$$t^3 - 5t^2$$
Karter
I said $$3t^2 - 10t$$
Karter
The derivative of a sum of terms is the sum of the terms' derivatives
You're right
so at x = 5 the slope is 25 right? unless I can't do simple math
here is the original problem
Have some confidence in yourself
ahhh $s'(t)=3t^2-10t$
Karter
The slope is exactly
3t^2 - 10t for t=5
Yes, that's the link between derivative and slope
Of tangent
