<u>Definition of ray in mathematics</u>
A part of a line with a start point but no end point (it goes to infinity)
However to draw a ray, you need the start point and at least one other point on the ray.
So the answer is minimum number of points needed for a ray is 2
When it hits the ground, then h=0
find the xintercept or in this case the tintercepts
c=76
v=135
h=-16t^2+135t+76
use quadratic formula
ax^2+bx+c=0
x=
a=-16
b=135
c=76
x=
x=
x=
aprox
x=-0.5297 or 8.967
exclude the negative root since you can't have negative time
means that it takes 8.97 seconds to hit the ground
