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.
Hope this helps!

That's all you need to do

This is about conversion of currencies.
<u><em>He spent £25 on the first day.</em></u>
- We are told he had spent £28 over 7 days.
Each day, he spends 50 pence more than the previous day. This means that;
1 pound = 100 pence
Thus, 50 pence = (50 × 1)/100 = £0.5
- If the money he spent on the first day is £x.
- On second day, he would have spent a total of; £(x + 0.5)
- On third day; x + 0.5 + 0.5= x + 1
- On fourth day; x + 1 + 0.5 = x + 1.5
- On fifth day; x + 1.5 + 0.5 = x + 2
- On sixth day; x + 2 + 0.5 = x + 2.5
- On seventh day; x + 2.5 + 0.5 = x + 3
x = 28 - 3
x = £25
