The position of an object at time t is given by s(t) = -9 - 3t. find the instantaneous velocity at t = 8 by finding the derivative.

Hello! There are a few ways to find the derivative. One famous formula is below:

Note, t = x = 8

To find the derivative of s(t) = -9 - 3t let insert it into our formula:

Insert x = 8

So when t = 8 the instantaneous velocity = -3

24

step-by-step explanation:

i assuming that 2 sides are 6 the other 2 sides are 4 cm so 6 times 4 is 24 : )

a is the correct
