You know from the y-intercept that the equation will have a +y^2/12 term in it. Then for y=6, you have
.. 6^2/12 -x^2/b = 1
.. 2 = x^2/b
.. b = x^2/2
If your point is (2√3, 6), then this is
.. b = (2√3)^2/2 = 12/2 = 6

Then the hyperbola's equation is
.. y^2/12 -x^2/6 = 1 . . . . . . . . selection D

May I please receive help?

Answer:

\frac{10}{9}\pi      yards

Step-by-step explanation:

The circumference of this circle = 2πr

                                                     = 8π

We have to find the arc length of 50°, or 50/360 times the circumference of the circle(because there is 360° in a circle)

\frac{50}{360} * 8\pi = \\\\\frac{400\pi}{360} =\\\\ \frac{10\pi}{9}

If AC = x + 5 and AB = 3x - 1... what is the length of BC?
Hatshy [7]
If B is the midpoint of AC, then |AB| = |AC|.
|AB| = 3x + 2
|BC| = 5x - 10
Therefore we have the equation:
3x + 2 = 5x - 10     |subtract 2 from both sides
3x = 5x - 12      |subtract 5x from both sides
-2x = -12      |divide both sides by (-2)
x = 6

There are 52 playing cards in a standard deck of cards. If Patrica selects a card at random, what is the probability that it wil
Alisiya [41]
Since there are two black queens out of 52 cards, there is a 2/52 chance of drawing a black queen first.  This is equivalent to a 1/26 chance.

Now that we have removed a black queen, there are 51 cards left in the deck.  26 of them are red because we only took away a black card.  This means that there is a 26/51 of drawing a red card next.

In order to find the probability of both of these happening, we multiply the two together.  1/26 * 26/51 = 26/1326.  This reduces to 1/51.  So, there is a 1/51 chance of drawing a black queen, then a red card.
