A factor tree branches down into 2 branches. The first number 1,225 branches down on the left to 5 and on the right to 245. 245 branches down to 5 on the left and 49 on the right. 49 branches down to 7 on the left and 7 on the right. A factor tree is shown for 1,225. What is the simplest form of StartRoot 1,225 EndRoot?

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.
