Question

Can someone please help me with a me with a derivative question???

Answer 1

what is the question

Answer 2

The position of an object at time t is given by s(t) = -8 - 9t. Find the instantaneous velocity at t = 1 by finding the derivative.

Answer 3

ok... so can you find the 1st derivative...?

Answer 4

I think its s(t)=-9

Answer 5

close s'(t) = -9

which means the instantaneous velocity is a constant... so that means at t = 1 s'(1) = -9

Answer 6

so its just s'(1)= -9?

Answer 7

that's it... the constant -9 just means that for any t value, the velocity will be -9

hope it makes sense

Answer 8

Yes it does! Thanks @campbell_st
