The population in Zanzibar doubles every year. Currently there are 157634 people. Write a function of this growth.
To write a function that represents the population growth in Zanzibar, we can use the concept of exponential growth, where the population doubles every year. The general formula for exponential growth is:
P(t) = P(0) * (1 + r)^t
Where:
- P(t) represents the population at time t
- P(0) represents the initial population
- r represents the growth rate (in decimal form)
- t represents the time in years
In this case, the growth rate is 2 (as the population doubles every year), and the initial population is 157,634.
Therefore, the function that represents the population growth in Zanzibar would be:
P(t) = 157,634 * (2)^t
Where t represents the number of years from the start.
