Question

The population of the United States was about 280 million in 2000 and about 310 million in 2010.what was the annual rate of change in population from 2000 to 2010/5408984/421f1121?utm_source=registration

Answer 1

A=P.e^(rt), where P = previous population, A = actual population
t=number of years and = growth rate

310 = 280.e^10r)
310/280 = e^(10r)

1,1071428= e^(10r)

ln(1.1071428) = 10r.ln.e

0.101782  = 10.r 

r= 0.101782/10 = 0.01017 or 1.017%
