What is the equation for the hyperbola shown?

Mathematics
1 answer:
castortr0y [4]2 years ago
7 0

Answer:

\frac{x^{2} }{3600} - \frac{y^{2} }{121} = 1

Step-by-step explanation:

Since the hyperbola opens left and right with a center at the origin, then

\frac{x^{2} }{^{2} } - \frac{y^{2} }{b^{2} } = 1

In the graph a = 60 and b = 11

So

\frac{x^{2} }{60^{2} } - \frac{y^{2} }{11^{2} } = 1.

\frac{x^{2} }{3600} - \frac{y^{2} }{121} = 1

A box contains 500 marbles. The result of 20 marbles pulled at random from the box is given below.
Anni [7]

Answer:

100 black marbles

Step-by-step explanation:

The experimental probability of a black marble is

P(black) = 4/20 = 1/5

We expect that out of the 500 marbles in the box, 1/5 of them are black

1/5 (500) = 100

There should be 100 black marbles

Dan Stocked up on batteries. He Brought 10 packages of AA and AAA batteries for a total of 72 batteries. The AA batteries are so
LuckyWell [14K]

Answer:

The system of equations that make the definition are;

x + y = 10 •••••••••(i)

6x + 8y = 72 ••••••••(ii)

Where x refer to the number of packages of AA battery bought and y refers to the number of packages of AAA batteries bought

Step-by-step explanation:

Here, we are to write system of equations that can be solved which will help give the number of packages of each type of battery bought.

Let the number of AA batteries bought be x while the number of AAA batteries bought be y;

Since he bought a total of 10 packages,

What this means is that;

x + y = 10 •••••••••(i)

We are also told that the AA batteries are sold in packages of 6, so the total number of AA batteries bought is; 6 * x = 6x

Also, we know that the AAA batteries are sold in packages of 8, so the total number of AAA batteries bought is 8 * y = 8y

We add both to give the total number of packages.

Mathematically, that would be;

6x + 8y = 72 •••••••••(ii)

By solving both equation set, we shall have the number of each types of batteries bought
