A person standing close to the edge on top of a 40- foot building throws a ball vertically upward. The quadratic function h(t) models the ball's height about the ground, h(t), in 16t + 72t + 40 - feet, t seconds after it was thrown. a) What is the maximum height of the ball? (Round your answer to the nearest hundreths.) feet b) How many seconds does it take until the ball hits the ground?
