(163 sin 120xt) 60 R If an appliance is plugged into a common household outlet, the wattage consumed is not constant Instead, it varies at a high frequency according to the model W=- Use the identity cos (20)=1-2 sin 20 to determine values of a, c, and w so that W= a cos (at) +c. Check your answer by graphing both expressions for W on the same coordinate axes. Find the equation for W, using the values of a, c, and . a=(Type a integer or decimal rounded to the nearest tenth as needed.) c=(Type an integer or decimal rounded to the nearest tenth as needed.) co= (Type an exact answer in terms of x.) where Vis the voltage and R is a constant that measures the resistance of the appliance.
