Graph Quadratic Functions Using Properties · Exercise 51

Solve. Round answers to the nearest tenth.

A ball is thrown vertically upward from the ground with an initial velocity of 109 ft/sec. Use the quadratic function h(t) = −16t^2 + 109t + 0 to find how long it will take for the ball to reach its maximum height, and then find the maximum height.
