College Algebra Math Question 3?
A person standing close to the edge on top of a 288-foot building throws a baseball vertically upward. The quadratic function s(t) = -16t^2 + 64t + 288 models the ball's height above the ground, s(t), in feet, t seconds after it was thrown. After how many seconds does the ball reach its maximum height? Round to the nearest tenth of a second if necessary.
