Solve the problems below. Be sure to show your thinking. 11. Which of the following is a true statement? A. \( \sqrt{\frac{4}{16}} \) is \( \frac{2}{8} \), because \( \frac{4}{16} \div 2=\frac{2}{8} \). B. \( \sqrt{\frac{4}{16}} \) is \( \frac{2}{4} \), because \( \frac{2}{4} \times \frac{2}{4}=\frac{4}{16} \). C. \( \sqrt{\frac{4}{16}} \) is \( \frac{8}{16} \), because \( \frac{4}{16} \div 2=\frac{8}{16} \). D. \( \sqrt{\frac{4}{16}} \) is \( \frac{1}{4} \), because \( \frac{4}{16} \div 4=\frac{1}{4} \).

Enter the appropriate value to answer the question or 16. Graph the function \( f(x)=\sqrt{x+2}-5 \)

What function is the reflection of \( f(x)=|x+2| \) about the \( x \)-axis? \( g(x)=|x-2| \) Non of the other options \( g(x)=|-x+2| \) \( g(x)=-|x-2| \)

Find the domain and range of \( y=\log _{2}(8-4 x) \).

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

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.
