Question 1025746
A baseball is hit so that its height in feet t seconds after it is hit can be represented by the following equation.
h(t) = -16t2 + 40t + 3

(a) What is the height of the ball when it is hit?
Find h(0)
================
(b) When does the ball reach a height of 15 feet?
h(t) = -16t2 + 40t + 3 = 15
Solve for t.
=======================
(c) When does the ball reach its maximum height?
Find the vertex of the parabola.
==========================
(d) What is the ball's maximum height?
