Answer 7

I can help don't worry. But you have to relax a little bit so I can explain it to you haha. Have you taken calculus at all? I can explain it using calculus or algebra, it's easier with calculus if you've taken it, but if you haven't that's fine too.

Answer 8

no this is for algebra 1

Answer 9

i am timed and need the answer please!

Answer 10

asap please

Answer 11

h(x) is your final height, s is your initial height, and v is your initial velocity.

It starts at 0 and ends at 0 height, right? It's in the middle where you have the highest height, so you use the quadratic equation to solve for t, and divide that time by half and plug in that time to find the h(x) at that time for your answer!

Answer 12

so which is the answer?

Answer 13

I didn't do the math, but I told you how to do it.
