A ball is thrown into the air from a height of 4 feet at time t = 0. The function that models this situation is h(t)= -16t2 + 64t + 4, where t is measured in seconds and h is the height in feet. Use this information to answer the following questions. 1 When will the ball reach a height of 50 feet?

What is the maximum height of the ball?

After how many seconds will the ball hit the ground?

What domain makes sense for the function?

step-by-step explanation:

surface area of a pyramid is b + 1/2ph

b is the area of the base: 11 x 11 = 121

p is the perimeter of the base: 11 + 11 + 11 + 11 = 44

h is the height of the pyramid: 11

121 + 1/2(44)(11)

121 + 242
