In 1997 the population of New York City was 7.277 million people and in 1998 the population of NYC grows exponentially. a Whit the 1-year growth factor? b. What it the 2-year growth factor? c The population of NYC in 2000 can be determined by the population of NYC in 1998 by the 1 -year growth factor. d Use your answer from above to help you predict the population of NYC in 2000. E. What is the 4-year factor? f Which of the following represents the population of NYC in 2001? 7.277 + 4(1.0273) 7.277 middot (7.476/7.277)^4 7.277 middot (7.476/7.277)^1/4 4 middot (7.277/1.02730 None of the above.
Solution
1997 ---- 7.277 million
1998 ---- 7.476 million
7.476/7.277 =1.027
Growth factor= 1.027
Two year growth factor : In two year population becomes 7.277(1.027)^2 = 7.675 million
2 year grwoth factor = 1.027^2 = 1.0547
Population in year 2000 can be found by multiplying population of 1998 with two year grwoth factor = 1.027^2 =1.0547
4 year growth factor : 1.027^4 = 1.112
