Answer:</h3>
5.51 seconds
<h3>
Step-by-step explanation:</h3>
y = 0 when the stone hits the ground. At that point, t can be found from ...
... 0 = -16t^2 +486
... 0 = t^2 -30.375 . . . . divide by -16
... 30.375 = t^2 . . . . . . add the opposite of the constant
Take the square root to get ...
... √30.375 = t ≈ 5.51 . . . . seconds
Answer:
x = 3
s = 11
z = 14
y = 2
Let me know if you need an explanation for this, I would be happy to help :)
The answer is there are no solution that fulfill this equation because if you put for example -14 the answer will be -8 but there is absolutely sign, so the answer is 8. Hope it help!
