The wind-chill index is modeled by the functionW = 13.12 + 0.62157- 11.37v0.16 + 0.39657v0.16where T is the temperature (°C) and v is the wind speed (in km/h). When T = -14°C and v= 35 km/h, by how much (in °C) would you expect the apparent temperature W to drop if theactual 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 = -14°C?°C drop

On wet roads, under certain conditions the front tires of a car will hydroplane, or run along the surface of the water. The critical speed V at which hydroplaning occurs is a function of p, the tire inflation pressure. Suppose the following table shows hypothetical data for p, in pounds per square inch, and V, in miles per hour. Find a formula that models V as a power function of p. Round parameters to the nearest hundredth. Tire inflation pressure p Critical speed for hydroplaning V 25 52.5 30 57.4 35 62.0 40 66.2 a) V = 35.89 x p^0.02 b) V = -41.49 x p^67.11 c) V = 29.82 x p^0.91 d) V = 10.70 x p^0.49

Tide height as a function of time resembles a sinusoidal function during the time between low and high tide. At one such location on another planet with water, the tide has a high of 12.7 feet at 2 am and then the next low is -0.8 feet at 11 am (9 hours later). Find a formula for a sinusoidal function H(t) that gives the height tt hours after midnight.
