Answer:
<em>Answer: B'(-5,2)</em>
Step-by-step explanation:
<u>Rotations</u>
When rotating a point B(x,y) 90 degrees counterclockwise about the origin it maps to an image point B'(-y,x).
The image shows a figure formed by points ABCD. The coordinates of B are B(2,5).
This point will be rotated 90 degrees counterclockwise about the origin, thus the coordinates of the image point B' are B'(-5,2).

Please consider the diagram of cylinder.
We have been given that the mass of the cylinder is 50000 g. We are asked to find the density of the cylinder.
Let us find the volume of our given cylinder.
, where
r = Radius,
h = Height.
We know that radius is half the diameter, so radius of given cylinder would be mm.
Therefore, the density of the cylinder is approximately 2.7 gram per cubic mm.
If u work it out and both sides don't equal, then there is no solution.
Example :
2x + 4 = 2x + 6
2x - 2x = 6 - 4
0 = 2....this is incorrect...therefore, there is no solution
