Solve the following: #1: A city has been losing population. In the 1990 census it decreased by 15% from the 1980 census which showed that the city had 1.2 million people. If the percent of decline is expected to continue predict the population, create a table of values for the population in 1990, 2000, 2010 and 2020. What function would generate this table? Year 1990 2000 2010 2020 Population Pop = %3D

Solve the following: #1: A city has been losing population. In the 1990 census it decreased by 15% from the 1980 census which showed that the city had 1.2 million people. If the percent of decline is expected to continue predict the population, create a table of values for the population in 1990, 2000, 2010 and 2020. What function would generate this table? Year 1990 2000 2010 2020 Population Pop = #2: Another city showed the exact opposite, its population was increasing by 15%. If in 1980 it also had 1.2 million people create a table of values for the population in 1990,2000, 2010 and 2020. What function would generate this table? Year 1990 2000 2010 2020 Population Pop = #3: Compound interest earns interest on interest. 2000 is invested at 6.5% per year gives the function: P=(2000)(1+.065) How long will it take to double? # 4: On the day you were born your grandmother put $10,000 in a bank account for you that earned 5% interest per year. How much would you have on your 18th birthday? When you turned 65?
