I think that is the answer
Answer:
Ok, suppose you want to create a battery that fits exactly in the hole that is already created for an electric device, like a cellphone for example.
If the battery is slightly bigger, it will not enter the socket, and the battery will be a loss in time and resources.
If the battery is slightly smaller, it will move when it is in the socket, so the cell phone will shut down randomly when you move it, then this battery is also a loss in time and resources.
So you need to measure exactly the socket in order to make a battery that fits exactly inside of it with very good precision.
This example can be extended for any electronic piece that you need to fit in a given space (for example in microtechnology, the precision of the measures is must be extreme because working with those things is really expensive and you can not mess up with the dimensions of the pieces)
It cannot be simplified:(
it is already in simplest form
Suppose that X is a vertical segment that lies on the y-axis with its beginning at origin and ending at the point (0,4). Then the length of this segment is 4 units.
If you vertically compress this segment by factor of 1/4 with the centre of compression at the origin, you recieve a segment that also lies on the y-axis with its beginning at origin and ending at the point (0,1) (the length of this image segment is 1 unit).
So, the question is: if a segment that lies on the y-axis with its beginning at origin and ending at the point (0,4) is vertically compressed <span>by factor of 1/4 with the centre of compression at the origin, what is the image of this transformation?

150 because if you take 180 and subtract 30 u get 150
