Answer:

The sum of 33, 78, 23, 21, 98, and 32 is 325.

Answer:

6 m, 24 m

Step-by-step explanation:

area of kite = (diagonal 1 × diagonal 2) / 2

Let the length of the shorter diagonal = x.

The length of the longer diagonal is 4x.

The area is the product of the diagonals divided by 2.

area = 4x × x / 2 = 4x²/2 = 2x²

The area is 72 m².

Therefore, 2x² must equal 72 m².

2x² = 72 m²

Divide both sides by 2.

x² = 36 m²

Take the square root of both sides.

x = 6 m

The short diagonal has length 6 m.

The long diagonal is 4x long.

4x = 4(6 m) = 24 m

Answer: 6 m, 24 m

Answer:

6 metres and 24 metres

Step-by-step explanation:

The kite will be composed of two smaller triangles and two larger triangles.

Let's call the shorter diagonal (across the kite) W.

So the longer diagonal (top to bottom of kite) will be 4W.

area = (L X W)/2

= (4W X W)/2

= 4W²/2

= 2W².

2W² = 72

W² = 36

W = 6 metres.

so the shorter diagonal is 6 metres.

the longer diagonal is 4 X 6 = 24 metres

It will take approximately 2.32 hours to fill 11 tanks.

First, we need to convert the capacity of the tanks from gallons to liters, as the rate at which we empty the bottle is given in liters. Since 1 gallon is equal to 3.8 liters, the capacity of each tank is 50 gallons * 3.8 liters/gallon = 190 liters.

Now, let's calculate the time it takes to fill one tank:

The bottle is emptied at a rate of 2 liters every 8 seconds. To find the time it takes to fill one tank, we divide the capacity of the tank (190 liters) by the rate at which we empty the bottle (2 liters/8 seconds):

Time for one tank = 190 liters / (2 liters/8 seconds) = 190 liters * (8 seconds/2 liters) = 760 seconds.

Next, we need to find the total time required to fill 11 tanks. Since each tank takes 760 seconds to fill, we multiply this by 11 to account for the 11 tanks:

Total time to fill 11 tanks = 760 seconds/tank * 11 tanks = 8,360 seconds.

Finally, we convert the total time from seconds to hours. There are 60 seconds in a minute and 60 minutes in an hour, so:

Total time to fill 11 tanks = 8,360 seconds * (1 minute/60 seconds) * (1 hour/60 minutes) = 2.32 hours (rounded to two decimal places).

Therefore, it will take approximately 2.32 hours to fill 11 tanks.

Using binomial probability, the probability is 0.8897

Using binomial probability formula, we can determine the number of defective batteries

In this case, n = 1,200 (the sample size) and p = 0.006 (the probability of finding a defective battery).

We want to find the probability of finding 5 or fewer defective batteries, which is equivalent to finding the cumulative probability up to 5.

Let's calculate this probability:

P(X ≤ 5) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4) + P(X = 5)

Using the binomial probability formula:

[tex]P(X = k) = C(n, k) * p^k * (1 - p)^(^n ^- ^k^)[/tex]

where C(n, k) represents the number of combinations of n items taken k at a time.

Plugging the values and solving;

P(X ≤ 5) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4) + P(X = 5) =

[tex]C(1200, 0) * 0.006^0 * (1 - 0.006)^(^1^2^0^0 ^- ^0^)\\+ C(1200, 1) * 0.006^1 * (1 - 0.006)^(^1^2^0^0 ^- ^1^)\\+ C(1200, 2) * 0.006^2 * (1 - 0.006)^(1^2^0^0 ^- ^2^)\\+ C(1200, 3) * 0.006^3 * (1 - 0.006)^(^1^2^0^0 ^- ^3)\\+ C(1200, 4) * 0.006^4 * (1 - 0.006)^(^1^2^0^0 ^- ^4)\\+ C(1200, 5) * 0.006^5 * (1 - 0.006)^(^1^2^0^0 ^- ^5^)[/tex]

To calculate these probabilities, we need to use a combination formula to determine the number of combinations. The combination formula is given by:

C(n, k) = n! / (k! * (n - k)!)

Now let's calculate the probability:

[tex]P(X \leq 5) = \\C(1200, 0) * 0.006^0 * (1 - 0.006)^(^1^2^0^0 ^- ^0^)\\+ C(1200, 1) * 0.006^1 * (1 - 0.006)^(^1^2^0^0 ^- ^1^)\\+ C(1200, 2) * 0.006^2 * (1 - 0.006)^(^1^2^0^0 ^- ^2^)\\+ C(1200, 3) * 0.006^3 * (1 - 0.006)^(^1^2^0^0 ^- ^3^)\\+ C(1200, 4) * 0.006^4 * (1 - 0.006)^(^1^2^0^0 ^- ^4^)\\+ C(1200, 5) * 0.006^5 * (1 - 0.006)^(^1^2^0^0 ^- ^5^)[/tex]

Angle C of the triangle measures 40°.

Side AC = 18.84

Side AB= 25.79

Given triangle,

∠A = 112°

∠B = 28°

BC = 37

Now,

Sum of all the interior angles of triangle is 180.

So,

∠A + ∠B +∠C = 180°

112° + 28° + ∠C = 180°

∠C = 40°

Now,

According to sine rule,

Ratio of side length to the sine of the opposite angle is equal.

Thus,

a/SinA = b/SinB = c/SinC

Let,

BC = a

AC = b

AB = c

So,

a/Sin112 = b/Sin28 = c/Sin40

37/0.921 = b/0.469 = C/0.642

Answer:

$3827.00

Step-by-step explanation:

To calculate the total compound amount at the end of six years with an interest rate of 1.5% compounded annually, we can use the formula for compound interest:

A = P * (1 + r/n)^(n*t)

Where:

A = Total compound amount

P = Principal amount (initial investment)

r = Annual interest rate (as a decimal)

n = Number of times interest is compounded per year

t = Number of years

In this case:

P = $3500

r = 1.5% = 0.015 (as a decimal)

n = 1 (compounded annually)

t = 6 years

Substituting these values into the formula, we have:

A = 3500 * (1 + 0.015/1)^(1*6)

Calculating this expression, we get:

A ≈ 3500 * (1.015)^6 ≈ 3500 * 1.093717 ≈ 3827.00

Rounding the total compound amount to 2 decimal places, the final value is approximately $3827.00

The distance between the side AB are 314.2 ft.

In a triangle ABC AC = 200 ft, m ∠A = 72°, and m ∠B = 37°. we need to find the measure of the side AB,

So,

Using sine law.

Sin A / CB = Sin B / AC = Sin C / AB

Using the angle sum property of a triangle we find the value of angle C,

∠C = 180° - (∠A + ∠B)

∠C = 180° - (72° + 37°)

∠C = 180° - 109°

∠C = 71°

So,

Sin 37° / 200 = Sin 71° / AB

AB = 200 / Sin 37° × Sin 71°

AB = 314.2 ft

Hence the distance between the side AB are 314.2 ft.

The Domain of the function would be the interval [0, 6].The increasing interval represents the point where the company is pricing the pens appropriately, resulting in increasing profit.Average rate of change = (f(5) - 120) / (5 - 3)

Part A:

The x-intercepts of the graph, located at the ordered pairs (0, 0) and (6, 0), represent the points where the profit function intersects the x-axis. In the context of the problem, these x-intercepts indicate the price values at which the company sells pens, resulting in zero profit. When the price is $0, the company does not make any profit, and when the price is $6, the company also does not make any profit. The x-intercepts represent the break-even points where the company covers its costs but does not generate any profit.

The maximum value of the graph, located at the vertex (3, 120), represents the peak profit achieved by the company. The vertex is the highest point on the graph and indicates the optimal price at which the company can maximize its profit. In this case, when the price of pens is $3, the company achieves a maximum profit of $120.

Regarding the intervals of increasing and decreasing profit, the function is decreasing to the left of the vertex (3, 120) and increasing to the right of the vertex. This means that for prices less than $3, the profit decreases, and for prices greater than $3, the profit increases. The decreasing interval represents the point where the company is pricing the pens too low, resulting in decreasing profit. The increasing interval represents the point where the company is pricing the pens appropriately, resulting in increasing profit.

Part B:

To find the approximate average rate of change of the graph from x = 3 to x = 5, we need to calculate the slope of the line segment connecting the two points. The average rate of change represents the average amount by which the profit changes per unit increase in price over the given interval.

Using the coordinates (3, 120) and (5, f(5)) on the graph, we can determine the change in profit and price:

Change in profit = f(5) - 120

Change in price = 5 - 3

Substituting the values of the points into the equation, we can calculate the approximate average rate of change:

Average rate of change = (f(5) - 120) / (5 - 3)

Part C:

The constraints of the domain refer to the limitations or restrictions on the values that x (the price of pens) can take. Based on the given information, the x-intercepts of the graph are at (0, 0) and (6, 0), indicating that the price cannot be negative or exceed $6. Therefore, the domain of the function would be the interval [0, 6]. The constraint is that the price of the pens must be within this range for the profit function to be applicable.

For all points (x, h(x)), h(x) exists if and only if x - 4≥0

The graph of h(x) intercepts the x-axis at (4, 0).

The domain of h(x) is the set of all real numbers since there are no restrictions on the input variable x.

For all points (x, h(x)), h(x) exists if and only if x - 4 ≥ 0. This is because the cube root function is only defined for non-negative values, and the expression inside the cube root, x - 4, must be non-negative for h(x) to exist.

The graph of h(x) intercepts the x-axis at (4, 0) since plugging in x = 4 into the equation gives h(4) = ∛(4-4) = ∛0 = 0. This means that the point (4, 0) lies on the graph.

Taking the logarithm of both sides of [tex]\large\sf\:3^a = 9^b\\[/tex], we get:

[tex]\large\sf\:\log_3(3^a) = \log_3(9^b)\\[/tex]

Applying the power rule of logarithms, we can bring down the exponents:

[tex]\large\sf\:a\log_3(3) = b\log_3(9)\\[/tex]

Since [tex]\large\sf\:\log_3(3) = 1[/tex] and [tex]\large\log_3(9) = 2\\[/tex], we simplify to:

[tex]\large\sf\:a = 2b\\[/tex] ---- (1)

Similarly, taking the logarithm of both sides of [tex]\sf\:9^b = 27^c\\[/tex], we get:

[tex]\large\sf\:b\log_3(9) = c\log_3(27)\\[/tex]

Using the values of [tex]\sf\:\log_3(9)\\[/tex] and [tex]\sf\:\log_3(27)\\[/tex] as before, we have:

[tex]\large\sf\:b(2) = c(3)\\[/tex]

Now, let's substitute the value of b from equation (1) into equation (2):

[tex]\large\sf\:2(2b) = 3c\\[/tex]

[tex]\large\sf\:4b = 3c\\[/tex]

Rearranging, we find:

[tex]\large\sf\:c = \frac{4b}{3}\\[/tex] ---- (3)

We now have expressions for a, b, and c in terms of b. Let's substitute these into the expression [tex]\large\sf\:\frac{a}{b} + \frac{b}{c} + \frac{c}{a}\\[/tex]:

[tex]\large\sf\:\frac{a}{b} + \frac{b}{c} + \frac{c}{a} = \frac{2b}{b} + \frac{b}{\frac{4b}{3}} + \frac{\frac{4b}{3}}{2b}\\[/tex]

Simplifying further, we get:

[tex]\large\sf\:\frac{2}{1} + \frac{3}{4} + \frac{2}{3}\\[/tex]

Finding the common denominator and combining the fractions, we have:

The trigonometric ratios is concerned with the relationship of an angle of a right-angled triangle to ratios of two side lengths.

The basic trigonometric ratios includes;

sine, cosine and tangent.

recall that sin60° = √3/2 and sin30° = 1/2

sin 60° = m/(24√3) {opposite/hypotenuse}

√3/2 = m/(24√3)

m = (24√3 × √3)/2 {cross multiplication}

To find the missing angle and side measures of ΔABC, we can use the properties of a triangle.

Given:

∠A = 50°

∠C = 90°

CB = 16

We can start by finding the measure of ∠B:

∠A + ∠B + ∠C = 180° (Sum of angles in a triangle)

50° + ∠B + 90° = 180°

∠B + 140° = 180°

∠B = 180° - 140°

∠B = 40°

Now, using Sine law

CB/ sin A = AB / sin C

16 / sin 50 = AB / sin 90

16 / 0.766044 = AB

AB = 12.25

Again 12.25 = AC/ sin B

probability = 38/93 = 0.409

For p(pass or did study):

possible outcome = 29

sample size = 93

probability = 29/93 = 0.312

For p(fail and pass):

p(fail) = 26/93

p(pass) = 67/93

probability = 26/93× 67/93

= 1742/8649

= 0.201

For p(pass or fail);

P(pass) = 67/93

P(fail) = 26/93

Probability of pass or fail = 67/93+26/93

= 93/93 = 1
