Mica is solving for the zeros of a quadratic function by completing the square. Her work is shown. What error did Mica make? Mica should have set each x = 0 instead of f(x). Mica should have added 2 to 3 instead of 1. Mica should have multiplied both sides by 2 instead of dividing. Mica should have subtracted 1 from both sides instead of adding

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.
