The total cost of the triangular felt of the 24 square feet is 47.76 Dollars. Then the correct option is C.

Triangle is a polygon that has three sides and three angles. The sum of the angle of the triangle is 180 degrees.

Mr. Brooks is buying felt to cover a triangular putting green of his miniature golf course.

The base of the green is 4 feet wide, and the height is 12 feet.

The area of the triangle will be

[tex]\rm Area = \dfrac{1}{2}*base *height\\\\Area = \dfrac{1}{2}*4*12\\\\Area = 24[/tex]

The area of the triangle is 24 square feet.

The felt costs $1. 99 per square foot. Then the cost of 24 square feet will be

[tex]\rm Total\ cost = 1.99*24\\\\Total\ cost =\$ \ 47.76[/tex]

The total cost of the 24 square feet is 47.76 Dollars. Then the correct option is C.

Yes, solutions, roots, x-intercepts, and zeros are the same thing.

The general quadratic equation is given by:

a*x^2 + b*x + c = 0

So the solutions are the values of x such that the above thing is zero.

On another hand, a parabola or a quadratic function is given by:

a*x^2 + b*x + c = y

The roots, zeros, or x-intercepts (these represent the same thing) are given by:

a*x^2 + b*x + c = 0

So these are the values of x such that the function becomes equal to zero, so these are exactly the same thing as the solutions of a quadratic equation.

Concluding, yes, solutions, roots, x-intercepts, and zeros are the same thing.

Using simple interest, it is found that the monthly payment for this loan is of $325.485.

Simple interest is used when there is a single compounding per time period.

The amount of money after t years in is modeled by:

[tex]A(t) = A(0)(1 + rt)[/tex]

In which:

In this problem, the parameters are A(0) = 8100, r = 0.0822, t = 2.5, hence, the total amount is:

[tex]A(t) = A(0)(1 + rt)[/tex]

[tex]A(t) = 8100[1 + 0.0822(2.5)][/tex]

[tex]A(t) = 9764.55[/tex]

it will be paid over 2.5 x 12 = 30 months, hence the monthly payment is given by:

M = 9764.55/30 = $325.485.

Answer: (0,1)

Step-by-step explanation:

When a line crosses the y-axis, the x-coordinate must equal to 0.

Now we can plug in x = 0 into the equation given:

y - 4*0 = 1

y- 0 = 1

y = 1

Therefore, the point where the line crosses the y-axis is (0,1)

Answer:

No solution

Step-by-step explanation:

The slopes of both equations are identical (both being 2/3), therefore the only possible answers would be "infinitely many solutions" and "no solution". Because of the fact that the y-intercepts of the equations are different (-10 and 10) they two lines will never cross, meaning there is no solution.

Answer:

no solution

Step-by-step explanation:

[tex]\frac{2}{3} x - 10 = \frac{4}{6} x + 10[/tex]

Reduce the fraction:

[tex]\frac{2}{3} x - 10 = \frac{2}{3} x + 10[/tex]

Rearrange variables to the left side of the equation:

[tex]\frac{2}{3} x - \frac{2}{3} x = 10 + 10[/tex]

Apply the inverse property of addition

0 = 10 + 10

0 = 20

Based on the given conditions, the system of equations has no solution.

The function A(n) = 22(1.1)^n-1 is an illustration of a geometric series

The sum of the 23rd through 40th terms of the series is 17.49

The nth term of the geometric series is given as:

[tex]A(n) = 22(1.1)^{n-1[/tex]

The nth term of a series is represented as:

[tex]A(n) = ar^{n-1[/tex]

So, by comparison;

We have:

[tex]a = 22[/tex]

[tex]r = 1.1[/tex]

The sum of nth term of a geometric progression is:

[tex]S_n = \frac{a(r^n - 1)}{r - 1}[/tex]

Start by calculating the sum of the first 22 terms

[tex]S_{22} = \frac{22(1.1^{22} - 1)}{22 - 1}[/tex]

[tex]S_{22} = \frac{157.086}{21}[/tex]

[tex]S_{22} = 7.48[/tex]

Next, calculate the sum of the first 40 terms

[tex]S_{40} = \frac{22(1.1^{40} - 1)}{40 - 1}[/tex]

[tex]S_{40} = \frac{973.70}{39}[/tex]

[tex]S_{40} = 24.97[/tex]

Subtract S22 from S40

[tex]S_{40} - S_{22} = 24.97 - 7.48[/tex]

[tex]S_{40} - S_{22} = 17.49[/tex]

Hence, the sum of the 23rd through 40th terms of the series is 17.49
