Question:

At the beginning of Section 14.3 we discussed the heat index (perceived temperature) as a function of the actual temperature and the relative humidity and gave the following table of values from the National Weather Service

Actual temperature (F) 50 55 96 98 100 94 104 96 109 98 100 T H 90 92 Relative humidity (%) 60 65 70 100 103


Find a linear approximation for the heat index I = f(T, H) when I is near 96°F and H is near 70%. Use it to estimate the heat index when the temperature is 97°F and the relative humidity is 72%.
