A particle is moving through the xy-piane in such a way that its x coordinate is increasing at the rate of 1 m/s, and its y coordinate is decreasing at the rate of 3 mfs. Let D be the distance between the particle and the fixed point (0, 1). How fast is the distance D changing when the particle is at (2, 2)? Note that D is given by 02 =x2+(y1)2
