The answer is $11,092.63.
This could be calculated using the proportion. If the value of the car decreases by 15% each year, that means that after each year the value of the car is 85% of the value from the first year.
After 1st year:
$25,000 : 100% = x1 : 85%
x1 = $25,000 · 85% ÷ 100%
x1 = $21,250
After 2nd year:
$21,250 : 100% = x2 : 85%
x2 = $21,250 · 85% ÷ 100%
x2 = $18,062.5
After 3rd year:
$18,062.5 : 100% = x3 : 85%
x3 = $18,062.5 · 85% ÷ 100%
x3 = $15,353.12
After 4th year:
$15,353.12 : 100% = x4 : 85%
x4 = $15,353.12 · 85% ÷ 100%
x4 = $13,050.15
After 5th year:
$13,050.15 : 100% = x5 : 85%
x5 = $13,050.15 · 85% ÷ 100%
x5 = $11,092.63
Therefore, the value of the car 5 years after it is purchased is $11,092.63.

What is the surface area of this composite solid?
The surface area of the given composite solid is calculated as: 200.24 square units.
How to Find the Surface Area of the Composite Solid?Surface area of the composite solid = surface area of rectangular prism + surface area of cylinder - 2(area of the base of the cylinder)
Surface area of rectangular prism = length * width * height = 10 * 3 * 5
= 150 square units.
Surface area of cylinder = 2πr(h + r)
height (h) = 4
Radius (r) = 2
Plug in the values:
Surface area of cylinder = 2 * 3.14 * 2(4 + 2) = 75.36 square units
Area of the base of the cylinder = πr² = 3.14 * 2²
= 12.56 square units
Thus, we have:
Surface area of the composite solid = 150 + 75.36 - 2(12.56) = 200.24 square units.

Express all real numbers greater than 2 in interval notation
The interval-notation for "all real-numbers" greater than 2 is (2, ∞).
The "Interval-Notation" is a way of expressing a set of real numbers using brackets to show which numbers are included in the set. In the case of all real numbers greater than 2, we can write this as:
(2, ∞)
The open-bracket "(" indicate that the number 2 is not included in the set, while the symbol "∞" represents all real numbers greater than 2.
This notation is used to express an open interval, meaning that the endpoints (in this case, 2 and infinity) are not included in the set.

Polynomial Functions
a) Yes, the function is in standard form.
Degree = 2
Exponent = 2
Constant term = -1
b) No, the function is not in standard form.
And it doesn't have the degree, exponent and constant term.
Firstly, let's consider the function f(x) = x(x-1). To determine if it is a polynomial function, we need to check if all of its terms have non-negative integer exponents. In this case, we see that f(x) can be written as x² - x, which has only two terms, and each term has a non-negative integer exponent. Therefore, f(x) is a polynomial function.
In this case, the degree of f(x) is 2 because the highest exponent of x is 2.
In this case, the leading term of f(x) is x², and its leading coefficient is 1.
Finally, the constant term is the term that does not have the variable in it. Here, the constant term of f(x) is -1.
Next, let's consider the function f(x) = 3 - 1/2 x. We can see that f(x) is not a polynomial function because it has a term with a negative exponent.
Polynomial functions must have non-negative integer exponents on all terms.
Therefore, the answer to the first question is 'no.'
Since f(x) is not a polynomial function, it does not have a degree, leading term, or constant term.

An equation that models the trigonometric graph is:
y = 4 sin 4x
How to interpret the trigonometric graph?The general form for an equation that models a wave is this:
±a (sin/cos) (2π(x - p)/T)
where:
a is the amplitude
p is the phase shift
T is the period.
The ±ve will turn into +ve if the graph tends to start from the positive direction, and then turns -ve if it the graph tends to start from the negative direction.
The (sin/cos) will definitely become sine if the graph starts at 0 before it is being shifted. Then, it becomes cosine if the graph begins at the amplitude.
In this problem, we see that the graph begins as positive, and then at the amplitude with no phase shift, we see that the ±ve becomes +ve, (sin/cos) becomes sin, and p becomes zero. Plugging in the given values in the problem, we see that a = 4 and T = π/2.
We see that this equation becomes:

Using the equations given, only equation 2 has a proportional relationship.
What is a proportional and non-proportional relationship?Proportional relationships are relationships between two variables where their ratios are equivalent. Another way to think about them is that, in a proportional relationship, one variable is always a constant value times the other.
The difference between proportional and non-proportional linear relationships is that, although both have constant rates of change the proportional relationship has constant output to input ratios, and the non-proportional relationship does not.
In this problem, to determine the proportional relationship, we can also check for both values of x and y.
1. y = -0.75x + 5
When x = 1
y = -0.75(1) + 5
y = 4.25
when x = 2
y = -0.75(2) + 5
y = 3.5
The relationship is not proportional since as one variable increase, the other decreases.
2. y = 4x - 1
When x = 1
y = 4(1) - 1
y = 4 - 1
y = 3
when x = 2
y = 4(2) - 1
y = 8 - 1
y = 7
This relationship is proportional since the variables increases or decreases with one another.
3. y = (3/4)x
When x = 1
y = (3/4)(1)
y = 3/4
when x = 2
y = (3/4)(2)
y = 2/3
