Question

The annual number of passengers going through Hartsfield-Jackson Atlanta International Airport between 2000 and 2008 can be modeled as p(t) = -0.102t^3 + 1.39t^2 - 3.29t + 79.25 where output is measured in million passengers and t is the number of years since 2000. (a) Numerically estimate p'(3) to the nearest thousand passengers. 2296000 passengers per year Interpret the result. At the end of 2003, the number of passengers going through Hartsfield-Jackson International Airport was increasing by approximately [ ] per year. (b) Calculate the percentage rate of change of p at t = 3. (Round your answer to three decimal places.) [ ] % per year Interpret the result. (Round your answer to three decimal places.) At the end of 2003, the number of passengers going through Hartsfield-Jackson International Airport was increasing by approximately 2.596 % per year. Annual U.S. factory sales of consumer electronics goods to dealers from 1990 through 2001 can be modeled as s(t) = 0.0388t^3 - 0.495t^2 + 5.698t + 43.6 where output is measured in billion dollars and t is the number of years since 1990. (a) Numerically estimate the derivative of s when t = 12. (Round your answer to one decimal place.) 4891.04 billion dollars per year (b) Interpret the answer to part (a). At the beginning of year [ ], annual U.S. factory sales of consumer electronics goods to dealers were increasing by approximately $ [ ] billion per year.
