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)

36 girls

step-by-step explanation:

the 48 boys is 4 parts of the ratio

divide 48 by 4 to obtain one part of the ratio

= 12 ← 1 part of the ratio

3 parts = 3 × 12 = 36 ← number of girls

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.

step-by-step explanation:

if you are looking for the unit rate then the answer would be 9 because unit rate is distance divided by time.
