20 units or 4.8
hope this helps!
Step-by-step explanation:
Answer: (13, -8)
Step-by-step explanation:
Subtract 5 from -3
Add 5 to 8
When it hits the ground the height would be 0.
Set h to 0 and solve for t ( time)
0 = -16t^2 + 112t + 144 divide both sides by -16:
T^2 -7t -9
Factor the polynomial :
( t- 8.1) (t+1.1
Solve for t setting each equation to 0:
T = 8.1 or t = -1.1
Time has to be positive, so the answer is
8.1 seconds
Depending on how everything gets rounded it could also be 8 seconds.
Answer:
Step-by-step explanation:
-(-)=+
so -8-(-3)=-8+3
=-5
Answer:
90°-33°=57°
57=2x+1
-1. -1
56=2x divide both sides by 2
28=x
x =28
