Answer:
He should travel directly
Step-by-step explanation:
Given
--- East
--- North
If he goes through east north direction, the distance (d) traveled is:
If he travels directly, the distance (d) is:
---- Pythagoras theorem
By comparison, he will travel the shortest distance if he travels directly because
<em>Hence, he should travel directly</em>
The scale factor that was applied to figure A to produce figure B is: 11/3 = 3.67.
<h3>How to Find the Scale Factor of a Dilation?</h3>The ratio of the corresponding dimensions of the image to the preimage gives the scale factor of any dilation.
That is:
Scale factor = dimension of image (new figure) / corresponding dimension of pre-image (original figure).
The scale factor that was applied to figure A to produce figure B = dimension of figure B / corresponding dimension of figure A.
A dimension of figure B = 33
Corresponding dimension of figure A = 9
Therefore, we would find the scale factor as shown below:
The scale factor that was applied to figure A to produce figure B = 33/9
= 11/3 = 3.67
Therefore, the scale factor that was applied to figure A to produce figure B is: 11/3 = 3.67.
