Acommunity pool that is shaped like a regular pentagon needs a new cover for the winter months. the radius of the pool is 20 ft. the pool is 24 ft on each side.

to the nearest square foot, the area of the pool that needs to be covered
is sq ?

F(x)= 1/x-4, g(x)=4x+1/x a. use composition to prove whether or not the functions are inverses of each other. b. express the domain of the compositions using interval notation.

What is the y intercept of f(x)=(1/2)^x?

The length of a rectangle is x times the square root of 100. the width is one-half y more than three-halves x. given that the area of the rectangle is 125 cm2, which equation could represent the rectangle in terms of x and y? a) 5xy − 15x = 125 b) 5xy + 15x = 125 c) 15x2 − 5xy = 125 d) 15x2 + 5xy = 125
