Which image shows triangle ABC dilated by a scale factor of 3 centered at the point B
1 answer:
If triangle ABC undergoes a dilation of scale factor 3 centered at the origin, the coordinate of the image of point B is known to be option D. (6,9).
<h3>What is the dilation about?</h3>The term Dilation is known to be a kind of a transformation, that is used to change the size of an object.
Note that Point B has coordinates of (2, 3)
So the Dilation factor 3 will alter the coordinates as:
(2*3, 3*3)
= (6, 9)
Hence, If triangle ABC undergoes a dilation of scale factor 3 centered at the origin, the coordinate of the image of point B is known to be option D. (6,9).

The displacement of the girl which the relative change in her position from her starting point. Therefore, the shortest distance between her initial and final position is 58.85 m North - West
From the sketch of the girls movement attached below, the displacement of the girl can be calculated thus :
Using Pythagoras :
Displacement, d = √(50² + 20²)
d = √(2500 + 400)
d = √2900
d = 53.851
Therefore, the displacement of the girl, which is the shortest distance between her current position and starting position is 53.85 meters NW.
