Retail Sales November and December retail sales, excluding autos, for the years 2001–2010 can be modeled by the function
a. Graph the function for values of x representing 2001–2010.
b. During what years does the model estimate the sales to be $550 billion?
c. The recession in 2008 caused retail sales to drop. Does the model agree with the facts: that is, does it indicate that a maximum occurred in 2008?

- World Population A low-projection scenario of worldpopulation for the years 1995–2150 by the UnitedNations is given by the function y = -0.36x2 +38.52x + 5822.86, where x is the number of yearsafter 1990 and the world population is measured inmillions of people.a. Graph this function for x = 0 to x = 120.b.

- The table gives the yearly sales, S, of a retail store in years.arrow_forwardAmong all deaths from a particular disease, the percentage that is smoking related (21–39 cigarettes per day) is a function of the disease’s incidence ratio. The incidence ratio describes the number of times more likely smokers are than nonsmokers to die from the disease. The following table shows the incidence ratios for heart disease and lung cancer for two age groups. For example, the incidence ratio of 9 in the given table means that smokers between the ages of 65 and 74 are 9 times more likely than nonsmokers in the same age group to die from lung cancer. The rational function P(x) = 100(x - 1)/x, models the percentage of smoking-related deaths among all deaths from a disease, P(x), in terms of the disease’s incidence ratio, x. The graph of the rational function is shown. Use this function to solve, What is the horizontal asymptote of the graph? Describe what this means about the percentage of deaths caused by smoking with increasing incidence ratios.arrow_forwardAmong all deaths from a particular disease, the percentage that is smoking related (21–39 cigarettes per day) is a function of the disease’s incidence ratio.
