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 ᵒ F. The temperature adjusted for wind-chill tells you how cold it feels, as a result of the combination of wind and temperature.

Please help, thanks :)
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 ᵒ
F. The temperature adjusted for wind-chill tells you how cold it feels, as a result of the combination of wind and
temperature.
