Problem 10
The formula used by the National Weather Service to calculate wind chill in degrees Fahrenheit is: $$ 35.74+0.6215 \times T-35.75 \times\left(V^{(0.16)}\right)+0.4275 \times T \times\left(V^{(0.16)}\right) $$ \(T\) represents the air temperature in degrees Fahrenheit, and \(V\) represents the wind velocity in miles per hour. Which of these is an accurate statement about the relationship between wind chill and temperature? I. The relative impact on wind chill of a particular increase in wind speed is more significant at lower wind speeds than at higher wind speeds. II. Wind chill has an impact on the relative temperature feeling only at temperatures greater than or equal to \(35.75\) degrees Fahrenheit. II. Wind chill and temperature are inversely related to one another. (A) I only (B) II only (C) \(\mid\) and \(\|\) only (D) \(\|\) and IIII only
