A. The functions are classified as follows:

B. The functions are defined as follows:

C. The value of each house after 25 years is given as follows:

There is a significant difference in the value of either house after 25 years, as exponential functions increase faster than linear functions, especially for larger input values.

A function is classified as exponential if when the input variable is changed by one, the output variable is multiplied by a constant.

Hence the house 1 has the value function as an exponential function, as:

312,519.92/303,417.40 = 303,417.40/294580 = 1.03

The function is defined as follows:

f(x) = 294580(1.03)^x.

And the value of the home after 25 years is given as follows:

f(25) = 294580(1.03)^25 = $6176,785.

A function is classified as linear if when the input variable is changed by one, the output variable is increased/decreased by a constant.

Hence the value of the house 2 is linear, as the rate of change each year is of $9,000.

The function is defined as follows:

f(x) = 295000 + 9000x.

The value after 25 years is given as follows:

f(25) = 295000 + 9000(25) = $520,000.

The tangent line is a special line that shares a single point of intersection with a given curve.

It is defined as the line that passes through the point of intersection and has the same slope as the curve at the same point. The concept of the tangent line comes from geometry, where it is used to measure a given angle in the form of a slope. In calculus, the tangent line is used to measure the rate of change of a function (or its derivatives) by considering the slope at any single point on the graph.

It is useful for calculating derivatives and integrals. In addition to this, the tangent line can also be used to understand the behaviour of the function in certain areas of the graph, or to determine its general form.

The equation for the line containing the vertical right edge of the arch is f(x) = -x + H, where H is the height of the arch, calculated as H = f(-b/2a).

To calculate the equation, we need to find the height of the arch. To do this, we need to solve for the vertex of the parabola. The vertex of the parabola is the maximum point of the arch, and can be found by setting the derivative of the equation equal to zero (f'(x) = 0).

The equation for the parabola is given by f(x) = ax² + bx + c, where a, b, and c are constants. Taking the derivative of this equation, we get f'(x) = 2ax + b = 0. Solving for x, we get x = -b/2a.

Plugging this value of x into the original equation, we get the height of the arch: H = f(-b/2a).

Now that we have the height, we can calculate the equation for the line containing the vertical right edge of the arch: f(x) = -x + H.

The equation for the line containing the vertical right edge of the arch is f(x) = -x + H, where H is the height of the arch, calculated as H = f(-b/2a).

The theories of motivation include theories X and Y. Managers use these theories, which are highly dissimilar from one another, to inspire their staff. While theory Y places an emphasis on rewards and recognition, theory X places more significance on supervision.

Let’s understand the application of Theory X and Theory Y:

While Theory X emphasizes the necessity of increased monitoring, outside rewards, and penalties, Theory Y emphasizes the significance of job pleasure as a motivator and encourages employees to approach jobs without direct supervision.

An organization that applies theory X will also have an authoritarian management style. There is hardly much management delegation of power. Companies that adhere to Theory Y, on the other hand, use a more decentralized approach, which means that employees share in authority. They are motivated as a result. Under theory Y, a few fundamental presumptions exist. One of them is that workers take ownership of their activities and work independently to further the objectives of the company. The employees are more engaged and attempt to resolve issues without the assistance of managers. This management approach is more prevalent than hypothesis X. Even a minor employee can take part in the decision-making process under this sort of management. Theory X relies on the notion of penalizing individuals in order to maintain employment, whereas theory Y emphasizes promotions, prizes, and recognition as key components. This maintains staff motivation to put in a lot of effort toward the organization's goals.

A piecewise function is defined as a function built from pieces of different functions over different intervals. For example, take piecewise function f(x) where f(x) = 2 when x ≤ 1, f(x) = x when x>1. We have a function, f(x) defined by

f(x) = 6 when x<6

f(x) = x when x ≥ 6

We have to determine the value of following integral, ₀∫¹⁰f(x)dx . As see, the function f(x) has two different in between the [0,10]. So, the required integral divided into two different parts, with different limits of it,

I = ₀∫¹⁰f(x)dx = ₀∫⁶ f(x)dx + ₆∫¹⁰ f(x)dx

=> I = ₀∫⁶ 6dx + ₆∫¹⁰ x dx

=> I = [ 6x]⁶₀+ [ x²/2]¹⁰₆

If a swimmer finished 1500-meter freestyle in 15.42 minutes, her speed is 3.6 miles per hour.

To convert the swimmer's speed to miles per hour, we need to first convert the distance she swam (1500 meters) to miles, and then we need to convert the time it took her to swim that distance (15.42 minutes) to hours.

We can use the following set of calculations to do this:

Convert the distance from meters to miles:

1500 meters × (3.281 ft / 1m) × (1 mile/ 5280 ft) = 0.93 miles

Convert the time from minutes to hours:

15.42 minutes × (1 hour / 60 minutes) = 0.257 hours

Divide the distance by the time to find the speed in miles per hour:

0.93 miles / 0.257 hours = 3.6 miles per hour

The total amount after 10 years would be $12968.71.

Compound interest is the interest paid on both principal and interest, compounded at regular intervals. At regular intervals, the interest so far accumulated is clubbed with the existing principal amount and then the interest is calculated for the new principal. The new principal is equal to the sum of the Initial principal, and the interest accumulated so far.

Compound Interest = Interest on Principal + Compounded Interest at Regular Intervals

The compound interest is calculated at regular intervals like annually(yearly), semi-annually, quarterly, monthly, etc; It is like, re-investing the interest income from an investment makes the money grow faster over time! It is exactly what the compound interest does to the money. Banks or any financial organization calculate the amount based on compound interest only.

Here,

P =  $5,000

r = 10% = 0.1

n = 1 (since the interest is compounded annually)

t = 10 years

The total amount after 10 years would be

[tex]A = P (1+ \frac{r}{n} )^{nt} \\A = 5000 (1 + \frac{0.1}{1}) ^{1*10}\\A = 5000 (1.1)^{10}\\A = 12968.71[/tex]
