For this case, the first thing we must do is define variables.
We have then:
x: altitude of the plane in feet
y: final temperature
The equation modeling the problem for this case is given by:
[tex] y = - \frac{1.1}{1000} x + 59.7 [/tex]
Thus, evaluating the function for x = 11,000 ft. Height we have:
[tex] y = - \frac{1.1}{1000} (11000) +59.7 [/tex]
[tex] y = 47.6 [/tex]
Answer:
the temperature at an altitude of 11,000 ft is 47.6 F
