On a particular day, the power used in a particular state (in thousands of megawatts) could be approximated by the function
P(t) = - 0.006566t° + 0.1975 – 1.071t+ 18.63
where t is the number of hours since midnight, for 0sts24. Find any relative extrema for power usage, as well as when they occurred.
Find the derivative of P(t).
P'(t) = -0.019698t2 + 0.395t – 1.071
Find any relative extrema for power usage, as well as when they occurred. Select the correct choice below and, if necessary, fill in any answer boxes within your choice.
O A. There are no relative maxima. The relative minimum/minima is/are
(Use a comma to separate answers as needed. Type integers or decimals rounded to the nearest hundredth as needed.)
at the t-value(s) t=
O B. The relative maximum/maxima is/are
at the t-value(s) t=
and the relative minimum/minima is/are
at the t-value(s) t=
(Use a comma to separate answers as needed. Type integers or decimals rounded to the nearest hundredth as needed.)
O C. There are no relative minima. The relative maximum/maxima is/are
at the t-value(s) t =
(Use a comma to separate answers as needed. Type integers or decimals rounded to the nearest hundredth as needed.)
O D. There are no relative extrema.
