At a garage sale, Petra priced her scooter for $19.25. She ended up selling it for $11.50. Find the percent of decrease in the price of the scooter. Round the percent to the nearest tenth if necessary.

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.
