Answer:

$1/16$

Step-by-step explanation:

The formula for the sequence $a_n=\frac{1}{2}^n$ is used to find the $n$ th term of the sequence.

To find the fourth term, substitute $n=4$ :

$a_4=\left(\frac{1}{2})\right ^4,\\a_4=\frac{1^4}{2^4}=\boxed{\frac{1}{16}}$

What is the solution set

Free_Kalibri [48]

We graphically solve $f(x)=g(x)$ by graphing $f(x)$ and $g(x)$ and eyeballing the points where they intersect each other.

Really none of our choices are the solution set listing all the (x,y) pairs where the two functions meet because none of them is a set.

Anyway we count from the origin five to the right and three up to the meet of the lines, which is the point $(5,3)$ , last choice.
