The answer is 8,916.56.
This is because 12% of the current price is 2904, times that by 5 years and then subtract the current price by the new number, and you get your answer.

If it decreases by 12 percent, you do 19,200x.12 which is 2,304. You subtract that from 19,200 which is 16,896. You multiply that by .12 which is 2,027.52 and subtract that from 16,896 which is 14,868.42. You do that three more times and there's your answer.

f(g(x)) is a composite function:

$f(g(x))=f(\sqrt{x+5})=2\sqrt{x+5}-1$

Plug in x = 4:

$f(g(4)) = 2\sqrt{4+5}-1=2\sqrt9-1=2\cdot3-1=\boxed{5}$

so the answer is C.

Perform the following operations and prove closure. Show your work. (x/x+3) + (x+2/x+5)

Westkost [7]

Answer:

$\frac{2(x^{2} + 5x + 3)}{(x+3)(x+5)}$

Step-by-step explanation:

We need to sum the following two expressions:

$\frac{x}{x+3} + \frac{x+2}{x+5}$

$\frac{x(x+5) + (x+2)(x+3)}{(x+3)(x+5)}$

expanding the polynomial in the numerator:

$\frac{2x^{2} + 10x + 6}{(x+3)(x+5)}$

$\frac{2(x^{2} + 5x + 3)}{(x+3)(x+5)}$

This is the most simplified form we can get:

$\frac{2(x^{2} + 5x + 3)}{(x+3)(x+5)}$

7. The diagram shows a regular pentagon inscribed inside the rectangle. Find the values of x, y, and z.

Wewaii [24]

regular pentagon sum of interior = (5 - 2) x 180 = 3 x 180 = 540
so
x = 540 / 5 = 108

180 - 108 = 72
y = 72/2 = 36

z = 180 - 90 - 36
z = 54

answer
x = 108, y = 36 and z = 54

A party rental company chairs and tables for rent. The total cost to rent 2 chairs and 12 tables is $105. The total cost to read

Luden [163]

Answer:

Step-by-step explanation:

2c+12t=105, and 5c+3t=33, subtracting 4 times the second from the first gives you

2c+12t-20c-12t=105-132

-18c=-27 dividing each side by -18

c=1.5, making 2c+12t=105 become

2(1.5)+12t=105

12t=102

t=8.5

So each chair costs $1.50 and each table costs $8.50
