Answer Key
1. The formula to find the Heat Index, HI, when given the temperature, T, in Fahrenheit degrees and the Relative Humidity, R, is:
Expand by multiplying these three matrices together to get a polynomial of sixteen terms.
2. Now use this expansion to determine the Heat Index if the Temperature is 93 degrees Fahrenheit and the Relative Humidity is 21%.
3. Use this formula to determine the Heat Index if the Temperature is 100 degrees Fahrenheit and the Relative Humidity is 60%.
4. Use this formula to determine the Heat Index if the Temperature is 92 degrees Fahrenheit and the Relative Humidity is 46%.
