Revenue In Exercises 49 and 50, two models, R1 and R2, are given for revenue (in billions of dollars) for a large corporation. Both models are estimates of revenues for 2020 through 2025, where t = 20 corresponds to 2020. Which model projects the greater revenue? How much more total revenue does that model project over the six-year period?

- Population The population P (in thousands) of Tallahassee, Florida, from 2000 through 2014 can be modeled byp=150.9ekt, where t represents the year, with t=0 corresponding to 2000. In 2005, the population of Tallahassee was about 163,075. (a) Find the value of k. Is the population increasing or decreasing? Explain. (b) Use the model to predict the populations of Tallahassee in 2020 and 2025. Are the results reasonable? Explain. (c) According to the model, during what year will the population reach 200,000?arrow_forwardVoting-Age Population The total voting-age population P (in millions) in the United States from 1990 through 2014 can be modeled by P=184.64+0.7524t21+0.0028t2,0t24 where t represents the year, with t=0 corresponding to 1990. (a) In which year did the total voting-age population reach 210 million? (b) Use the model to predict when the total voting-age population will reach 260 million. Is this prediction reasonable? Explain.arrow_forward
