Question: WIND CHILL FACTOR A formula used by meteorologists to calculate the wind chill temperature (the temperature that you feel in still air that is the same as the actual temperature when the presence of wind is taken into consideration) is
T = f(t, s) = 35.74 + 0.6215t - 35.75s0.16 + 0.4275ts0.16 (s ≥ 1)
Where t is the actual air temperature in degrees Fahrenheit and s is the wind speed in mph.
a. What is the wind chill temperature when the actual air temperature is 32°F and the wind speed is 20 mph?
b. If the temperature is 32°F, by how much approximately will the wind chill temperature change if the wind speed increases from 20 mph to 21 mph?
