what is doubling time in exponential growth. The amount measured could be anything that is growing at a constant rate such as the population bacteria in a lab or money. In finance the doubling time is the period of time required for an investment or money in an interest-bearing account to double in size or value.
Time periods may be any measurement such as seconds hours days months or years. The doubling time of a population exhibiting exponential growth is the time required for a population to double. Exponential growth has surprising consequences.
How to compute the doubling time and half-life of exponential functions and to use doubling time and half-life to compute future population amounts.
The rule of 70 tells us it will also take 5 time intervals to double but in this case each time interval is 20 years. In finance the doubling time is the period of time required for an investment or money in an interest-bearing account to double in size or value. This island has a 14 growth rate over 20 years. Exponential growth is growth that increases by a constant proportion.
