3. The length and width of a 6-inch by 8-inch photograph are reduced by the same amount to make a new photograph whose area is half that of
the original. By how many inches will the dimensions of the photograph
have to be reduced?

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.
