The wind-chill index is modeled by the function W = 13.12 + 0.62157 11.37v0.16 + 0.39657v0.16 where T is the temperature (C) and v is the wind speed (in km/h). When T = -16C 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 1C? (Round your answers to two decimal places.) C drop What if the wind speed increases by 1 km/h while the actual temperature stays constant at T = -16C? C drop
