## anonymous 5 years ago A country's population in 1995 was 228 million. In 2001 it was 230 million. Estimate the population in 2010 using the exponential growth formula. Round your answer to the nearest million

$P _{t}=P _{0}e ^{kt}$ Find k $230 = 228*e ^{6k}$ $k = \frac{\ln 230/228}{6}$ Substitute this value in to find P15 2010-1995 = 15 $P _{15}=228*e ^{15*\ln (230/228)/6}$

can you solve it for me? i'm not sure how to

3. anonymous

i did solve it just calculate P15 using a calculator

4. anonymous

how do i do that?

5. anonymous

ok can you find ln(230/228) ?

6. anonymous

not sure

7. anonymous

press the ln button and then "(230/228)" did you understand any of the steps i did?

8. anonymous
