Answer:

a) 6.5 seconds
b) 13 seconds
c) 679 ft

Step-by-step explanation:

Given function:

h(t) = -16t^2 + 208t + 3

a) Maximum height is the vertex. The ball reaches the maximum after:

h = -208/2(-16) = 6.5 seconds

b) Time the ball was in the air:

-16t^2 + 208t + 3 = 0

Solving we get approximately t = 13 seconds

c) Maximum height is at vertex, we found t above:

h(6.5) = -16(6.5)^2 + 208*6.5 + 3 = 679 ft

Ifx=−8, evaluate the following expression:(x−2)(x+4)x(x+9)

tekilochka [14]

Answer:

= 40

Step-by-step explanation:

so if you mean x = -8

$(x - 2)(x + 4) \times (x + 9) \\$

$( - 8 - 2)( - 8 + 4) \times ( - 8 + 9)$

$( - 10)( - 4) \times 1$

$40 \times 1$

$40$
