A plane is starting a descent to prepare for landing. The plane's initial altitude was 25,500 feet. The table below shows the altitude (y) of the plane after each minute (x) of the descent. Minutes (x) Altitude (y) 1 24,525 2 23,550 3 22,575 4 21,600 After descending for 4 minutes, the pilot was contacted by an air traffic controller. The controller asked how long it would take the plane to descend to an altitude of 15,750 feet at the current rate of descent. How many minutes should the pilot tell the air traffic controller that it's going to take? A. 5 minutes B. 7 minutes C. 4 minutes D. 6 minutes

step-by-step explanation:

believe it or not anna is correct good job anna give me a fist bump there u go gal

isocolese triangle

we know that the line connect a and b is the hyptonuse

so first find the hypotonuse length using the distance formula, call the length c

since it is an isocolese triangle, the lengths of the legs are the same

using pythagorean theorem,

in this case, a=b since isocolese triangle so we get

or

we can find c so we can find the distances

we know that if we draw 2 circles, each has center at a and b, and find where they intersect, we can the 2 possible locations for c

if a has center at (xa,ya) and b has center at (xb,yb), then we can solve where

and

intersect to find where they intersect

i'm not going to put an example because i have to go to class. i hope this explanation is enough
