Question
The wind-chill index W is the perceived temperature when the actual temperature is T and the wind speed v,so we can write W=f(T,v). The following table of values is an excerpt from Table 1 in section 14.1.Use the table to find a linear approximation to the wind -chill index function when T is near -15°C and v is near 50km/h .Then estimate the wind -chill index when the temperature is -17°C and the wind speed is 55km/h.
