x).

E) y = 8 + 3x:

We use the power rule to find the derivative:

y = cxⁿ, where c and n are constants, and the derivative is dy/dx = cnx⁽ⁿ⁻¹⁾.

In this case, c = 3 and n = 1.

Apply the power rule:

dy/dx = 1 * 3 * x⁽¹⁻¹⁾ = 3 * x⁰ = 3.

Therefore, the derivative of y = 8 + 3x is dy/dx = 3.

Answer:

Step-by-step explanation:

The limiting value of the population is 1000.to determine the time at which the population will be equal to one half of the limiting value, we need to solve for t in the equation p(t) = 0.

to find the limiting value of the population, we need to determine the value that p(t) approaches as t approaches infinity. in this case, we can find the limiting value by setting dp/dt equal to zero and solving for p.

given: dp/dt = p(10⁽⁻²⁾ – 10⁽⁻⁵⁾p)

setting dp/dt = 0, we have:p(10⁽⁻²⁾ – 10⁽⁻⁵⁾p) = 0

from this equation, we can see that either p = 0 or (10⁽⁻²⁾ – 10⁽⁻⁵⁾p) = 0.

if p = 0, then it remains zero and does not change. however, this would not be a meaningful limiting value for the population.

to find the non-zero limiting value, we solve (10⁽⁻²⁾ – 10⁽⁻⁵⁾p) = 0:

10⁽⁻²⁾ – 10⁽⁻⁵⁾p = 010⁽⁻²⁾ = 10⁽⁻⁵⁾p

p = 10⁽⁻²⁾/10⁽⁻⁵⁾p = 10³

p = 1000 5 * 1000 = 500.

given: dp/dt = p(10⁽⁻²⁾ – 10⁽⁻⁵⁾p), p(0) = 20

we can solve this differential equation to find the population function p(t), then solve for t when p(t) = 500.

however, since the specific solution to the differential equation is not provided, we are unable to calculate the exact time at which the population will be equal to one half of the limiting value without further information or the solution to the differential equation.

First, we find the derivative of f(x) using the chain rule and quotient rule:

f'(x) = 1 - 10sec²tan¹x * 1/(1+x²)

f'(x) = (1-x²-10tan²tan¹x)/(1+x²)

To find critical points, we set f'(x) = 0 and solve for x:

1-x²-10tan²tan¹x = 0

tan²tan¹x = (1 - x²)/10

tan¹x = √((1 - x²)/10)

x = tan(√((1 - x²)/10))

Using a graphing calculator, we can see that there is only one critical point located at x = 0.707.

Next, we determine the intervals of increase and decrease using the first derivative test and the critical point:

Interval (-∞, 0.707): f'(x) &lt; 0, f(x) is decreasing

Interval (0.707, ∞): f'(x) &gt; 0, f(x) is increasing

Since there is only one critical point, it must be a local extremum. To determine whether it is a maximum or minimum, we use the second derivative test:

f''(x) = (2x(2 - x²))/((1 + x²)³)

f''(0.707) = -2.67, therefore x = 0.707 is a local maximum.

In summary, the critical point is located at x = 0.707 and it is a local maximum. The function is decreasing on the interval (-∞, 0.707) and increasing on the interval (0.707, ∞).

Homogeneous solution: Characteristic equation is r^2 - 5r - 6 = 0. Solving, roots r1 = -1 and r2 = 6. The homogeneous solution is given by y_h(t) = C1e^(-t) + C2e^(6t), where C1 and C2 are constants.

Particular solution: y_p(t) = At^2e^t. Plug this into the differential equation and solve for A:

y_p''(t) - 5y_p'(t) - 6y_p(t) = tet

2Ae^t - 5(2Ate^t + At^2e^t) - 6(At^2e^t) = tet

2Ae^t - 10Ate^t - 5At^2e^t - 6At^2e^t = tet

(2A - 10At - 11At^2)e^t = tet

Comparing the coefficients of te^t and t^2e^t on both sides, we get:

2A - 10At - 11At^2 = t and 0 = t

Solving the first equation, we find A = -1/11 and substituting this value into the particular solution, we have:

y_p(t) = (-1/11)t^2e^t

Therefore, Particular solution is y_p(t) = (-1/11)t^2e^t.

Homogeneous solution: Characteristic equation is r^2 + 2r + 3 = 0. Solving, r1 = -1 + i√2 and r2 = -1 - i√2. y_h(t) = e^(-t)[C1cos(√2t) + C2sin(√2t)], where C1 and C2 are constants.

Particular solution: y_p(t) = Acos(5t) + Bsin(5t). Plug this:

y_p''(t) + 2y_p'(t) + 3y_p(t) = 4cos(5t)

-25Acos(5t) - 25Bsin(5t) + 10Asin(5t) - 10Bcos(5t) + 3Acos(5t) + 3Bsin(5t) = 4cos(5t)

Comparing the coefficients of cos(5t) and sin(5t) on both sides, we get:

-25A + 10A + 3A = 4 and -25B - 10B + 3B = 0

Solving, A = 4/18 = 2/9 and B = 0. Substituting, we have:

Particular solution: y_p(t) = At^3 + Bt^2 + Ct + De^t. Plug this into the differential equation and solve for A, B, C, and D:

y_p''(t) - y_p'(t) = 3t^2 + tsin(3t) - 4te^t

6A + 2B - C + De^t = 3t^2 + tsin(3t) - 4te^t

Comparing the coefficients of t^3, t^2, t, and e^t on both sides, we get:

6A = 0, 2B - C = 0, 0 = 3t^2 - 4t, and 0 = t*sin(3t)

A = 0. Substituting, we have 2B - C = 0, which implies C = 2B. The third equation represents a polynomial equation that can be solved to find t = 0 and t = 4/3 as roots. Therefore, t = 0 and t = 4/3 satisfy this equation. Substituting these values into the fourth equation, we find 0 = 0 and 0 = 0, which are satisfied for any value of t.

Hence, Particular solution is y_p(t) = 0.

(d) y" + 10y' + 25y = te^(-5t) + 2t + sinh(t)

Homogeneous solution: Characteristic equation is r^2 + 10r + 25 = 0. Solving, r1 = -5 and r2 = -5. Homogeneous solution y_h(t) = (C1 + C2t)e^(-5t), where C1 and C2 are constants.

Particular solution: y_p(t) = At + B + Cte^(-5t) + Dt^2e^(-5t). Plug this into the differential equation and solve for A, B, C, and D:

y_p''(t) + 10y_p'(t) + 25y_p(t) = te^(-5t) + 2t + sinh(t)

2D - 10Dt + Cte^(-5t) - 5Cte^(-5t) + 10Cte^(-5t) - 10B - 5At + 25At + 25B = te^(-5t) + 2t + sinh(t)

Comparing the coefficients of te^(-5t), t, and 1 on both sides, we get:

2D + C = 1, -10D - 5A = 2, and -10B + 25A = sinh(t)

To solve for A, B, C, and D, we need additional information about the non-homogeneous term for t.

(e) y + 4y' + 5y = 4e^(-2t) - e^t*cos(t) - te^(-2t)*sin(t)

Homogeneous solution: Characteristic equation is r + 4r + 5 = 0. Solving this equation, we find the roots r1 = -2 + i and r2 = -2 - i. The homogeneous solution is given by y_h(t) = e^(-2t)[C1cos(t) + C2sin(t)], where C1 and C2 are constants.

Particular solution: y_p(t) = Ae^(-2t) + Bcos(t) + Csin(t) + Dt^2e^(-2t) + Et^2cos(t) + Ft^2sin(t). Plug this into the differential equation and solve for A, B, C, D, E, and F:

Comparing the coefficients of e^(-2t), cos(t), sin(t), t^2e^(-2t), t^2cos(t), and t^2*sin(t) on both sides, we get:

Solving these equations, we find A = -1, B = -1/2, C = 0, D = 1/2, E = -1/2, and F = 0. Substituting these values into the particular solution, we have:

y_p(t) = -e^(-2t) - (1/2)*cos(t) + (1/2)t^2e^(-2t) - (1/2)t^2cos(t)

Therefore, Particular solution is y_p(t) = -e^(-2t) - (1/2)*cos(t) + (1/2)t^2e^(-2t) - (1/2)t^2cos(t).

the total distance traveled by the particle over the time period is 14/3 meters.

To find the displacement of the particle over the time period, we need to integrate the velocity function v(t) over the given interval.

A) Displacement:

The displacement is given by the definite integral of the velocity function v(t) over the interval [1, 6]:

Displacement = ∫[1, 6] (t^2 - 2t - 8) dt

To evaluate this integral, we can use the power rule of integration:

Displacement = [(1/3) * t^3 - t^2 - 8t] evaluated from 1 to 6

= [(1/3) * (6^3) - 6^2 - 8 * 6] - [(1/3) * (1^3) - 1^2 - 8 * 1]

= [72 - 36 - 48] - [1/3 - 1 - 8]

= -12 - (-22/3)

= -12 + 22/3

= (-36 + 22)/3

= -14/3

Therefore, the displacement of the particle over the time period is -14/3 meters.

B) Total Distance:

To find the total distance traveled by the particle over the time period, we need to consider the absolute value of the velocity function and integrate it over the interval [1, 6]:

Total Distance = ∫[1, 6] |t^2 - 2t - 8| dt

Since the velocity function is already non-negative for the given interval, we can calculate the total distance by evaluating the integral of v(t) directly:

Total Distance = ∫[1, 6] (t^2 - 2t - 8) dt

Using the same integral from part A, we can evaluate it as:

Total Distance = (-14/3) meters
