Graph Quadratic Functions Using Properties · Exercise 50
Solve. Round answers to the nearest tenth.
A stone is thrown vertically upward from a platform that is 20 feet height at a rate of 160 ft/sec. Use the quadratic function h(t) = −16t^2 + 160t + 20 to find how long it will take the stone to reach its maximum height, and then find the maximum height.
