3. use the diagram to the right to name the following.
a) three coplanar points.
b) a plane containing point x.
c) the intersection of plane r and plane zvy.
d) how many planes appear in the figure?
e) how many planes contain point w? _

Sketch the vector field vector f( vector r ) = 8vector r in the xy-plane. select all that apply. the length of each vector is 8. the lengths of the vectors decrease as you move away from the origin. all the vectors point away from the origin. all the vectors point in the same direction. all the vectors point towards the origin. the lengths of the vectors increase as you move away from the origin.
