The relationship between the air temperature T (in degrees Fahrenheit) and the altitude h (in feet above sea level) is approximately linear. [Hint: Use y=mx+b). When the temperature at sea level is 70 degrees, an increase of 5,200 feet in altitude lowers the air temperature about 20 degrees. a. Express T in terms of h. b. Approximate the air temperature at an altitude of 14,000 feet.
