#14) (AKS 3e) A construction worker needs to know how fast water will flow through a pipe. He can find this value using the formula =2gh, where v is the velocity of the water, g is the acceleration due to gravity, and h is the height of the water above the opening. a) On earth, the acceleration due to gravity is approximately 10 m/s2. Write a function, v(h), that represents the velocity of water on earth. b) What is the velocity, v, of the water if it is 23 meters above the opening? c) If the water's velocity is 7m/s. what is its height, h, above the opening? Unit 4 #15) (AKS 2a) Find the inverse of the function f(x) = 3-2. Once you find the inverse, prove the functions are inverses by using the inverse composition rule f(g(x)) = g(f(x)) = x.
