Question

The pupil is the circular opening that allows light into the eye. An optometrist dilates a patient's pupil from 6 mm to 8 mm. The scale factor under this dilation is ?

Answer 1

Answer:

4/3

Step-by-step explanation:

Scale factor is a ratio of the length of side in one object to the length of a corresponding side of the other object.

In this case, the scale factor will be the ratio of the new dilated pupil size of the patient to the previous size of the pupil

This will be : 8/6 = 4/3

The scale factor is : 4/3
