Which of the following is the equation for the graph shown?
Nina [5.8K]

The equation of the hyperbola is \frac{x^2}{4} -\frac{y^2}{12} = 1

<h3>How to determine the equation of the graph?</h3>

The points on the graph are given as:

  • (2, 0) and (-2, 0)
  • (4, 0) and (-4, 0)
  • Lines at: x = 1 and x = -1

The hyperbola can be represented as:

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

The points (2, 0) and (-2, 0) means that:

b = \±2

Square both sides

b^2 = 4

So, we have:

\frac{x^2}{4} -\frac{y^2}{a^2} = 1

Also, we have:

a^2 = c^2 - b^2

Where c = 4

This gives

a^2 = 4^2 - 4

Evaluate

a^2 = 12

Substitute a^2 = 12 in \frac{x^2}{4} -\frac{y^2}{a^2} = 1

\frac{x^2}{4} -\frac{y^2}{12} = 1

Hence, the equation of the hyperbola is \frac{x^2}{4} -\frac{y^2}{12} = 1

(PLEASE ANSWER + BRAINLIEST ANSWER!!)
murzikaleks [220]

The arc length, radius and the included angle are related as

r\theta=\widehat {XYZ} where \theta is in radians.

The radius r is given by

r=\frac{\widehat {XYZ} }{\theta} \\ r=\frac{10.8}{1.8} \\ r=6\;units

Correct choice is (B).

Select the graph that would represent the best presentation of the solution set. | 5x -1 | &lt; 1
Alexxx [7]

Answer:

the absolute value of x is greater than 1/2, meaning that x is either greater than 1/2 or x is less than -1/2 (in this case, even though the numbers are decreasing or getting more negative, their absolute values are greater than 1/2). this is all i can tell you because you didn't give me any graphs.
