A measure of what hot weather feels like to an average person is the Apparent Temperature Index. A model for this index is shown below, where A is the apparent temperature, t is the air temperature, and h is the relative humidity in decimal form. A = 0.885t - 22.4h+ 1.20th +0.544 (a) Find A/at and JA/Oh when t = 75°F and h = 0.90. (Round your answers to two decimal places.) OA/at= (No Response) aA/ah = (No Response) (b) which has a greater effect on A, air temperature or humidity? Explain. O The humidity has a greater effect on A because its coefficient -22.4 is larger than the coefficient 0.885 of the air temperature. The air temperature has a greater effect on A because its coefficient 0.885 is positive, unlike the coefficient -22.4 of the humidity.
