A town has a population of 20000 and grows at 4% every year. To the nearest

year, how long will it be until the population will reach 39400?

The population will reach 39,400 after 17 years.

Step-by-step explanation:

Given that, The population grows at a rate 4%. The population of the town is 20,000 at a certain time.

Exponential function:

y(t) = The population after t years

= Initial population.

r = Rate of grow

t = Time.

y(t)= 39400, = 20,000, r= 4%=0.04, t=?

Taking ln both sides

The population will reach 39,400 after 17 years.

the probability is 0
