Question 9 Co/1 pt 9 100 99 0 Details A population grows according to an exponential growth model, with Po = 70 and P1 = 112 Complete the recursive formula: Pn = x Pn-1 Write an explicit formula for Pn Pn = Question Help: Video D Post to forum Submit Question . Question 10 0/1 pt ' 100 99 0 Details Suppose a population of honey bees in Ephraim, UT has an initial population of 6900 and 14 years later the population reaches 14000. Use an explicit exponential model to find the rate of growth and common ratio for the honey bee population. Express the rate of growth as a percentage. Round to the nearest tenth. % Express the common ratio as a decimal. Round to the nearest thousandth. 1 +r= Question 11 Co/1 pt ' 100 99 0 Details Starting in the year 2012, the number of speeding tickets issued each year in Middletown is predicted to grow according to an exponential growth model. During the year 2012, Middletown issued 240 speeding tickets (Po = 240). Every year thereafter, the number of speeding tickets issued is predicted to grow by 5%. If Pn denotes the predicted number of speeding tickets during the year 2012 + n, then Write the recursive formula for Pn Pn = x Pn-1 Write the explicit formula for Pn Pn = If this trend continues, how many speeding tickets are predicted to be issued in 2025? tickets Question Help: Video D Post to forum Submit Question Question 12 Co/1 pt ' 100 99 0 Details Inflation causes things to cost more, and for our money to buy less (hence your grandparents saying "In my day, you could buy a cup of coffee for a nickel"). Suppose inflation decreases the value of money by 5% each year. In other words, if you have $1 this year, next year it will only buy you $0.95 worth of stuff. How much will $100 buy you in 25 years
