Use the Change of Base Formula and a calculator to evaluate the logarithm, correct to six decimal places. Use either natural or common logarithms. $$\log _{12} 2.5$$
Use the Laws of Logarithms to combine the $$\ln 5+2 \ln x+3 \ln \left(x^{2}+5\right)$$
Use the Laws of Logarithms to combine the $$\frac{1}{3} \log (2 x+1)+\frac{1}{2}\left[\log (x-4)-\log \left(x^{4}-x^{2}-1\right)\right]$$
Assume that a population of rabbits behaves according to the logistic growth model $$ n(t)=\frac{300}{0.05+\left(\frac{300}{n_{0}}-0.05\right) e^{-0.55 t}} $$ where \(n_{0}\) is the initial rabbit population. (a) If the initial population is 50 rabbits, what will the population be after 12 years? (b) Draw graphs of the function \(n(t)\) for \(n_{0}=50,500\) \(2000,8000,\) and \(12,000\) in the viewing rectangle \([0,15]\) by \([0,12,000]\) (c) From the graphs in part (b), observe that, regardless of the initial population, the rabbit population seems to approach a certain number as time goes on. What is that number? (This is the number of rabbits that the island can support.)
Use the Change of Base Formula to show that $$\log e=\frac{1}{\ln 10}$$
