Describe fully the single transformation which takes shape A to shape B?

Analyzing the image and the given figure, this movement is:

This exercise is necessary to write the translation and rotation movement of the figure, this way this movement can be written in matrix form:

Where the X when positive represents movement to the right and when negative to the left. The Y represents when positive up and when negative down.

So the movement for figure A to be the same as for figure B is:

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.

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2
