Can someone pretty please help i just don't get the last part:( It says the following shows the estimated population and annual growth rates for four countries in the year of 2000. Find the expected population of each country in 2025 asuuming their growth rates stay the same. Can someone pleae help:(

I got the forumula No^e^rt

And i put in No=2000= 19,169,000

T= 25

R= 0.006

(0.006x25)= 0.15

19,169,000= (0.15)

And im stuck it just says rewrite it as natural log of one value minus natural log of the other value] How to do that , someone please help .

Step-by-step answer:

It is not clear what the question exactly wants, but here's the best I can do with possible interpretations.

Let P(t) = population t years after 2000, then

P(t) = (N0)e^(Rt)

where

N0=population of year 2000 = 19169000

R=rate of growth, in ratio = 0.006

e=base of natural logarithm = 2.7182818284...

Then

P(25) = 19169000*e^(0.006*25)

= 19169000*e^(0.15)

= 22271200.59885846

= 22271201

Not sure what it means "the other value", as we only have one.
