Understand and apply exponentiation-Wind chill is the apparent temperature felt by exposed skin on a cold, windy day. Normally, there is a thin layer of warm air surrounding our bodies, and this warm air helps insulate us from the cold air around us. A strong wind reduces the amount of insulation by this air layer, so our skin loses heat at a faster rate than it would otherwise. Our skin feels colder, which makes us feel colder the temperature it "feels like" is the wind chill temperature. For example, if you re exposed to 30°F air moving at 20 mph, your skin loses heat at the same rate it would in calm 17.4°F air, so the windchill is 17.4°F. In 2001, the National Weather Service changed the formula used to calculate the wind chill index (the old formula produced temperatures that were too low). The new formula is: Wind Chill (in °F) = 35.74+ 0.6215 T- 35.75 (V0.16)+ 0.4275 T (V0.16) where T is the air temperature in °F and V is the wind velocity in mph. (In case
