Answer with Step-by-step explanation:

We are given that height of projectile after t seconds is given by

h(t)=96t-16t^2

a.h(t)=144 ft

144=96t-16t^2

16t^2-96t+144=0

t^2-6t+9=0

t^2-3t-3t+9=0

t(t-3)-3(t-3)=0

(t-3)(t-3)=0

t-3=0

t=3

After 3 s, the height of the project will be 144 feet in the air.

b.h(t)=0

96t-16t^2=0

16t(6-t)=0

16t=0\implies t=0

6-t=0\implies t=6

At t=0, the initial position of projectile

At t=6 s , the projectile will hit the ground.

(-1,6)(2,-6)
Svetlanka [38]

Answer:

E & F

Step-by-step explanation:

First find the slope of the line

m = (6 + 6)/(-1 - 2) = 12/-3 = -4

Now use the point-slope form

y - 6 = -4(x + 1)

y - 6 = -4x - 4

y = -4x + 2
