The concentration of pollutants , in grams per liter, in the river
Buriganga is approximated by P(x) = .04e−4x, where x is the number
of miles downstream from a tannery industry that the measurement is
taken. Find each of the following: • P(0.5), P(1) • The
concentration of pollutants 2 mi downstream • the number of miles
downstream where the concentration of pollutants is .002g per liter.

Michael is updating his estate plan for himself and his family. He would like to provide an income of $ 3000 every month starting 101 2 years from now and continuing for the next 20 years. He has started his account with an initial deposit of $ 10,000 and he knows his life insurance, maturing in five years, will have a cash value of $ 150,000. To make up the difference , Michael has decided to make monthly deposits in the account. How much should each deposit be if all interest is computed at 6 percent compounded monthly ?

a) Airbus makes 50 planes a year, which sell for $50 million each. If Airbus raises its price, Boeing will leave its prices unaltered, so Airbus loses market share. It faces an elastic demand curve. However, if Airbus cuts its price below $50 million, Boeing is forced to match the price cut, so quantity demanded increases only to the extent that additional plane orders are placed when planes are cheaper. Each company faces inelastic demand when it cuts the price. Draw the demand curve that Airbus thinks it faces.
