The wind-chill index is modeled by the functionW = 13.12 + 0.6215T − 11.37v0.16 + 0.3965Tv0.16where T is the temperature (°C) and v is the wind speed (in km/h). When T = −20°C and v = 25 km/h, by how much (in °C) would you expect the apparent temperature W to drop if the actual temperature decreases by 1°C? (Round your answers to two decimal places.) °C dropWhat if the wind speed increases by 1 km/h while the actual temperature stays constant at T = −20°C? °C drop
