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.
Answer: Infinite solutions
Step-by-step explanation: 3x -7 = 3(x-3)+2
3x + -7 = (3)(x) + (3)(-3) + 2
3x + -7 = 3x + -9 + 2
3x - 7 = (3x) + (-7)
3x -7 - 3x = 3x - 7 - 3x
-7 + 7 = -7 + 7
0 = 0
Minus m-n = 36 so 36 is your answer.
