Homework Help: Math

Posted by Melia on Tuesday, October 30, 2012 at 9:20pm.

I know that year 2010, the population is 38.447 million and year 2011, the population is 38.935 million.

The formula given: A=36.1e^(0.0126*t)

Determine the population in 2010 and 2011 to nearest thousand people. Use these values to determine the increase in population to the nearest thousand people over this one year period.
What is this as an annual percentage growth rate with 2 digits after the decimal point?

I subtracted the populations and got 488,000 people.

Then I took that number and divided by 38.935 million to get the decimal answer and after that, I multiplied the decimal by 100 to get the annual percentage growth rate of 1.25%

Would that be the correct answer?
