Answer:
Equation of line is given by:
Step-by-step explanation:
Given points:

Slope of line
where
and
is a point on the line



∴ 
Point-slope equation of line is given by:
where
is a point on the line and
is slope of line.
Using point
and slope
point-slope equation of line is given by:
Simplifying.
Using distribution.
Subtracting 2 to both sides.
Thus, equation of line is
I would divide each side of the equation by 4.
The answer is D
Solve for " t " by simplifying both sides of the inequality, then Isolating the variable.
Hoped this helped.
A
h(x)=6x^2+1
B
f(t)=-16t^2+48t
Before it hit the ground eqn would be
-16t^2+48t=0
16t^2=48t
t=3
3 seconds in the air before it hit the ground
0.008 as a percent is 0.8%.
