Question

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.

Help Please!!!!

Answer 1

just differintiate the function..
\[V(t)=-9 \rightarrow V(1) =-9\]

Answer 2

i'm asking this because i'm really clueless when it comes to differentiating. Can you please explain how to?

Answer 3

when differentiating any function use the formula :
\[(ax ^{n} )\prime = a*n x ^{n-1} \] such that: a is constant (-9 in the case provided)
and n is the power of x
also the derivative of the constants is always 0
I think that's all u need to know at the moment

Answer 4

I am sorry not any function only polynomials and few others like \[\sqrt{x} , \frac{ 1 }{ x }\]
