Solve the problem.Suppose that a household appliance draws a current represented by the relation src="https://sciemce.com/media/4/ppg__jhjhj0506192304__f1q61g5.jpg" alt="" style="vertical-align: -4.0px;" /> where a, k, and d are constants.
where t is time measured in seconds. The power consumed by the appliance is 
where R is a constant. Take R to be 16 and graph the power in 
by 
and use an identity to write the expression for the power in the form
A. P = 392 cos(120?t) + 392
[0, 0.04, 0.01] by [-200, 2000, 200]
B. P = 392 cos(240?t) + 392
[0, 0.04, 0.01] by [-200, 2000, 200]
C. P = 784 cos(240?t) + 784
[0, 0.04, 0.01] by [-200, 2000, 200]
D. P = -392 cos(240?t) + 392
[0, 0.04, 0.01] by [-200, 2000, 200]
