3.5 is rounded to the nearest tenth.
The property that is preserved under dilation is the similarity. The answer is letter A. Dilation of a figure starts from the very center of it and then continually increased or decreased depending on the desired size. It is similarity that is under dilation because no matter how big or small the size of the figure is, it has a similar feature from the original one.
Answer:
The coordinates of the P' point are (-17.3,-10).
Step-by-step explanation:
We can use the components of the vector from 0 to P point. We know that the diameter is 40 meters, so the magnitude of the vector will be 20 m.
Now, the angle from the negative x-direction to the vector is 210°-180° = 30°.
The x-component of the vector will be:


It is negative because the component is in the negative x-direction.
The y-component of the vector will be:


It is negative too because the component is in the negative y-direction.
Therefore, the coordinates of the P' point are P'(-17.3,-10)
