Your visually impaired friend asked you to enlarge your notes from class so he can study. You took notes on 8.5-inch by 11-inch paper.
The enlarged copy has a smaller side with a length of 10 inches. What is the scale factor of this dilation?

Respuesta :

The scale factor of the dilation of the note is; S.f = 1.176

The dimensions of the original note is; 8.5-inch by 11-inch.

  • However, the enlarged copy has a smaller side with a length of 10 inches.

In essence, the scale factor of the dilation can be evaluated as follows;

  • Scale factor, s.f = (Enlarged small side)/(original small side)

Scale factor, s.f = 10/8.5

  • s.f = 1.176

Therefore, the scale factor of the dilation of the note is; S.f = 1.176
