Answer:

The one in the bottom right that is an absolute value function.

Step-by-step explanation:

You can use the "vertical line test" to determine whether a given graph is a function or not. If you can draw a straight, vertical, line anywhere and it intersects the graph more than once, then it is not a function. The one in the bottom right is therefore the answer.

The square has a radius of 3 square root 2 what is the apothem?

Mrrafil [7]

The diagram of the square is shown in the first picture below

We have the radius $3 \sqrt{2}$ and the triangle formed is an isosceles triangle

We can start by finding out the length of one side of the square. A square has four sides of equal length and the length of the diagonal is twice the length of the radius. So, by using the Pythagoras theorem we have

$(2r)^{2} = a^{2}+ a^{2}$
$4 r^{2} =2 a^{2}$ , substitute $r=3 \sqrt{2}$
$4 (3 \sqrt{2}) ^{2} = 2 a^{2}$
$4(18) = 2 a^{2}$
$72=2 a^{2}$
$a^{2}= \frac{72}{2}$
$a^{2}=36$
$a=6$

Then we'll use Pythagoras theorem again to find the length of the Apothem

We need to halve the length of one side of the square to obtain the other short side of the right angle triangle, so 6÷2 =3

apothem² = (3√2)² + 3²
apothem² = 18+9
apothem² = 27
apothem = √27 = 3√3
