What is the equation for the hyperbola shown?

Mathematics

Answer:

D. y²/5² - x²/8² = 1

Step-by-step explanation:

From the graph of the hyperbola, we can see that points (0,5) and (0,-5) form part of the hyperbola.

This means that the equation of the hyperbola should be satisfied by these points.

Substituting x=0 and y=5 in the given options:

A. LHS = -1 while RHS = 1

B. LHS = \[\frac{-5^{2}}{8^{2}}\] while RHS = 1

C. LHS = \[\frac{5^{2}}{8^{2}}\] while RHS = 1

D. LHS = 1 and RHS = 1

So only option D contains the point (0,5).

Now verifying option D for the point (0,-5):

LHS = 1 and RHS = 1

So equation D is the correct equation for the hyperbola.

Answer:

D. y²/5² - x²/8² = 1

Step-by-step explanation:

A and B are both incorrectly oriented, and D is the only hyperbola that contains the points (0,5) and (0,-5).

Verification (0,5) and (0,-5) are in the hyperbola:

First replace x and y with corresponding x and y values (We will start with x=0 and y=5)

\frac{5^{2}}{5^{2}}-\frac{0^{2}}{8^{2}}=1

Then simplify.

\frac{25}{25}-\frac{0}{16}=1

1-0=1

1=1

If the result is an equation (where both sides are equal to each other) then the original x and y values inputted are valid. The same is true with x and y inputs x=0 and y=-5, or any other point along   the hyperbola.

Step-by-step explanation:

Rate of change = final - initial / time(in years)

= 41 - 43 / 2014 - 2012

= - 2 / 2

<u>Rate of change</u> = <u>- 1</u>

Therefore, the number of employees with health care benefits reduced by 1 person per year between 2012 - 2014 in response to policy changes.

The equation y = 1.55x + 110,419 approximates the total cost, in dollars, of raising a child in the United States from birth to
Mariana [72]

Answer:

The answer to your question is The cost to raise a child from birth to 17 years in a household is $194119.

Step-by-step explanation:

Equation

                      y = 1.55x + 110,419

Annual income = $54,000

To solve this problem just substitute the annual income and simplify to find the cost.

                    y = 1.55(54,000) + 110419

Simplify

                    y = 83700 + 110419

Result

                    y = $194119
