When the ball reaches the ground is equal to one of the zeros, or x-intercepts. In order to find the zeros of a function, you need to factor the equation.
y=16x^2+64x
y=-16x(x-4)
The zeros are x=0 and x=4
Therefore the answer is D, after 4 seconds.

Answer:
Loss of $24,105
Step-by-step explanation:
Chen owns a record shop. Last year he sold $97,215 worth of merchandise. His costs were $73,110. we are asked to determine how much profit did he make?
Profit = current sale - previous year sales
current sale = $73,110
previous year sales =$97,215
as previous year sales is greater than current sales, there is a loss
Loss = previous year sales - current sale
Loss =$97,215
-$73,110
=$24,105
3x+5=2x-10
-2x -2x
X+5=-10
-5 -5
X=-15
3(-15)+y=5
-45+y=5
+45 +45
y=50
2(-15)-y=10
-30-y=10
+30 +30
-y=40
Divide by -1 on both sides
y=-40
If the width is 6.5 then double that to work out the two widths which would be 13. Take that from the perimeter so you're left with 21. Half 21 to work out one length which is 10.5. Length = 10.5
