The population of a town has approximately doubled every 17 years since 1950. If the equation P=Po2k, where Po is the population
of the town in 1950, is used to model the population, P, of the town t years after 1950, what is the value of k?
1 answer:
The population of a town has approximately doubled every 17 years since 1950.
the equation P=
where Po is the population of the town in 1950, is used to model the population, P, of the town t years after 1950.
When t=17 yrs
P=2
for 1 year
The equation becomes
P =
-------------(1)
Our original equation is
----------------------------------(2)
equating expression 1 and 2

Cancelling
from both sides we get

t/17=k
⇒k=t/17 is the solution.
