A map is a good example.
The Military
architectural purposes...
It is the coordinate or Cartesian plane.
A fjord is a real world example of a fjord! They exist in the real world.
A compound machine is two or more simple machines in one... Right so an example would be like...A BikeA pair of ScissorsA staplerAND SO ON...YOU GET IT:)
The Equator is a real world example, being the circumference of the Earth.
To plot a complex coordinate number, almost ignore "i". Find the real part, for example, 5, -8, pi, 0.98, the number that's not attached to the "i". Then find the imaginary part, the number attached to the i. The real part would be the x coordinate and the y would be the imaginary part. For example: (4-7i) would be plotted on x=4 and y=-7.
One example is the lengths of all the items on your desk, measured in centimetres (x-axis) and inches (y-axis).
Of what?
It could be the system of straight line equations that are plotted on the Cartesian plane.
where could you find a pentagon in the real world
