I need help please this is my last homework question

(a) The power reaches its maximum at 14:00, or 02:00 pm

(b) The maximum power drawn by the household is 1.83 KW.

Step-by-step explanation:

Extreme points of real functions

Given a real function f(x), we can find the possible maximum or minimum points by computing the first derivative of f, f'(x), and equating it to zero.

The solutions of the resulting equation are the critical points of the function f.

The given function is

Where t is the number of hours after midnight and p(t) is the power in kilowatts.

Calculate the first derivative and equate to 0:

Solve for t:

(a) The power reaches its maximum at 14:00, or 02:00 pm

To find the maximum value, we use the value of t:

(b) The maximum power drawn by the household is 1.83 KW.

95.03 is the answer. hope this !

47.28 or 47.2857143

step-by-step explanation:

you just divide 331 by 7 and you get that answer. ( i think so tho)
