Astore owner buys a total of 4,000 items for two different products. for shipping costs, it is $0.10 per item of product a and $0.04 per item of productb. if the total shipping cost is $352, which system of equations can be used to determine how much of product a and product b the store owner bought?

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.
