An administrator of a popular website is told that a new faster server, which will replace the old server, can handle 45,000 hits (users accessing the site) per second. The website currently experiences a peak demand of about 110,000 hits per second. But, every month, the peak demand increases by 2500 hits per second. Use a prop
An economy's consumer price index is described by the function I(t) = -0.2t^3 + 3r^2 + 100 where t=0 corresponds to 1995. (0 <= t <= 10) At what rate was the CIP changing in 2000? In 2001? In 2002?
The demand for a certain commodity is given by D(x) = -50x + 800; that is, x units of the commodity will be demanded by consumers when the price is p = D(x) dollars per unit. Total consumer expenditure E(x) is the amount of money consumers pay to buy x units of the commodity. a) Express consumer expenditure as a function
Consumers' Surplus p = D(q) is the price (dollars per unit) at which q units of a particular commodity will be demanded by the market (that is, all q units will be sold at this price), and q0 is a specified level of production. Find the price p0 = D(q0) at which q0 units will be demanded and compute the corresponding consume
'Is the American Money System Metric?' and 'Why do you think the metric system was not adopted as Congress proposed?'
Two students in your class are having an argument about the American money system. One claims it is an example of the metric system and the other claims it is not.
