Jack draws a rainbow which is a parabola shape that has the equation h=-0.1(x-1)2+6 where x and y are measured in centimeters. How far away are the end points of the rainbow from one another

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.
