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

If you divide the first equation by 2 and the second by 3, you get

$4x+3=y\\4x-1=y$

These equations differ only in their y-intercept, so describe parallel lines. The appropriate choice is ...

... H The lines are parallel.
