x= -15/4 => x= -3 3/4 or x= -3.75
Graphically I guess means graph it.
First graph goes to first problem. Second graph goes to second problem.
It hits the ground at h=0
0=-16t^2-16t+96
undistribute -16
0=-16(t^2+t-6)
factor
0=-16(t-2)(t+3)
set to zero
0=t-2
2=t
t+3=0
t=-3, nope, we can't have negative time
at t=2, or 2 seconds
Answer:
<h3>n=1,</h3>
=5
<h3>n =2,</h3>
=15
<h3>n=3</h3>
=33
