Question

HELP PLEASE ANYONE!!!!!!!!!!!????

Answer 1

1.

(1 pt)
Airplane A takes off and ascends at a rate of 3000 ft/min. At the same time, Airplane B, which is flying at 30,000 ft, begins to descend at a rate of 2500 ft/min.

Let h represent the height off the ground in feet, and let t represent time in minutes.

Which system models this situation?

A.
h = 3000t
h = 2500 + 30,000t

B.
h = 30,000 + 3000t
h = 30,000 − 3000t

C.
h = 2500t
h = 30,000 − 3000t

D.
h = 3000t
h = 30,000 − 2500t

D

Answer 4

airplane A at the ground so h=0 and it climb with rate 3000 ft/min h=0+3000t
airplane B at height of 3000 ft so h=3000 and descent at rate 2500 ft/m so h= 30000-2500t

Answer 5

A hot tub holding 480 gal of water begins to empty at a rate of 5 gal/min. At the same time, an empty hot tub begins to fill at a rate of 15 gal/min. Let g represent the number of gallons of water and let t represent time in minutes. The system models this situation.

How long will it take for the hot tubs to hold equal amounts of water, and how much water will that be?

g = 480 – 5t
g = 15t

It will take minutes for both hot tubs to hold equal amounts of water. They will each hold gallons.
