Alfred is practicing typing. the first time he tested himself, he could type 27 words per minute. after practicing for a week, he could type 29 words per minute. after two weeks he could type 31 words per minute. based on this pattern, predict how fast alfred will be able to type after four weeks of practice.

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
