1. Power companies typically bill customers based on the number of kilowatt-hours sed during a single billing period. A kilowatt is a measure of how much power (energy) a customer is using, while a kilowatt-hour is one kilowatt of power being used for one hour. For constant power use, the number of kilowatt-hours used is calculated by kilowatt-hours kilowatts time (in hours). Thus, if customers use 5 kilowatts for 30 minutes, they'll have used 5 kilowatts-hours = 2.5 kilowatt-hours. ● Suppose the power use of a customer over a 30-day period is given by the continuous function P = f(t), where P is kilowatts, t is time in hours, and t = 0 corresponds to the beginning of the 30 day period. A. Approximate, with a Riemann sum, the total number of kilowatt-hours used by the customer in the 30-day period, and explain why your Riemann sum is an approximation of the desired property. B. Derive an expression representing the total number of kilowatt-hours used by the customer in the 30-day period, and explain your reasoning. (This expression should not be an approximation.) C. Consider the following table of data for the function f(t).

6. Determine the power dissipated by the element of an electric fire of resistance 20 ohms when a current of 10A flows through. If the fire is on for 6 hours, determine the energy used and the cost if 1 unit of electricity costs P 0.65. 7. A business uses two 3kW fires for an average of 20 hours each per week and six 150W lights for 30 hours each per week. If the cost of electricity is P 0.64 per unit, determine the weekly cost of electricity to the business.
