use mathwsy
Step-by-step explanation:
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.
The answer is b -9 < x < 12
Answer:
its B
Step-by-step explanation:
Answer:
x= -
Step-by-step explanation:
First move the x on the right side the the left side. Now your equation is
2x+
=
Next move 1/2 to the right side. Now your equation is 4x=
. Next divide both sides by 4 to isolate "x." Now your equation is x= -
Hope this helped and have a great day.
