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?

Use technology to find points and then graph the function \( y=\sqrt{x}+5 \) following the instructions below. Plot at least four points with integer coordinates that fit on the axes below. Click a point to delete it.

Convert the complex number, \( z=2 \) cis \( \left(\frac{3 \pi}{2}\right) \), from polar to rectangular form. Enter your answer as \( a+b i \).

6) Use the Laws of Logarithms to expand the expression. \( \log _{2}\left(\frac{x\left(x^{2}+1\right)}{\sqrt{x^{2}-1}}\right) \)

\( \frac{\sqrt{164+\sqrt{25}}}{\sqrt{140+\sqrt{16}}} \) 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. \( \log _{7} 8= \)
