The population P in 1997 for a state is given along with r, it's annual percentage of continuous growth. P=33 millions, r=1.7% (a) Write the formula f(x) =P erx, where r is in decimal notation, that model the population in millions x years after 1997 (b)Estimate the population in 2015

    The formula says Perx which is usually just an abbreviation for f(x)=Pe^(rx)

    or maybe it means: Write the formula f(x) =P erx, where r is in decimal notation, that model the population (in millions); x years after 1997

    33 e^(.017x) seems more reasonable then.... if I parse the question correctly

    x = 18...(2015) 33 * (e^(.017 * 18)) = 44.8134161 million

    no, I said 33 million was how you set the problem up; not the answer; you gave a 2 parter. :)

    part 1: set up an equation to use with this info: 33 e^(.017x) part 2) use it to find the population in 18 years

    33 million was part of the setup; in part 1.

    The population P in 1991 for a state is given along with r, it's annual percentage of continuous growth. P=34 millions, r=2.3% (a) Write the formula f(x) =P erx, where r is in decimal notation, that model the population in millions x years after 1991 (b)Estimate the population in 2016

    PART A :) 34 e^(.023x) PART B ;) 2016-1991 = 25 34 * (e^(.023 * 25)) = 60.4224379
