Which equation represents a function?

Answers

Answer 1

Answer:

All the answers except C has a Vertical Line when graphed. It must pass the Vertical line test in order to be a function.

Vertical Line Test: If you can draw a vertical line anywhere on a graph so that it hits the graph in more than one spot, then the graph is NOT a function.

C.) can pass the test since it's a horizontal line.

Hope this helps!

The length of the hypotenuse of 30-60-90 triangle is 5. find the perimeter

Answers

Answer:

$7.5+2.5√(3)$

Step-by-step explanation:

The ratio of sides in a 30-60-90 triangle is $1:2:√(3)$ . Since the hypotenuse is the longest side, the shortest leg is 5/2=2.5. The leg that would usually be $√(3)$ is now $2.5√(3)\approx 4.33$ . Adding all of these together, you get $7.5+2.5√(3)\approx 11.83$ . Hope this helps!
