Question:
On a particular day, the power used in a particular state
Last updated: 7/7/2022
On a particular day, the power used in a particular state (in thousands of megawatts) could be approximated by the function P(t)= -0.0068881³ +0.19181² -0.7085t+20.74, where t is the number of hours since midnight, for 0 ≤ t ≤ 24. Find any relative extrema for power usage, as well as when they occurred. Find the derivative of P(t). P'(t)=
