Question

For a population growing at the rate you just described, consider the relationship between doubling time and log_e lambda as shown in this example: So, if a colony of bacteria is increasing by a rate of 0.02/minute, its doubling time would be approximately 34.5 minutes if it is growing exponentially. If a human population were to increase at a rate of 4% a year, its doubling time would be______years. Would you expect this population of bacteria in your lab to grow at the same rate for decades beyond 2209? Why or why not?

Explanation / Answer

solve for (1.04)^x = 2

x = ln2/ln(1.04) = 17.6 years
