Apilot is flying a crj-900 from phoenix, arizona, to louisville, kentucky. the aircraft cannot take off or land if the temperature on the field is not within its operating
limitations. the aircraft cannot operate if the temperature is at or below -40° f. or at or above 118° f
part a: write an inequality to represent the temperatures the pilot can take off and land in (2 points)
part b: describe the graph of the inequality completely from part a use terms such as open/closed circles and shading directions. explain what the solutions to the
inequality represent. (4 points)
part c: in june 1990, the temperature in phoenix, arizona rose to 122°f. could the pilot have taken off on this day? why or why not? (4 points)

here's what i find.

step-by-step explanation:

part a. set up the inequality

let x = the temperature on the field.

you have two conditions

(1) x > -40

(2) x < 118

reverse equation (1)

(3) -40 < x

combine equations (3) and (2)

-40 < x < 118

part b. graph the inequality

i graphed the inequality on the number line below.

the red shaded area between -40 °f and 118 °f represents the temperatures in which the pilot can fly.

the open circles show that -40 °f and 118 °f are not included in the data set because the pilot cannot fly at those temperatures,

part c. x = 122 °f

122 °f is to the right of 118 °f. it is on the black portion of the number line and not in the acceptable red zone.

the pilot could not have taken off on this day, because hotter air is less dense than cooler air. the plane's wings cannot generate enough lift to get off the ground.

-22

times both sides by 2, times () by 8, add alile terms, move terms, add alike and caculate divide both sides by 3
