(1 pt) in cold weather, we feel colder when the wind blows. This is quantified by the wind chill index W1 which is supposed to predict how cold we will feel for a given air temperature Tl in degrees Fahrenheit, and wind speed V. in miles/hour. The National Weather Service uses the following formula W = 35.74 +0.6215T - 35.75V 0.16 +0.4275TV0.16) for T < 50 and V > 31 U Use your answer above to do the following question: When the air temperature is 6 degrees, estimate the change in the wind chill index if the wind speed increases by 2 miles/hour from 19 miles/hour.
