The wind-chill index (in degrees C) is modeled by the function W = 13.12 +0.6215T-11.37v0.16 +0.3965Tv0.16 where T is the air-temperature (°C) and v is the wind speed (km/h). When T = -19°C and v= 11 km/h, at what rate is windchill changing as air-temperature increases? (Round your answers to two decimal places.) °C of windchill per °C of air-temperature When T = -19°C and v= 11 km/h,, at what rate is windchill changing as wind-speed increases? (Round your answers to two decimal places.) °C of windchill per km/hr of wind-speed
