Frazer is planning to paint one of his walls and needs to know if he has purchased enough paint to cover the wall. One pot of paint, which covers 100 square feet, will not be enough to cover Frazer's wall, which measures 14 feet by 8 feet. He will need to purchase at least two pots of paint to fully cover the wall.

To calculate the total square footage of the wall, we need to multiply the length by the width. Therefore, the wall's total square footage is 14 x 8 = 112 square feet.

Next, we need to determine if a pot of paint, which covers 100 square feet, will be enough to cover the wall. To do this, we can divide the wall's total square footage by the amount of square footage a pot of paint covers.

112 / 100 = 1.12

This means that Frazer will need more than one pot of paint to fully cover the wall.

Answer:

138 feets

Step-by-step explanation:

Given that :

Angle of depression (α) = 16°

Elevation = height = 450 feets

Appling trigonometry :

From the picture attached :

Height / elevation = 450 feets (Adjacent)

Distance = d (opposite)

Tan α = opposite / Adjacent

Tan 17 = d / 450

450 tan17 = d

450 * 0.3057306 = d

d = 137.57880

Hence, distance between a point on the ground directly below the helicopter and the landing pad 138 feets

The distance between a point on the ground directly below the helicopter and the landing pad is 129.03 feet.

Given that,

The helicopter is flying at an elevation of 450 feet.

It is within sight of the landing pad and the pilot finds that the angle of depression to the landing pad is 16∘.

We have to determine,

The distance between a point on the ground directly below the helicopter and the landing pad.

According to the question,

The angle of depression =  16°,

Elevation = height = 450 feet

And d is the distance,

The angle of depression is an important component used in trigonometric operations.

The angle of depression is formed when the observer stands on a ground higher than the object which he is trying to observe.

Therefore, The angle of depression is,

\(Tan16 = \dfrac{d}{450}\\\\0.28 = \dfrac{d}{450}\\\\d = 450 \times 0.28\\\\d = 129.03 \ feet\)

Hence, The distance between a point on the ground directly below the helicopter and the landing pad is 129.03 feet.

5 cm or 29 cm

Step-by-step explanation:

Let x length is cut off from each measurements.

Thus, the new measurements would be: 20 - x, 41 - x, 44 - x, which forms the sides of a right triangle.

Here, (44 - x) will be hypotenuse and (20 - x) and (41 - x) will be perpendicular legs of the triangle.

Therefore, by Pythagoras theorem:

\( {(41 - x)}^{2} + {(20 - x)}^{2} = {(44 - x)}^{2} \\ \\ \therefore \: {(41)}^{2} - 82x + {x}^{2} + {(20)}^{2} - 40x + {x}^{2} \\ = {(44)}^{2} - 88x + {x}^{2} \\ \\ \therefore \: 1681 - 122x + 2 {x}^{2} + 400 \\ = 1936 - 88x + {x}^{2} \\ \\ \therefore \: 2081 - 122x + {x}^{2} = 1936 - 88x \\ \\ \therefore \: {x}^{2} - 122x + 88x + 2081 - 1936 = 0 \\ \\ \therefore \: {x}^{2} - 34x + 145 = 0 \\ \\ \therefore \: {x}^{2} - 29x - 5x+ 145 = 0 \\ \\ \therefore \: x(x - 29) - 5(x - 29) = 0 \\ (x - 5)(x - 29) = 0 \\ x - 5 = 0 \: or \: x - 29 = 0 \\ \\ \therefore \: x = 5, \: 29\)

Answer:

\(y = \frac{3}{5} x - \frac{38}{5} \)

Step-by-step explanation:

\(y = mx + b\)

\(m = \frac{y2 - y1}{x2 - x1} \)

\(m = \frac{ - 4 - - 7}{6 - 1} \)

\(m = \frac{3}{5} \)

substitute any coordinate pair into y= mx + b

I chose (1,-7)

\( - 7 = \frac{3}{5} \: (1)+ b\)

\(b = - 7 - \frac{3}{5} \)

\(b = - \frac{38}{5} \)

Marginal Effect for 75-year-old: -543.32 4. Age at which wealth is maximized: 70.55 years 5. Maximum wealth: 742,752.24
1. To find the marginal effect formula in Model 2, we'll take the derivative of the wealth equation with respect to age:

Marginal Effect = d(Wealth)/d(Age) = 10,400.1241 - (2 * 73.7597 * Age)

So the formula for the marginal effect is:
Marginal Effect = 10,400.1241 - 147.5194 Age

2. To calculate the marginal effect for a 50-year-old:
Marginal Effect = 10,400.1241 - (147.5194 * 50)
Marginal Effect ≈ 3,225.11

3. To calculate the marginal effect for a 75-year-old:
Marginal Effect = 10,400.1241 - (147.5194 * 75)
Marginal Effect ≈ -543.32

4. To find the age at which wealth is maximized, set the marginal effect to zero and solve for age:
0 = 10,400.1241 - 147.5194 Age
Age ≈ 70.55 years

5. To find the maximum wealth, plug the age at which wealth is maximized (70.55 years) back into Model 2:
Wealth = 4,265.20 + 10,400.1241 * 70.55 - 73.7597 * (70.55)^2
Wealth ≈ 742,752.24

Your answer:
1. Marginal Effect = 10,400.1241 - 147.5194 Age
2. Marginal Effect for 50-year-old: 3,225.11
3. Marginal Effect for 75-year-old: -543.32
4. Age at which wealth is maximized: 70.55 years.

Answer:

no the triangles are not similar.

Step-by-step explanation:

To find the local maximum and minimum values of the function\(f(x) = x^2 - 3x + 4\)using the second derivative test, we need to follow these steps:

Find the first derivative of f(x):

\(f'(x) = 2x - 3\)

Find the second derivative of f(x):

\(f''(x) = 2\)

Since the second derivative is a constant (2), it does not change sign. Therefore, we cannot apply the second derivative test to determine the nature of the critical points.

To find the local maximum and minimum values, we need to consider the critical points. Critical points occur where the first derivative is equal to zero or undefined.

Setting f'(x) = 0:

\(2x - 3 = 0\\2x = 3\\x = 3/2\)

The critical point is\(x = 3/2.\)

To determine whether it is a local maximum or minimum, we can consider the concavity of the function. Since the second derivative is positive (2), it indicates that the function is concave up everywhere.

Since we have a concave-up function, the critical point\(x = 3/2\)corresponds to a local minimum.

Therefore, the local minimum value of \(f(x) = x^2 - 3x + 4\) is achieved at x = 3/2.

324π in²

Step-by-step explanation:

The surface area of a sphere = 4πr² ( r is the radius )

Calculate r using the volume (V) formula

V = \(\frac{4}{3}\)πr³

Here V = 972π , thus

\(\frac{4}{3}\)πr³ = 972π ( divide both sides by π )

\(\frac{4}{3}\)r³ = 972 ( multiply both sides by 3 to clear the fraction )

4r³ = 2916 ( divide both sides by 4 )

r³ = 729 ( take the cube root of both sides )

r = \(\sqrt[3]{729}\) = 9

Thus

surface area = 4π × 9² = 4π × 81 = 324π in²

It will take 50.7 seconds to fill the ball to a radius of 15 centimeters.

The ball will be filled when its radius is r = 15cm, then the ball will be filled when the volume is equal to:

V = (4/3)*3.14*(15 cm)³

V = 14,130 cm³

We know that the ball has already 5,000 cm³ of air in it, so the amount of air missing is:

14,130 cm³ - 5,000cm³ = 9,130 cm³

And the air is pumped at a rate of 180 cm³ per second, so the ball will be filled after t seconds:

180*t = 9,130

t = 9,130/180 = 50.7

Answer:

\(\frac{1}{200}\)

Step-by-step explanation:

Find the derivative of the function when x=3

\(y=\sqrt{2(x-1)}\)

\(\frac{dy}{dx}=\frac{1}{\sqrt{2(x-1)}}\)

\(\frac{dy}{dx}=\frac{1}{\sqrt{2(3-1)}}\)

\(\frac{dy}{dx}=\frac{1}{\sqrt{2(2)}}\)

\(\frac{dy}{dx}=\frac{1}{\sqrt{4}}\)

\(\frac{dy}{dx}=\frac{1}{2}\)

Since the change in the value of the function is \(dy\) and we know that the change in x is \(dx=0.01\), then we have:

\(\frac{dy}{dx}=\frac{1}{2}\)

\(dy=\frac{1}{2}dx\)

\(dy=\frac{1}{2}(0.01)\)

\(dy=\frac{1}{200}\)

In order to determine the associated risk measure in this equipment investment in terms of standard deviation, we need to use the following formula;

Risk = Standard Deviation * z score

Where z score is the number of standard deviations from the mean. A z score indicates how far away a data point is from the mean of a data set.

Standard deviation is used to measure the amount of variation or dispersion of a set of data values from the mean of a dataset. It can be used as a measure of risk associated with an investment in equipment. The higher the standard deviation, the higher the risk associated with the investment. Standard deviation can be calculated using various statistical software or spreadsheet programs.
