Question

The wind-chill index w is the perceived temperature when the actual temperature is T and the wind speed is v, so we can write W-nT, v). Wind speed (km/h) 203040 50 60 70 -10-18-20-2-2-23-23 -15-24-2627293030 20-3033343-36 37 -25 |-37 |-39 |-41 | -42 -43 -44 (a) Estimate the values of ft-15, 50) and (-15, 50). (Round your answers to two decimal places.) -15, 50) 从-15, 50): What are the practical interpretations of these values? by about When the actual temperature is 15°C and the wind speed is 50 km/h, the apparent temperature rises C for every degree that the actual temperature rises. when the actual temperature is-15°C and the wind speed is 50 km/h, the apparent temperature decreases by about C for every km/h that the wind speed increases. (b)In general, what can you say about the signs of ди//aT and away? For a fixed wind speed v, the values of the wind-chill index w Increase as temperature ǐ increases, so is positive s0 e dw For a fixed temperature T, the values of W decrease (or remain constant) as v | increases ▼ is , so (c) What appears to be the value of the following limit? lim w Need Help?
