Solve the problem.Suppose that a hair dryer operates on a voltage that can be represented by the relation 
and that it draws a current represented by the relation 
where t is time measured in seconds. The power consumed by the appliance is P = VI. Graph the power in 
by 
and use an identity to write the expression for the power in
the form 
where a, k, and d are constants.
A. P = -960 cos(240?t) + 960
[0, 0.04, 0.01] by [-200, 2000, 200]
B. P = 1920 cos(240?t) + 1920
[0, 0.04, 0.01] by [-200, 2000, 200]
C. P = 960 cos(120?t) + 960
[0, 0.04, 0.01] by [-200, 2000, 200]
D. P = 960 cos(240?t) + 960
[0, 0.04, 0.01] by [-200, 2000, 200]
