The geometric sequence shown can be represented by the function y = (1/2) ^ n where the domain of the function is

Correct D

Step-by-step explanation:

Geometric Sequence

We can find each term of a geometric sequence if we have the general formula by replacing n for any integer number in the given domain. n must be an integer because it's the position where the term is located. For example, is the term located in position 2, so n cannot be irrational or decimal. The sequence provided is

The variable n starts from 0 and has no limit, so the domain is a set of integers

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
