or in calculus, ds/dt

can you find the derivative of s ?

Answer 7

i got -38

Answer 8

I did not get that far. Did you find the derivative ? can you post it ?

Answer 9

s= -16t^2 - 10t + 100

you need to take the derivative term by term. Do you know how to do that ?

Answer 10

not really

Answer 11

it helps to use their equation:
s= -16t^2 + 10t + 100 you need to take the derivative term by term. Do you know how to do that ?

Answer 12

is it like factoring?

Answer 13

no, calculus is a lot different from algebra.
why are you doing this question ?

If you don't know calculus you can't do it.
