Answer: The ride descends 168 feet.

Step-by-step explanation:

24 Feet x 7 seconds = 168 feet

For every second it is 24 feet, so 24 x 7.

The total change in elevation will be descending 168 feet when the ride lasts for 7 seconds.

In mathematics, Multiplication operations perform Multiplying values on either side of the operator.

For example 4×2 = 8

Given that a ride at an amusement descends 24 feet each second.

We have to determine the total change in elevation when the ride lasts for 7 seconds.

The total change in elevation is equal to the multiplication of 24 feet each second and the ride lasts for 7 seconds.

According to the given question, the solution would be

Total change in elevation = 24 Feet × 7 seconds

Apply the Multiplication operation,

Total change in elevation = 168 feet

Thus, the total change in elevation will be descending 168 feet when the ride lasts for 7 seconds.

Step-by-step explanation:

The value of $\sin 2a$ is $\frac{35}{39}$. To find $\sin 2a$, we first need to determine the measure of angle $a$.

Since we are given that the area of the right triangle $abc$ is $4$ and the hypotenuse $\overline{ab}$ is $12$, we can use the formula for the area of a right triangle to find the lengths of the two legs.

The formula for the area of a right triangle is $\frac{1}{2} \times \text{base} \times \text{height}$. Given that the area is $4$, we have $\frac{1}{2} \times \text{base} \times \text{height} = 4$. Since it's a right triangle, the base and height are the two legs of the triangle. Let's call the base $b$ and the height $h$.

We can rewrite the equation as $\frac{1}{2} \times b \times h = 4$.

Since the hypotenuse is $12$, we can use the Pythagorean theorem to relate $b$, $h$, and $12$. The Pythagorean theorem states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.

So we have $b^2 + h^2 = 12^2 = 144$.

Now we have two equations:

$\frac{1}{2} \times b \times h = 4$

$b^2 + h^2 = 144$

From the first equation, we can express $h$ in terms of $b$ as $h = \frac{8}{b}$.

Substituting this expression into the second equation, we get $b^2 + \left(\frac{8}{b}\right)^2 = 144$.

Simplifying the equation, we have $b^4 - 144b^2 + 64 = 0$.

Solving this quadratic equation, we find two values for $b$: $b = 4$ or $b = 8$.

Considering the triangle, we discard the value $b = 8$ since it would make the hypotenuse longer than $12$, which is not possible.

So, we conclude that $b = 4$.

Now, we can find the value of $h$ using $h = \frac{8}{b} = \frac{8}{4} = 2$.

Therefore, the legs of the triangle are $4$ and $2$, and we can calculate the sine of angle $a$ as $\sin a = \frac{2}{12} = \frac{1}{6}$.

To find $\sin 2a$, we can use the double-angle formula for sine: $\sin 2a = 2 \sin a \cos a$.

Since we have the value of $\sin a$, we need to find the value of $\cos a$. Using the Pythagorean identity $\sin^2 a + \cos^2 a = 1$, we have $\cos a = \sqrt{1 - \sin^2 a} = \sqrt{1 - \left(\frac{1}{6}\right)^2} = \frac{\sqrt{35}}{6}$.

Finally, we can calculate $\sin 2a = 2 \sin a \cos a = 2 \cdot \frac{1}{6} \cdot \frac{\sqrt{35}}{6} = \frac{35}{39}$.

Therefore, $\sin 2

a = \frac{35}{39}$.

The composite function is f(t(p)) = 8e^(4p^2).

First, we need to substitute the expression for t in terms of p into the expression for f. We get:

f(t(p)) = 8e[t(p)]

Now, we can substitute the expression for t in terms of p:

f(t(p)) = 8e[4p^2]

Simplifying the expression, we get:

f(t(p)) = 8e^(4p^2)

Therefore, the composite function is f(t(p)) = 8e^(4p^2).

When working with functions, sometimes it is useful to combine them into a single composite function. To do this, we can substitute the expression for one function into the other and then simplify.

In this problem, we are given two functions, f(t) and t(p), and we are asked to write them as a single composite function using p as the independent variable.

The two widely used metrics of variation are the coefficient of variation (CV) and the standard deviation (SD).

Coefficient of variation (CV) is a measure of relative variation and is often used to compare variation between populations or groups with different means. It is calculated as the ratio of the standard deviation to the mean, multiplied by 100 to express the result as a percentage. It's a dimensionless value, which means it can be used to compare the variation of different variables that are measured in different units.

Standard deviation (SD) is a measure of the amount of variation or dispersion of a set of values. It is calculated as the square root of the variance, which is the average of the squared differences from the mean. Standard deviation is a measure of absolute variation and is typically used to describe the spread of data within a single population or group.

Both of these metrics are important in understanding the variation within a population, with the CV being useful in comparing different groups and SD being used to describe the spread of data within a single group.

The motion of the ant is a nonlinear graph;

It has its increasing segment at segment A, the constant segment at B and the decreasing segment at C.

THE TYPE OF GRAPH

The graph has 3 different straight lines, all of which point to different directions.

For a graph to be linear, such graph must have just 1 straight line. This means that the graph is nonlinear.

THE SEGMENTS OF THE GRAPH

The increasing segment of the graph is the segment that points in the upward direction.

In the attached graph, line segment A [i.e. from (0,0) to (2,16)] represents an upward movement of the ant because it points upward.

The decreasing segment of the graph is the segment that points in the downward direction.

In the attached graph, line segment C [i.e. from (4,16) to (6,0)] represents a downward movement of the ant because it points downward.

The constant segment of the graph is the segment that is represented by a horizontal line

In the attached graph, line segment B [i.e from (2,16) to (4,16)] represents the constant segment.

THE MOTION OF THE GRAPH

The ant travels at a constant speed through segment A. It then rests for 2 seconds in segment B and finally travels at a constant speed through segment C.

The average home size in the United States in 2004 was 7,000 square feet.

To solve this problem, we can use the concept of ratios. Let x be the average home size in 2004.

The concept of ratios involves comparing two or more quantities by expressing them as a fraction or a division of one quantity by another. It is used to determine how much larger or smaller one quantity is than another, and is often used in mathematics, science, finance, and other fields

We know that the average home size in 1970 was 1,400 square feet, and that the average size in 2004 was about 5 times greater. This can be expressed as:

x = 5(1,400)

Simplifying the right side of the equation, we get

a) To maximize its net savings, the company should use the new machine for 7 years.  b) The net savings during the first year of use of the machine are $405 (rounded off to the nearest dollar).  c) The net savings over the period determined in part a are $1,833.33 (rounded off to the nearest cent).

Step-by-step explanation: a) To determine for how many years should the company use the new machine to maximize its net savings, we need to find the value of x that maximizes the difference between the savings and the costs.To do this, we need to first calculate the net savings, N(x), which is given by:S'(x) - C'(x) = 175 - x² - (x² + 11x) = -2x² - 11x + 175To find the maximum value of N(x), we need to find the critical values, which are the values of x that make N'(x) = 0:N'(x) = -4x - 11 = 0 ⇒ x = -11/4The critical value x = -11/4 is not a valid solution because x represents the number of years of operation of the machine, which cannot be negative. (i.e., not use it at all).However, this answer does not make sense because the company would not introduce a new machine that it does not intend to use. Therefore, we need to examine the concavity of N(x) to see if there is a local maximum in the feasible interval.
