The wind-chill index is modeled by the function W = 13.12 + 0.62157 - 11.37v0.16 + 0.3965710.16 where T is the temperature (C) and v is the wind speed (km/h). When T = -6C and v = 48 km/h, by how much would you expect the apparent temperature W to drop if the actual temperature decreases by 1C? (Round your answers to two decimal places.) -1.36 X C What if the wind speed increases by 1 km/h while the actual temperature stays constant at 7 = -6.C? 0.62 X .C
