Without any equipment you can see stars that are 2,800,000 light years away. By looking at through a small telescope you can see the stars that are 3,112,000,000 light years away. Approximately how many times as far can you see using a small telescope as without any equipment. A. 1x 10^2
B. 3x 10^2
C. 1x 10^3
D. 3x 10^3

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl

y=sec x is the correct answer
