omplete the following problem. Use proper notation and where relevant, answer in complete sentences. You can do this on a separate sheet of paper, take a clear picture of your work and upload your work into blackboard. City A has an initial population of 2.1 thousand. The population grows by 5% each year. City B has an initial population of 6.7 thousand. The population declines by 7% per year. a) Find a formula that gives the population A, in thousands, of city A after t years. A(t)= 2100(1.05)t b) Find a formula that gives the population B, in thousands, of city B after t years. B(t)= 6700(.93)t c) Make an appropriate graph that shows both populations over the first 20 years. Be sure to label your graph and indicate scale if you do this by hand. If you insert a picture of your calculator indicate the window and make sure point of intersection is visible. d) When will the populations of the two cities be the same? Round both values to two decimal places if necessary. What is the value of the population at that time? Round our answer to two decimal places if necessary. .
