WebIn 1950, the world's population was 2,555,982,611 . With a growth rate of approximately 1.68%, what was the population in 1955? Let's ignore the decimal part since it's not a full person. So, our guess is that the world's population in 1955 was 2,779,960,539. (The actual population was 2,780,296,616 so we were pretty close.) WebThe formula for population growth, shown below, is a straightforward application of the function. Given an initial population size P 0 and a growth rate constant k, the formula returns the population size after some time t has elapsed. P = P 0ekt. Note, as mentioned above, this formula does not explicitly have to use the exponential function.
