Answer 1

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
