A projectile is shot vertically from the ground level. It’s height h, in feet, after t seconds is given by h = 88t - 16t ^2. How
kozerog [31]

Answer:

it will take 5.5 seconds to hit the ground

Step-by-step explanation:

A projectile is shot vertically from the ground level. It’s height h, in feet, after t seconds is given by h = 88t - 16t ^2

When the projectile hits the ground then the height becomes 0

h = 88t - 16t ^2

0 = 88t - 16t ^2

GCF is -8t

0 = 8t(11 - 2t)

now set each factor =0 and solve for t

8t=0, t=0

11-2t=0, t=\frac{11}{2}

So it will take 5.5 seconds to hit the ground
