Answer:

C

Step-by-step explanation:

The right triangle on the right side of the figure has a height of 6 (two same sides lengths) and a base of 3.

x is the hypotenuse (side opposite of 90 degree angle).

We can use the pythagorean theorem to find x. The pythagorean theorem tells us to square each leg (height and base) of the triangle and add it. It should be equal to the hypotenuse square.

For this triangle it means, we square 6 and 3 and add it. It should be equal to x squared. Then we can solve. Shown below:

6^2 + 3^2 = x^2\\36 + 9 = x^2\\45 = x^2\\x=\sqrt{45}

<em>Now we can use property of radical  \sqrt{x}\sqrt{y}  =\sqrt{x*y}  to simplify:</em>

x=\sqrt{45} \\x=\sqrt{5*9} \\x=\sqrt{5} \sqrt{9} \\x=3\sqrt{5}

Correct answer is C

Is the relation a function? <br><br> {( 1, 12), (3, 14), (14, 3), (5, 12)}<br><br> yes or no
Iteru [2.4K]

Answer:

Yes.

Step-by-step explanation:

Yes because each  value of x maps to a single value of y.

THere is a many-to-one relation with (1, 12) and (5, 12) but that is OK  for a function.  What would not be OK  is if we had a one-to-many relation like  (1, 12) and (1, 14)  included in the ordered pairs - that is not a function.
