Answer:
2(x-√a)² + x - √a +1
Step-by-step explanation:
use x-√a as value for x
f(x-√a) = 2(x-√a)² + x - √a +1
C the horizontal line represents x and it goes to -1 you place your coordinates as (x,y)
So.... notice the picture below
we know when y = 140 and x = 240, r = 250
so let's use the pythagorean theorem

now... how much time does the controller have? well, say, plane "y" is going at dy/dt of 140mph, and is 70 miles away, 140 is 2*70, so it can cover those 70 miles in 1/2 hr, and when it does, it'll collide with the other,
so, the controller has that much, less than 1/2 hr
This is simple :)
If 9 chairs can fit in one box, and you have 3,456 chairs, just divide how many chairs you have by how many can fit in the box in order to find how many boxes you will need.
3,456/9 = 384
384 boxes will be needed
