Chapter 3: Problem 99
Determine whether the statement is true or false. Justify your answer. You can determine the graph of \(f(x)=\log _{6} x\) by graphing \(g(x)=6^{x}\) and reflecting it about the \(x\) -axis.

Solve the logarithmic equation algebraically. Approximate the result to three decimal places. $$\log _{2} x+\log _{2}(x+2)=\log _{2}(x+6)$$
Carbon 14 dating assumes that the carbon dioxide on Earth today has the same radioactive content as it did centuries ago. If this is true, the amount of \({ }^{14} \mathrm{C}\) absorbed by a tree that grew several centuries ago should be the same as the amount of \({ }^{14} \mathrm{C}\) absorbed by a tree growing today. A piece of ancient charcoal contains only \(15 \%\) as much radioactive carbon as a piece of modern charcoal. How long ago was the tree burned to make the ancient charcoal if the half-life of \({ }^{14} \mathrm{C}\) is 5715 years?
Solve the logarithmic equation algebraically. Approximate the result to three decimal places. $$\ln x-\ln (x+1)=2$$
(a) solve for \(P\) and (b) solve for \(t\). $$A=P e^{r t}$$
The number \(y\) of hits a new search-engine website receives each month can be modeled by \(y=4080 e^{k t},\) where \(t\) represents the number of months the website has been operating. In the website's third month, there were 10,000 hits. Find the value of \(k,\) and use this value to predict the number of hits the website will receive after 24 months.
