The point J(-2, 3) is rotated 90° clockwise around the origin. What are the coordinates of the resulting point, J′?

J' (3, 2)

Step-by-step explanation:

when a point is rotated 90 degrees clockwise, the point goes from (x, y) to (y, -x). You can imagine this rule or come up with it by doing a rotation on a graph, but really it's just a rule you should memorize.

So, apply (x, y) --> (y, -x) to this point:

(-2, 3) --> (3, 2)

J' (3, 2)

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.

the final price would be 29.6925

step-by-step explanation:

39.59 minus 25% equals 29.6925
