Task 1 Directions You have been studying sailing. As part of this you have been looking into storms and winds and its impact on sailing. You have found several radical equations that are used in weather.

Take each radical equation and write it with rational exponents.

In a hurricane, the mean sustained wind velocity v (in meters per second) can be modeled by 6.31013-p , where p is the air pressure (in millibars) at the center of the hurricane.
The mean sustained wind velocity has the equation:

Tsunamis, or large tidal waves are generated by underwater earthquakes in the Pacific Ocean. The speed of the tsunami in meters per second is 3.1d, where d is the depth of the ocean in meters.

  The median, because the distribution of wind speeds is skewed.

Step-by-step explanation:

A few higher speeds will raise the mean. For a skewed distribution, the median may be a more appropriate measure of center.

Additional comment

From an engineering point of view, one might have to consider speeds only within some range, as the wind turbines may be shut down for speeds too low or too high. Likely the power generated is not proportional to speed, so a weighted average (of the square of speed) would probably be more useful. Unfortunately, this question does not get into such subtleties.
