18. [-/3 Points] DETAILS SCALCET8 14.3.090. MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER The wind-chill index is modeled by the function W = 13.12 + 0.62157 - 11.3710.16 + 0.3965710-16 where 7 is the temperature (C) and v is the wind speed (km/h). When 7 = -13.C and v = 12 km/h, by how much would you expect the apparent temperature W to drop if the actual temperature decreases by 10C? (Round your answers to two decimal places.) OC What if the wind speed increases by 1 km/h while the actual temperature stays constant at 7 = -13 C? OC Need Help? Read It
