Answer:
t=3
Step-by-step explanation:
subtract 3 on both sides (4t=12)
divide by 4 on both sides (t=3)
Answer:
The solution to the system of the equations will be:
Step-by-step explanation:
Given the system of the equations
solving the system of the equations
solving
Divide both sides by -2
Therefore, the solution to the system of the equations will be:
Answer:
- h = 0 when the ball hits the ground
- about 3.464 seconds
Step-by-step explanation:
The formula gives h = 192 when t=0, so we assume that h represents the height above the ground. The ball will have a height of 0 when it hits the ground.
__
Using that in the equation, we can solve for t.
0 = 192 -16t^2
0 = 12 -t^2 . . . . . . divide by 16
t^2 = 12 . . . . . . . . add t^2
t = √12 = 2√3 ≈ 3.464 . . . . take the square root
It will take 2√3 seconds, about 3.464 seconds, for the ball to hit the ground.
