The Taino Indians threw a stone horizontally at a speed of \( 5.0 \mathrm{~m} / \mathrm{s} \) from the top of the Isabela mountain, which is 78.4 m high. a. How long does it take for the stone to reach the bottom of the mountain? b. How far from the base of the mountain does the stone hit the ground? c. What are the horizontal and vertical components of the rock's velocity just before it hits the ground?

16. Scott purchased men's sports coats for \( \$ 75 \) each and sold them for \( \$ 178 \) each. Find the markup on retail to the nearest whole percent A. \( 58 \% \) B. \( 56 \% \) C. \( 53 \% \) D. \( 55 \% \)

Remove the greatest common factor first. Then continue to factor, if possible. \[ 2 x^{2}+4 x y-12 y \] \( 2 x^{2}+4 x y-12 y=\square \) (Factor completely.)

Si \( \log a=3 y \log b=4 \), calcula: \( \begin{array}{llll}\text { a) } \log (a \cdot b) & \text { b) } \log \frac{a}{b} & \text { c) } \log a^{2} & \text { d) } \log _{a} b\end{array} \)

Use the given minimum and maximum data entries, and the number of classes, to find the class width, the lower class limits, and the upper class limits. minimum \( =9 \), maximum \( =79,6 \) classes
