b) The total payment to be made is $41,989.80.

c) The finance charge is $3,989.80.

The finance charge is the difference between the sum of the monthly payments and the loan amount.

The monthly payments, total payment, and finance charge can be computed using an online finance calculator as follows:

N (# of periods) = 60 months (5 years x 12)

I/Y (Interest per year) = 4%

PV (Present Value) = $38,000

FV (Future Value) = $0

Results:

PMT (Monthly Payments) = $699.83

Sum of all periodic payments (Total Payment) = $41,989.80

Total Interest (Finance Charge) = $3,989.80

The store that sells strawberries at a cheaper unit price is Fine Foods.

In Mathematics, a proportional relationship can be defined as a type of relationship that generates equivalent ratios and it can be modeled or represented by the following mathematical expression:

y = kx

Where:

In order to have a proportional relationship and equivalent ratios, the variables x and y must have the same constant of proportionality.

Next, we would determine the constant of proportionality (k) as follows:

Constant of proportionality (k) = y/x

Constant of proportionality (k) = 2/1 = 6/3 = 10/5 = 14/7

Constant of proportionality (k) = 2.

Therefore, an equation for the price of strawberries at Fine Foods is y = 2x and as such, it sells strawberries at a cheaper unit price.

The Atlantis water slide measures 70.69 feet in length when the slide's base is 37 feet from the pool and it is 60 feet tall.

The Pythagorean Theorem, often known as the Mathematicians, is the fundamental Euclidean geometry relation between the three sides of a right triangle. The area of a cube with the velocity vector side equals the sum of the areas of polygons with the other two sides, according to this rule. The Pythagorean Theorem says that the square that spans a right triangle's hypotenuse opposite the perfect distance equals a sum of the squares that span its sides. It is sometimes written as the basic algebra notation a2 + b2 = c2.

When graphing polynomials, we can determine the end behavior by the degree of the polynomial and the coefficient of the leading term.

The degree of a polynomial is the highest exponent of the variable found in the equation. The coefficient of the leading term is the number that is multiplied by the variable in the leading term. The end behavior of a polynomial can be determined by examining the sign of the coefficient and the degree of the polynomial.

For example, let's consider the polynomial equation y = x^3 - 2x^2 + 5x + 7. The degree of this polynomial is 3, and the coefficient of the leading term is 1. This means that the end behavior of this polynomial equation will be increasing, since the coefficient and degree are both positive. To confirm this, we can calculate the limit of the polynomial as x approaches positive and negative infinity. As x approaches positive infinity, the limit of y is positive infinity (∞), and as x approaches negative infinity, the limit of y is also positive infinity (∞). This confirms that the end behavior of this polynomial equation is increasing.

The proper method of finding a value table has been mentioned and explained below.

Value tables are a part of domain definition. The value table is maintained at the domain level and thus, is also called domain-level validation. Whenever you create a domain, you can enter the required values. Whenever you use this Domain, the system will make it so that you are forced to enter only these values. This is a sort of master check.

This means that if you want to enter values into this table you have to create a development request & transport the same. The system, then, proposes the value table as a check table. The check against the value table only takes place when a foreign key is defined

The midpoint method is a numerical integration technique used to approximate the definite integral of a function over a given interval. It is a Riemann sum method.

The line that connects these two places is split in half equally at the halfway. In addition, the halfway is reached if a line is drawn to divide the line that connects these two places. When we know the coordinates of two points, we can apply the midpoint formula to get the midpoint between them.

Here,

The midpoint method is used for a few reasons:

Simplicity: The midpoint method is relatively easy to understand and implement, compared to other numerical integration techniques.

Accuracy: The midpoint method is more accurate than some other Riemann sum methods like the left-hand rule or right-hand rule, which evaluate the function at the endpoints of each subinterval.

Efficiency: The midpoint method is more efficient than some other numerical integration techniques, especially for functions that are not smooth or have sharp changes.

Flexibility: The midpoint method can be used for both definite and indefinite integrals, and for functions that are not well-behaved.

Overall, the midpoint method is a simple, accurate, efficient and flexible numerical integration method that can be used to approximate the definite integral of a function over a given interval.

Step-by-step explanation: its because.......

the solution of equation  y=x+2 and  y=3x-2 are x= 2 and y=4

y = x+2 ------------ equation 1

y = 3x -2 ------------ equation 2

in the first equation y = x +2

in the second equation y = 3x -2

this mean equation 1 = equation 2

then we can equate the two together to get one of the variable

remember, we have to unknown variables which are x and y, so we need to isolate y to get x

x + 2 = 3x -2

let collect the like terms

x - 3x = -2 -2

let us factorize out x on the right hand side of the equation

x(1 - 3) = -4

x(-2) = -4

-2x = -4

divide both sides by -2

-2x/-2 = -4/-2

x = 2

The parent function of the quadratic family is f(x) = x2. A transformation of the graph of the parent function is represented by the function g(x) = a(x − h)2 + k, where a ≠ 0.

A quadratic function is one of the form f(x) = ax2 + bx + c, where a, b, and c are numbers with a not equal to zero.

A parabola is the shape of a quadratic function's graph. Although the "width" or "steepness" of a parabola can vary as well as its direction of opening, they all share the same fundamental "U" form. The three graphs in the image below are all parabolas.

A quadratic function's graph takes the form of a parabola. The parabola will open upward if the value of the "a" term is positive, and downward if the value is negative

A function can be raised by adding outside of it: f (x) + b raises f (x) by b units. The same principles apply for moving a function down, except instead of subtracting a positive integer, f (x) b represents f (x) moved down b units.

You can represent a vertical (up, down) shift of the graph of f(x)=x2 by adding or subtracting a constant, k.

f(x)=x2+k

By increasing or decreasing the output or the input, you can change the direction of the function's graph to the right, left, up, or down. A function's output can be increased to move the graph up. The graph is shifted downward when a function's output is subtracted from.

The output has a constant added to it, which causes the vertical shift. For a positive constant, move the graph upward; for a negative constant, move it below. A constant supplied to the input causes a horizontal shift. For a positive constant, move the graph to the left; for a negative one, move it to the right.

You can represent a horizontal (left, right) shift of the graph of f(x)=x2  by adding or subtracting a constant, h, to the variable x, before squaring.

f(x)=(x−h)2

If h>0, the graph shifts toward the right and if  h<0 , the graph shifts to the left.
