Answer:
Max height = 21 feet
Yes - can reach the ledge
Step-by-step explanation:
For quadratics of the form
y = ax² + bx + c
The x coordinate of the vertex is at
x = -b/2a
therefor
t = (-32) / (2 * -16)
t = 1
h(1) = -16(1²) + 32(1) + 5
h(1) = 21
Max height = 21 feet
21 > 20
Yes - can reach the ledge
