Answer:

A relation is a function if x values never repeat, so every input will only have one output. If the function is graphed you can do the vertical line test, a relation passes if you can draw a vertical line anywhere on the graph and it only intersects with the relation once.

Answer:

7.9 ft

Step-by-step explanation:

The hypotenuse is the side opposite of the right angle, hence the hypotenuse for this triangle is 11 ft.

Side $x$ is adjacent to the angle given. So we need adjacent and we have hypotenuse. Which trigonometric ratio relates adjacent and hypotenuse? It is COSINE.
