How do you calculate exponential population growth?
How do you calculate exponential population growth? From the given data, we can conclude the initial population value, x0, equals 10,000. Also, we have the growth rate of r = 5%. Therefore, the exponential growth formula we should use is: x(t) = 10,000 * (1 + 0.05)t = 10,000 * 1.05t . What is exponential […]
