What are the x- and y- coordinates of point E, which partitions the directed line segment from A to B into a ratio of 1:2?

Step-by-step explanation:

The coordinates of A and B are missing in the question

Assuming point A is at (1,2) and B is at (1,9) then the coordinates of that partitions AB in the ratio m:n=1:2 is given by:

We substitute the values to get:

We simplify to get:

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.
