Question 1152923: in 1980, the population pf a city was 6.5 million. By 1992 the population has grown to 8.0 million . find the rate at which the population of the city was growing. Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! A=Aob^x
x=0, 1980
6500=6500 b^0
8000=6500(b^12)
8000/6500=1.23, but before rounding, take the 12th root
b=1.0174
the growth rate is 1.74%
