Question

Problem:

Answer 1

A) replace x in the equation with 5 and 30 and solve for y:

y = -125(5) +40,000 = -625 + 40,000 = 39,375 feet after 5 minutes

y = -125(30) + 40,000 = -3750 + 40000 = 36,250 feet after 30 minutes.

B)

x = 0 y = 40,000

x = 5 y = 39,375

x = 8 y = 39,000

x = 10 y = 38,750

x = 30 y = 36,250

C) Initial value is when x is 0, which is 40,000 ft. this is the altitude of the plane before it started descending.

D)The rate of change is the number being multiplied by x, which is -125.

This means the plane is descending 125 feet per minute.

Answer 2

Answer:

replace x in the equation with 5 and 30 and solve for y:
