d(t) = -16t^2 + 16t + 9
(a) d(0) = 9
(c) the vertex is at t = -b/2a = 1/2.
(b) find d(1/2)
ritvik tosses a ball from where he stands on a balcony to his friend on the ground. the height, in feet, of the ball can be represented by the function d(t) = 16t to the power of 2 + 16t + 9 where t represents time in seconds. part a: from what height was the ball tossed? part b: what is the maximum height of the ball. part c: how long does it take the ball to reach its maximum height?
