Answer: 9 seconds
Step-by-step explanation:
When the object hit the ground,
Height h = 0
Therefore,
h(x)= -5(x+1)(x-9) = 0
0 = -5(x+1)(x-9)
Open the bracket
0 = (-5x - 5)( x - 9)
0 = -5x^2 + 45x - 5x + 45
0 = -5x^2 + 40x + 45
Divide all by -5
0 = x^2 - 8x - 9
Factorizing the equation gives
(x + 1)(x- 9)
x = -1 or 9
Since Time can't be negative
Therefore, the time seconds after launch the object will hit the ground is 9 seconds
Answer : Hershel buys 2 bags of fruit snacks.
Explanation :
Since we have given that
Number of bags of granola =3
Number of bags of cookies = 5
Total number of bags he buys from the bake sale =10
![\text{Remaining bags are of fruit snacks} =10-(5+3)=10-8=2](https://tex.z-dn.net/?f=%5Ctext%7BRemaining%20bags%20are%20of%20fruit%20snacks%7D%20%3D10-%285%2B3%29%3D10-8%3D2)
So, number of bags of fruit snacks = 2
Hence, Hershel buys 2 bags of fruit snacks .
