What do the

Do as the apples goes up in 4s

3 7 11  the goes 3 +4 = 7, 7+4 = 11

and  Sees goes up in 40's

30 70 110

and rate of change is

its 40/4 or 10/1 (that's the first one)

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.

where are the choices?
