What is the approximate doubling time in years for population with a 4 percent growth rate?

If the growth rate is 4 % per year, as may be intended to be implied, then the population after x years will be (1 + 0.04), 0.04 being the decimal equivalent of 4 %, raised to the xth power, or 1.04x = 2. This kind of equation can be solved with the aid of logarithms, since the logarithm of 1.04x = x(log 1.04), or x = (log 2)/(log 1.04) = about 18 years.

If a population or bank account is growing by the same percent age every year what type of growth does it exhibit?
Exponential Growth
What factors make doubling time decrease?
The rate of growth and, unless the relationship is exponential, the frequency of each growth cycle.
If a population consists of 10000 individuals at time t equals 0 years 'P0' and the annual growth rate is 3 percent 'GR' what will the population be after 1 15 and 100 years 'n'?
If a population consists of 10,000 individuals at time t=0 years (P0), and the annual growth rate (excess of births over deaths) is 3% (GR), what will the population be after 1, 15 and 100 years (n)? Calculate the "doubling time" for this growth rate. Given this growth rate, how long would it take for this population of 10,0000 individuals to reach 1.92 million? One equation that may be useful is:Pt = Po * (1 + {GR/100})nAdditionally, using the current world population from the census website, calculate world population in 2100 with growth rates of 2.3% and 0.5% Why is this important?THAT IS THE ENTIRE QUESTION! COULD SOME ONE PLEASE HELP ME!!!! THANK YOU
What are 3 ways that a growth rate may be stated or expressed?
doubling time, percentage of growth per year, and birthrate per female
What are the ways that a growth rate may be stated or expressed?

What is Germany's population doubling time?
Germany and other European countries' natural growth rate is actually negative (on average, women in Germany give birth to 1.5 children, which is below the number to yield zero population growth, approximately 2.1 children). Germany's natural growth rate of -0.1 can not be used to determine doubling time because the population is actually shrinking in size.

The Philippine population growth in 2008?
The Philippine population grew at an annual average growth rate of 2.04 percent from 2000 to 2007. From this rate, we can assume that the Philippine population will continue to grow by 2.04 percent in 2008 from its 88,545,270 population in 2007.

What is the formula for doubling the bacteria growth rate every 2 minutes in 1 hours?
I think the question means to say that the growth rate is (double every 2 minutes).doubling interval = 2 minutes1 hour = 60 minutes = (60 / 2) = 30 doubling intervalsStarting with 1 bacterium and reproducing asexually (do bacteria do this ? What do I know. I'm only an EE.) . . . . .If all survive, then the population after doubling 30 times = 230 = 1,073,741,824 bugs.
