Show all the steps and work to solve each section.

1.As the altitudeincreases, both the air temperature and the dew point decrease. As long as the air temperature is greater than the dewpoint, clouds will not form. Typically, the air temperature T cools at 19F for each1-mile increase in altitude and the dew point D decreases by5.8F for each1-mile increase in altitude.Round answers to the nearest hundredth as needed.

1.a. Suppose the air temperature at ground level is 65F.

use a formula for a linear function T that gives the air temperature at x miles high.

1.b. Suppose the dew point at ground level is 65F

use a formula for a linear function D that gives the dew point at x miles high.

1.c. Use inequalities to determine the altitudes where clouds will not form.

1.d. Solve part (1.c) graphically. Take a picture of the window of your graphing calculator showing the intersection of the two inequalities.Note, you will need to adjust your window to graphically see the intersection.Insert your image here.
