In order for a line to be perpendicular to another, the product between the slopes needs to be equal to -1.
since the line x=8 is a vertical line and does not have a slope multiplying a variable, the perpendicular line needs to be a horizontal line.
the general equation for a horizontal line:
if it needs to pass through the point (-5,7), the y-coordinate will determine the equation
Answer:
5(-2a-8) < -9a + 4
Use distributive property on left side:
-10a -40 < -9a + 4
Add 40 to both sides
-10a < -9a + 44
Add 9a to both sides
-a < 44
Multiply both sides by -1 and reverse the inequality sign:
A > -44
Answer: a > -44
When the ball hits the ground, the height is 0.
0 = 100 - 16t²
0 = (10 - 4t)(10 + 4t)
0 = 10 - 4t or 0 = 10 + 4t
4t = 10 or -4t = 10
t = 
or t = 
Time cannot be negative (unless you have a time machine) so disregard
Answer: t = 
= 2.5 seconds
sin(48°) = x / 1200ft. Multiply each side by 1200ft.
1200ft × sin(48°) = x.
x = 891.77 ft.
