The brightness of the Sun as observed from the Moon can be used to design a solar panel array at a colony on the Moon. The Moon is 1.5 × 1011 m from the Sun. The array can convert energy from the brightness of the Sun into electricity at an efficiency factor of 39 percent. The power produced by the array is the efficiency factor times the product of the brightness (B) and area of the array (A): PRequired=(Efficiency)BA . What is the necessary area of the solar panel array, in square meters, to produce 39 kW? A = __m2.

In one of the videos I said that a typical American household uses energy at a rate of about 10,000 joules per second. A shorthand unit for this would be "10 kilowatts". Using energy at this rate costs about $1.50 per hour (this is not quite right, as it assumes that all the energy is electrical energy, which is relatively cheap, but let's go with this for an estimate). How much does this energy usage cost for a year?
The electrical power, P (in watts), transformed by an electrical appliance is given by P = f(i) = 9i2 , where i is the electrical current flowing through the appliance, in amps. Find f(10) and f'(10), and interpret them in the context of this problem.

Here's how gym membership works for a potential customer: If the customer decides to join the gym, she will pay J on day 0. Then, she can use the gym starting the next day for 5 days (1; 2; 3; 4; 5), paying an additional F on each day she visits. If she goes to the gym on any given day, it costs her (10+ F) that day, but beneÖts her 30 the next day. In other words, her "costs" are a sum of her psychic costs (10) and actual Onancial costs (F). Assume that, when indi§erent, the individual will go to the gym. (a) Suppose the potential customer is a standard exponential discounter with a discount factor of = 12. If gym membership was free (i.e. J = 0 and F = 0) would she join the gym? If so, how many days would she actually go? (b) Suppose the gym did not charge a joining fee. How high could it set the usage fee? What would its revenues from this customer be? (c) Suppose instead the gym decided not to charge a usage fee. How high could it set the joining fee?
