Answer: The money of in his piggy bank went down and he lost money is the effect
Step-by-step explanation:Answer is up there.
Answer: 7000
Note: 5 and up rounds up. 4 and below rounds down.
4 < 5 so that means we won't need to round up we round down.
7412 = 7000
If we were to round up then the answer would of been 7500.
I think it should be like this,
1) The function should be the last one, and it is in the form that shows zeros, the zeros show when the ball could hit the ground
2) Because she wants to know " after how many seconds the ball hits the ground", I think, that the ball's height above the ground should be
3) ball's height above the ground should be equal "0"
4)from the last equation we can see 2 zeros
t+3.2=0 and t-5=0, we get t1=-3.2 (that can not be accepted in our case, because time in this case cannot be negative), and t=5.
So at the end we should get this sentence(as I think)
The function h(t)=-5(t+3.2)(t-5) reveals that the ball's height above the ground will be 0 after 5 seconds.
