Triangle j'k'l' shown on the grid below is a dilation of triangle jkl using the origin as the center of dilation: two triangles are drawn on a grid. first triangle has vertices j 8 and 12, k 4 and 8, l 12 and 6. image triangle has vertices j which scale factor was used to create triangle j'k'l'? (1 point) 4 1 by 4 2 1 by 2

what are the statements

step-by-step explanation:

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.
