Please explain the steps and answers

The windchill factor, W, is a measure of how cold it feels when taking into account both the temperature (degrees Fahrenheit}, t, and the wind velocity (mlles per hour), V. In the fall of 2001 the National Weather Service began using a revised Windchill formula based on new research on how wind and cold air affects people.T The formula the National Weather Service uses is the multivariable piecewise function: 3 mt, v) V C .
