You are sky diving and are trying to land on a target with a radius of 15 m. You land 10 m west and 10 m north of the center of the target.

a. Write an inequality to describe the region inside the target area.
b. Do you land within the target area?
c. If another skydiver lands 4 m east and 14 m north of the center of the target, who is closer to the center.

I believe that the vertices would be (-15, 0) and (15,0), but I don't really know where to go from there.

  • trig -

    Let the center of the target be (0,0)
    You have a circle of radius 15.

    x^2 + y^2 < 225

    a square of side 10 has diagonal 14.14, just inside the target area

    4^2 + 14^2 = 16 + 196 = 212
    10^2 + 10^2 = 200

    so you are closer
