Julie swam, biked, and ran in a 22.2 mile triathlon. She completed the race in 2.15 hours. The function \( m=13.8 \mathrm{~h} \) represents the miles \( m \) Julie biked in \( h \) hours. Was her average speed biking less than or greater than her average speed for the entire race? Justify your answer. Round to the nearest tenth if necessary.

Which of the following is equivalent to \( \log \left(\frac{1}{x y}\right) \) ? (1 point) \( 1-\log x-\log y \) \( \log x-\log y \) \( -\log x-\log y \) \( -\log x+\log y \)

Use logarithms to solve the equation for \( t \). R \( e^{0.27}=8 \)

Simplify the logarithmic expression: \( \text{\log}_{2}(8) + \text{\log}_{2}(4) \)

30. List the first five terms of the sequence defined recursively by \( a_{n}=\frac{a_{n-1}}{2}+2 ; a_{1}=68 \)

Which of the following shows the equation \( 6^{2}=36 \) written in logarithmic form? (1 point) \( \log _{6} 36=2 \) \( \log _{2} 36=6 \) \( \log _{2} 6=36 \) \( \log _{36} 2=6 \)
