The following questions refer to the table shown below, giving the temperature adjusted for wind-chill, C. in ° F, as a function f(w, T) of the wind speed, w, in mph, and the temperature, T, in F. The temperature adjusted for wind-chill tells you how cold it feels, as a result of the combination of wind and temperature.

Transcribed Image Text:The following questions refer to the table shown below, giving the temperature adjusted for wind-chill, C, in ° F, as a function f(w, T) of the wind speed, w, in mph, and the
temperature, T, in ° F. The temperature adjusted for wind-chill tells you how cold it feels, as a result of the combination of wind and temperature.
T=35T=30T = 25T-20T 15T = 10T = 5T=0
