Use the vertical-line test to determine whether the relation is a function. If not, identify two points a vertical line would pa
kicyunya [14]

Answer:

  not a function; (2, -2) and (2, 2)

Step-by-step explanation:

A vertical line has the same x-value for all of its y-values. Only the last answer choice lists two points on a vertical line. They also happen to be points on the graph, so it is NOT a function.

__

Any vertical line in the x-interval (-3, 3) will pass through the segments y=-2 and y=2. Vertical lines at x=-3 or x=3 will pass through an infinite number of points between y=-2 and y=2.

What is the probability that from a normal 52 card deck, you randomly draw a 5, and then without replacement, you select a Queen
Mamont248 [21]

Answer:

1 / 663

Step-by-step explanation:

First, let's find the total number of ways you can pick 2 cards from the deck. This is 52 * 51 = 2652 because there are 52 cards available for your first pick, and after you pick one, you'll have 51 left for your second pick.

There are 4 5's  (one for every suite) and only 1 Queen of Hearts in a deck of cards. Therefore, the total number of successful outcomes will be 4 * 1 = 4.

The probability of picking a 5 and then a Queen of Hearts is 4 / 2652 =

1 / 663. Hope this helps!

After joining two pieces of a picture frame together, a frame maker checks her work by measuring the diagonal (see the illustrat
tigry1 [53]
The diagonal (hypotenuse) is 13 in.

You need to use the Pythagorean Theorem

{a}^{2} + {b}^{2} = {c}^{2}
then just plug in the numbers and solve for c.

{12}^{2} + {5}^{2} = {c}^{2}
\sqrt{169} = c
13 = c
