The Average Speed of car for the round trip is 346.28 km/ hr.

Average Speed is calculated by dividing the total distance that something has travelled by the total amount of time it took it to travel that distance.

If a  car travels a distance d at rate r₁ and return the same distance at rate r₂, then,

Average Speed =  total distance ÷ total time

                          = 2d ÷ d/r₁ + d/r₂

                          = 2d ÷ r₂d + r₁d / r₁r₂

                          = 2r₁r₂ / r₁ +r₂

∴ x = 2× 3030×4040/ 3030 +4040

     = 2448240 ÷ 707

     = 346.28 km/hr

The area inside the loop of the limacon given by the polar equation r = 7 - 14sin(θ) is 294π square units.

To find the area inside the loop of the limacon given by the polar equation r = 7 - 14sin(θ), we need to evaluate the integral for half of the area and then double the result.

The curve of the limacon has a loop when 0 ≤ θ ≤ π, so we integrate from 0 to π. The area can be calculated as follows:

A = 2 ∫₀^π 1/2 r² dθ

Using the equation for r given, we can substitute and simplify:

A = 2 ∫₀^π 1/2 (7 - 14sin(θ))² dθ

A = 2 ∫₀^π 1/2 (49 - 196sin(θ) + 196sin²(θ)) dθ

A = ∫₀^π (98 - 392sin(θ) + 392sin²(θ)) dθ

Using the trigonometric identity 1 - cos(2θ) = 2sin²(θ), we can simplify further:

A = ∫₀^π (98 - 392sin(θ) + 196 - 196cos(2θ)) dθ

A = ∫₀^π (294 - 392sin(θ) - 196cos(2θ)) dθ

Integrating with respect to θ:

A = [294θ + 392cos(θ)sin(θ) + 98sin(θ)]₀^π

Evaluating at the limits of integration, we get:

A = [294π + 0 + 0] - [0 + 392cos(0)sin(0) + 98sin(0)]

A = 294π - 0 - 0 = 294π

Therefore, the area inside the loop of the limacon r = 7 - 14sin(θ) is 294π square units.

The derivative of y=cos3(sin(8x)) is dy/dx=-24cos2(sin(8x))sin(8x). This can be found using the chain rule, which states that the derivative of a composite function is the product of the derivative of the outer function and the derivative of the inner function. In this case, the outer function is cos3(x) and the inner function is sin(8x).

The chain rule states that the derivative of a composite function f(g(x)) is:

f'(g(x)) * g'(x)

In this case, the composite function is cos3(sin(8x)). The outer function is cos3(x) and the inner function is sin(8x). Therefore, the derivative of the composite function is:

(3cos2(x)) * (cos(sin(8x))) * (8)

Simplifying the expression, we get:

-24cos2(sin(8x))sin(8x)

This is the derivative of y=cos3(sin(8x)).

The function in variable w giving the cost C (in dollars) of constructing the box is C(w) = 30w² + 270/w. The result is obtained by using the formula of volume and area of the box.

We have a rectangular storage container without a lid.

The formula of volume of the box is

V = l × w × h

Where

So, the height is

10 = 2w × w × h

10 = 2w² × h

h = 10/2w²

h = 5/w²

To find the total cost, calculate the area of base and sides of the box!

See the picture in the attachment!

The base area is

A₁ = 2w × w = 2w² m²

The sides area is

A₂ = 2(2wh + wh)

A₂ = 2(3wh)

A₂ = 6wh

A₂ = 6w(5/w²)

A₂ = 30/w m²

The total cost is

C = $15(2w²) + $9(30/w)

C = $30w² + $270/w

The function of the total cost is

C(w) = 30w² + 270/w

Hence, the function of constructing the box is C(w) = 30w² + 270/w.

To determine which points are on the line of direct variation through (5, 12), we can use the equation of direct variation, which is given by y = kx, where k is the constant of variation.

Given the point (5, 12), we can substitute these values into the equation and solve for k:

12 = k * 5

k = 12 / 5

k = 2.4

The displacement and distance traveled depend on the given time interval.

To find the displacement, we need to integrate the velocity function from 0 to 5 or 0 to 5π, depending on the given time interval.

If the time interval is [0,5], we have:

Displacement = ∫[0,5] v(t) dt
Displacement = ∫[0,5] 6cos(t) dt
Displacement = [6sin(t)] from 0 to 5
Displacement = 6sin(5) - 6sin(0)
Displacement ≈ 2.785 meters

If the time interval is [0,5π], we have:

Displacement = ∫[0,5π] v(t) dt
Displacement = ∫[0,5π] 6cos(t) dt
Displacement = [6sin(t)] from 0 to 5π
Displacement = 0 - 6sin(0)
Displacement = 0 meters

To find the distance traveled, we need to integrate the absolute value of the velocity function over the given time interval.

If the time interval is [0,5], we have:

Distance = ∫[0,5] |v(t)| dt
Distance = ∫[0,5] |6cos(t)| dt
Distance = ∫[0,π/2] 6cos(t) dt + ∫[π/2,5] -6cos(t) dt
Distance = [6sin(t)] from 0 to π/2 + [-6sin(t)] from π/2 to 5
Distance = 6 - 6sin(5) ≈ 2.215 meters

If the time interval is [0,5π], we have:

Distance = ∫[0,5π] |v(t)| dt
Distance = ∫[0,5π] |6cos(t)| dt
Distance = ∫[0,π] 6cos(t) dt + ∫[π,2π] -6cos(t) dt + ∫[2π,3π] 6cos(t) dt + ∫[3π,4π] -6cos(t) dt + ∫[4π,5π] 6cos(t) dt
Distance = [6sin(t)] from 0 to π + [-6sin(t)] from π to 2π + [6sin(t)] from 2π to 3π + [-6sin(t)] from 3π to 4π + [6sin(t)] from 4π to 5π

the solutions to the equation -3x² + 5x + 4 = 0 are:

x = (-5 + √73) / (-6)

x = (-5 - √73) / (-6)

To solve the quadratic equation -3x² + 5x + 4 = 0, we can use the quadratic formula. The quadratic formula states that for an equation of the form ax² + bx + c = 0, the solutions for x are given by:

x = (-b ± √(b² - 4ac)) / (2a)

For our equation, a = -3, b = 5, and c = 4. Plugging these values into the quadratic formula, we get:

x = (-5 ± √(5² - 4(-3)(4))) / (2(-3))

The scale factor used is 8/3 or 2.67 (rounded to two decimal places).

What is the scale factor?

A scale factor is defined as the ratio between the scale of a given original object and a new object, which is its representation but of a different size (bigger or smaller).

The scale factor is the ratio of corresponding side lengths. Since the small triangle is the pre-image, its corresponding side length is the base of the large triangle. Therefore, the scale factor is:

scale factor = (corresponding side length of a large triangle) / (corresponding side length of a small triangle)

In this case, the corresponding side lengths are the bases of each triangle. So the scale factor is:

scale factor = (base of large triangle) / (base of small triangle)

The base of the small triangle is 3, and the base of the large triangle is 8. So the scale factor is:

scale factor = 8/3

Therefore, the scale factor used is 8/3 or 2.67 (rounded to two decimal places).

The statement that is true of the fourth step in the process of coding the responses to survey questions is that it follows the data entry phase of data preparation.

In the first paragraph, we can summarize the answer as follows: The fourth step in the process of coding survey responses involves assigning a coded value to each response, and it follows the data entry phase of data preparation.

The process of coding survey responses involves converting the qualitative information obtained from the survey into a coded format that can be analyzed and interpreted. After the data entry phase, where the survey responses are typically entered into a database or software system, the fourth step begins. During this step, each response is assigned a specific code or value that represents its meaning or category. This coding process allows for easier analysis and statistical manipulation of the data.

The reason why this step follows the data entry phase is that the data entry phase focuses on accurately capturing the survey responses without any interpretation or coding. Once the responses are entered, the fourth step takes place to assign the appropriate codes. By separating the data entry and coding phases, it ensures that the responses are captured accurately before any coding or interpretation is applied.

While the statement suggests that this step is automated and the easiest phase of the entire process, this may not always be the case. The complexity and ease of this step can vary depending on factors such as the nature of the survey questions, the coding system being used, and the clarity of the response options. Additionally, the statement that it is almost always necessary to avoid problems in the data entry phase is not accurate. The coding step is not directly related to avoiding problems in the data entry phase but rather focuses on transforming the data for subsequent analysis. Furthermore, the statement does not mention anything about omissions; therefore, it is not directly related to the process of coding the responses. Lastly, the statement correctly states that this step precedes the data validation phase, which typically involves checking the accuracy and consistency of the coded data.
