Answer:
$15,360
Step-by-step explanation:
To find the retail price, multiply 12,800 by 1.2
12,800(1.2)
= 15,360
So, the retail price is $15,360
F⁻¹(x) stands for the invers of function f(x). The inverse of f(x) is equal to x. We need to solve for x.
solve for x
f(x) = 2x + 2
2x + 2 = f(x)
2x = f(x) - 2
x =
f⁻¹(x) =
Determine the value of f⁻¹(x) when x = 4
f⁻¹(x) =
f⁻¹(4) =
f⁻¹(4) =
f⁻¹(4) = 1
When x = 4, the value of f⁻¹(x) is equal to 1

Answer:
Step-by-step explanation:
p + n + d + q = 25
Put everything into quarters.
p and q are equally likely to be drawn
q + n + d + q = 25
There are 3 times as many nickels as quarters
n = 3q
q + 3q + d + q = 25
There is 25% more dimes than quarters.
d = 1.25 q
q + 3q + 1.25q + q = 25
6.25 q = 25
q = 25/6,25
=====================
q = 4
p = 4
d = 1.25 * 4 = 5
n = 12
2) The area is 1.1 m^2 because to find the area the formula is width*length. SO you would separate it. It would be 0.9 * 1 = 0.9 and 0.4 * 0.5 = 0.2. Then you add it together. So it would be 1.1 m^2. The perimeter is all the sides added together so 4.2 m, but it says mm so you have to convert it and you get 4200.
4) Area is 1.16 cm^2. Again you would seperate it. So, 1 * 1 = 1 and .2 * .8 = .16. Then you add it together and get 1.16 cm^2. The perimeter is all the sides added up. You get 4.2 cm.
