Consider an ac circuit consisting of a power supply and a resistor. if the current in the circuit at time t is /, then the power delivered to the resistor is /, where r is the resistance. express the power in terms of cos 2wt

current in the circuit at time t is /, then the power delivered to the resistor is

step-by-step explanation:

In first Lucy's week, her profits were $50, in second week her profits increased by 10% and became $55 (10% from $50 is $5), in third week her profits increased by 10% from $55 and became $60.5 (10% from $55 is $5.5) and in fourth week her profits increased by 10% from $60.5 and became $66.55 (10% from $60.5 is $6.05).
In all over four weeks she will make $50+$55+$60.5+$66.55=$232.05
