Answer:
Please,I don't get your question & kindly be specific
F(t) = (t^-1) - t
Taking derivative:
<span>f'(t) = d/dt(t^-1) - t) = d/dt(t^-1) - d/dt(t) </span>
<span>f'(t) = -1(t^-2) -1
= -t^-2 - 1 </span>
<span>f'(t) = v(t),
It can be also written as :
-1/t^2 - 1 </span>
<span>So v(3) = -1/(3^2) - 1 = -1/9 - 1 = -10/9</span>
Step-by-step explanation:
so what you need to do is answer the problems at the top to make then into a answer that looks like (x, y) ,(a,b) and find it on the graphs
7x-10=60
The answer would be x=10
I hope this helped!
