14. Which has a value greater than 600 but less than 6,000 ? \( \begin{array}{ll}\text { A. } 6.1 \times 10^{3} & \text { C. } 5.26 \times 10^{3} \\ \text { B. } 5.9 \times 10^{4} & \text { D. } 7.87 \times 10^{3}\end{array} \)

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

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

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

The half-life of radium is 1690 years. If 60 grams are present now, how much will be present in 430 years? \( \square \) grams (Do not round until the final answer. Then round to the nearest thousandth as needed.)

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.
