Caitlyn is tossing a softball into the air with an underhand motion. The distance of the ball above her hand at any time is given by the formula

h(t)=64t-16t^2for 0≤t≤4

where h(t) is the height of the ball (in feet) and t is the time (in seconds).

At what times, t, is the ball in her hands?
The ball is in her hands at  seconds.    

At what time, t is the ball at it's maximum height?
The ball is at it's max height after how many seconds?

How high, h, is the ball at it's maximum height?
The ball's max height is how many feet?

Answer the following questions for the given problem: A ball is thrown up into the air. The ball’s height , h (in feet), from the ground is modeled by h(t) = -16t2 + 64t +5, where t is measured in seconds. Before answering these questions, think about the practical meaning of the vertex, y intercept and x intercepts, and how they apply to this problem. 1. What is the height of the ball at its highest point? 2. How many...
