Given the rational function, answer the following questions.

Solve the following logarithmic equation. Be sure to reject any values that are not in the domain. $$\log_{3}(x+3) + \log_{3}(x+5) = 1$$

Use the properties of logarithms to condense the following logarithmic expression as much as possible. $$ \ln(7) +2 \ln(x) – 5\ln(w) – \ln(z) $$

Suppose that y varies jointly as x and z. Then y = 154.7 when x = 17 and z = 5.2.   What is the coefficient of variation (Round to the tenth place)? k = [cov] What is y when x = 3.2 and z = 15 (Round to the tenth place)? y = [y2]
