In order for an investment, which is increasing in value exponentially, to increase by a factor of 5 in 20 years, about what percent does it need to grow each year?

Explain how you know.

Here is the graph of the amount of a chemical remaining after it was first measured. The chemical decays exponentially.
What is the approximate half-life of the chemical? Explain how you know.

Explain why \log_{10}1=0.

How are the two equations 10^{2}=100 and \log_{10}(100)=2 related?
