The present population, P, in thousands, of a town is related to the initial population of the town at time t = 0 by the formulaP = 185(2)(0.05t)where t is measured in years. The town was populated in 1880. What was the population (to the nearest 1,000) in the year 2000?

Best ResponseYou've already chosen the best response.0Is formula 185*2*0.05t

Best ResponseYou've already chosen the best response.0no im sorry the formula is 185(2)^(0.05t)

Best ResponseYou've already chosen the best response.0I think you mean: P(t) = \[185(2)^{(0.05t)}\] so if you subtract 20001880 to get t then substitute that into the equation.

Best ResponseYou've already chosen the best response.0t should be 120 120*.05 = 6 2^6 = 64 185*64 = 11840 people

Best ResponseYou've already chosen the best response.0or 12,000 people if you round

Best ResponseYou've already chosen the best response.0okay just to double check your answer, heres additional informatio. the population of the year 1880 was 185,000

Best ResponseYou've already chosen the best response.0then in that case set 1880= 185(2)^(0.05t) and solve for t. Add 120 to the t value and substitute that value back into the P(t)

Best ResponseYou've already chosen the best response.0from 1880 to 2000, 120 years have passed so this will be the t_value you use to evaluate the population in year 2000 \[P = 185*2^{.05*120}\] \[P = 185*2^{6}\] \[P = 11,840\] since this is in thousands add 3 zeroes

Best ResponseYou've already chosen the best response.0wouldnt you add 11,840 to the population 185,000 because thats how much the popultion increased over 120 years?

Best ResponseYou've already chosen the best response.0no because we left the 185 in the equation their initial population is already factored in the increase would be 11,840  185

Best ResponseYou've already chosen the best response.0in other words the equation gives population at any time t not just the increase

Best ResponseYou've already chosen the best response.0damn. well then maybe idid it wrong and maybe the population of 1880 isnt 185,000 .....ughh im confusing myself.

Best ResponseYou've already chosen the best response.0If what you posted above is correct then yes when t=0 in 1880 the population is 185,000
