Velma sewed the quilt pictured below. it is 5 feet long and 9 feet wide. Her pattern consists of eight triangles that are congruent. How much material did she use to make the WHITE triangles? Show your work.

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.
