Question
In 1923, koalas were introduced on Kangaroo Island off the coast of Australia. In 1996, the population was 5000. By 2005, the population had grown to 27,000, prompting a debate on how to control their growth and avoid koalas dying of starvation1. Assuming exponential growth, find the (continuous) rate of growth of the koala population between 1996 and 2005. Round your answer to one decimal place. The continuous growth rate is % Find a formula for the population as a function of the number of years since 1996. The formula is P = Estimate the population in the year 2016 using your value of K. Round your answer to the nearest thousand koalas. The population in the year 2016 will be approximately thousand koalas.Explanation / Answer
suppose P = 5000e^rt 27000 = 5000*e^r(9) r =0.18737 so r= 18.74 % per year P(2016) =5000*e^r(20) = 212085.85 or 212085 or 212086...try any of these
