An audio amplifier, represented by the AC source and the resistor R in figure, delivers alternating voltages at audio frequencies to the speaker. If the source puts out an alternating voltage of 15.0 V (rms), the resistance R is 8.20 ?, and the speaker is equivalent to a resistance of 10.4 ?, what is the time-averaged power delivered to the speaker?
