My Flower Basket delivers flowers within a 20 mile radius of their store. If this area is represented graphically, with My Flower Basket located at (5, 2), what is the equation that represents the delivery area?
A. (x - 2)2 + (y - 5)2 = 20
B. (x - 5)2 + (y - 2)2 = 20
C. (x + 5)2 + (y + 2)2 = 400
D. (x - 5)2 + (y - 2)2 = 400

	A.	(x - 2)2 + (y - 5)2 = 20
	B.	(x - 5)2 + (y - 2)2 = 20
	C.	(x + 5)2 + (y + 2)2 = 400
	D.	(x - 5)2 + (y - 2)2 = 400

mathmate · Answer

It is "within" a 20 mile radius, so it should be:
(x - 5)2 + (y - 2)2 < 20

thank you!

mathmate · Answer

Sorry, it's D.
I wasn't paying attention, it should have been r^2=400.
