Examine three consecutive even numbers. For example, numbers 2, 4 and 6. a) Multiply the middle number by itself and multiply the largest number by the smallest number. Calculate the difference of the products. Do the same with three new numbers. What can you say about the difference in the two surveys?

b) Show that the difference is always the same.
b) Feel free to use a general solution.

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.
