Consider the planes 2x + 1y + 5z = 1 and 2x + 5z = 0.

(a) find the unique point p on the y-axis which is on both planes. ( ? , ? , ? )

(b) find a unit vector u with positive first coordinate that is parallel to both planes.
? i + ? j + ? k

(c) use the vectors found in parts (a) and (b) to find a vector equation for the line of intersection of the two planes, r(t) =
? i + ? j + ? k

The equation of a circle is (x + 4)2 + (y + 6)2 = 16. determine the length of the radius. 10 4 16 8 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? (x - 2)2 + (y - 5)2 = 20 (x - 5)2 + (y - 2)2 = 20 (x + 5)2 + (y + 2)2 = 400 (x - 5)2 + (y - 2)2 = 400
