[tex]f = 30000 - (2000 \times m)[/tex] is an equation to represent the height of the airplane in feet above the ground f(x) in relationship to time in minutes x
Step-by-step explanation:
As given that the plane is at 30000 feet above the grounds. And starts descending at the rate of 2000 feet/ min
So, let us consider the below,
H= height in feet above ground
r = rate of descent
m = minutes
So, now frame the required equation format with the given data as follows,
[tex]H = 30000 - (2000 \times m)[/tex]
