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?
It may be stated as a doubling time, a birthrate per female, or a percentage of growth per year
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.
What is the doubling time of china in 2011?
In 2011, China's population doubling time was approximately 32 years. This means that based on the population growth rate at that time, it would take around 32 years for the population to double in size.
Given a growth rate of 3 percent per year how long will it take for a population of 100000 individuals to double?
It will take approximately 23 years for a population to double with a growth rate of 3 percent per year. This can be calculated using the rule of 70, where you divide 70 by the growth rate to find the doubling time. In this case, 70 divided by 3 equals 23.33, which can be rounded to 23 years.

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.
The overall growth of the U.S. population from 1990 to 2000 was 13 percent.What was the growth of the Hispanic population from 1990 to 2000?

What was the Philippine population growth from 2000 to 2007?
The Philippine population grew at an annual average growth rate of 2.04 percent from 2000 to 2007.
Took this entire time period for the population to double?
The time it takes for a population to double is known as the doubling time. It is calculated using the rule of 70, which states that you divide 70 by the growth rate to find the doubling time. For example, if a population is growing at a rate of 2% per year, it would take approximately 35 years for the population to double.
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.
What is the population growth rate in India?
2.1 percent per year
