An airplane at an altitude of 35,000 feet begins descending at a rate of 2,000 feet per minute. How long will it take the airplane to reach the ground?

17 minutes and 30 seconds

Step-by-step explanation:

You would do 35,000 ÷ 2,000 = 17.5 therefore it's 17 minutes and 30 seconds until the airplane will reach the ground

1/800 is the right answer

b) k’(6, 4); l’(3, 3)

step-by-step explanation:

a 270° clockwise rotation maps every point (x, y) to (y, -x). (it negates the x-coordinate and then switches it and the y-coordinate.)

this means the endpoints of the side congruent to kl, k' and l', would be mapped as:

k'(-4, 6)→(6, 4)

l'(-3, 3)→(3, 3)
