Hello I need a little help with my homework. I started trying to work it out but I am not sure if it is the correct solution. Please help!

Question:

Population growth. The exponential growth rate of the population of United Arab Emirates is 4.4% per year (one of the highest in the world). What is the doubling time?

Sources: Based on data from U.S. Census Bureau; International Data Base 2007

My Answer: I changed 4.4% to .044^2. My result was .001936 or round to 0.002%.

Is this correct? Should I be using the P(t) = P0e^kt? If so how should I go by doing so? Thanks for your help in advance!
