3. Todd volunteers for the coast guard and gets to ride in the coast-guard helicopter. The pilot tells him that they will fly at a height of 148.5 metres above the ground. He adds that the flying height times 8,000 gives the square of the visible distance. How many kilometres will they be able to see?

\( \frac{\sqrt{164+\sqrt{25}}}{\sqrt{140+\sqrt{16}}} \) işleminin sonucu kaçtır? \( \begin{array}{llll}\text { (A) } \frac{14}{13} & \text { B) } \frac{13}{12} & \text { C) } \frac{7}{6} & \text { D) } \frac{17}{12}\end{array} \)

Use the change of base formula to evaluate \( \log _{7} 8 \) with your calculator. Round your answer to the nearest thousandth. \( \log _{7} 8= \)

3. Какое из данных равенств верно? \( \begin{array}{ll}\text { А) } 10^{-3}=-1000 & \text { В) }(-2)^{-3}=-\frac{1}{8} \\ \text { Б) }\left(-1 \frac{1}{3}\right)^{-2}=-\frac{9}{16} & \text { Г) } \frac{1}{7^{-2}}=-49\end{array} \)

5. Find the slope of the line between the two points of \( (5,8)(7,14) \) \( \begin{array}{ll}\text { a. } 3 & \text { c. } 2 \\ \text { b. } 4 & \text { d. } 5\end{array} \)

Determine the vertical asymptotes and holes (removable points of discontinuity) of the rational function shown below. \[ f(x)=\frac{(x-8)(x-1)}{(x-1)(x+9)} \] Use commas to separate results if there are more than one of each. If there is not a hole or asymptote, record DNE as your answer. Holes \( x= \) \( x= \)
