For the following exercises, use properties of logarithms to evaluate without using a calculator. $$ \log _{3}\left(\frac{1}{9}\right)-3 \log _{3}(3) $$
Use this scenario: A tumor is injected with 0.5 grams of Iodine-125, which has a decay rate of 1.15% per day. The half-life of Erbium-165 is 10.4 hours. What is the hourly decay rate? Express the decimal result to four significant digits and the percentage to two significant digits.
For the following exercises, state the domain, vertical asymptote, and end behavior of the function. $$f(x)=\log \left(x-\frac{3}{7}\right)$$
For the following exercises, use this scenario: The equation \(N(t)=\frac{500}{1+49 e^{-0.7 t}}\) models the number of people in a town who have heard a rumor after \(t\) days. How many people started the rumor?
Use this scenario: A tumor is injected with 0.5 grams of Iodine-125, which has a decay rate of 1.15% per day. To the nearest day, how long will it take for half of the Iodine-125 to decay?
