Point (20, 5) is on the graph of inverse variation. Which of the following ordered pair is on the graph?.

Bess [88]

The point $(10, 10)$ is on the graph.

<h3>Procedure - Inverse variation</h3><h3 /><h3>Inverse variation model</h3><h3 />

An <em>inverse</em> variation is represented by the following formula:

$y = \frac{k}{x}$ (1)

Where:

$x$ - Independent variable.
$y$ - Dependent variable.
$k$ - Proportionality constant.

We can eliminate the proportionality constant by creating the following relationship:

$x_{1}\cdot y_{1} = x_{2}\cdot y_{2}$ (2)

<h3>Determination of another point</h3>

If we know that $x_{1} = 20$ , $y_{1} = 5$ and $x_{2} = 10$ , then the remaining variable is:

$y_{2} = \left(\frac{x_{1}}{x_{2}} \right)\cdot y_{1}$

$y_{2} = \left(\frac{20}{10} \right)\cdot (5)$

$y_{2} = 10$

The point $(10, 10)$ is on the graph. (Correct choice: C) $\blacksquare$

What does the evolution in how we understand the identities of superman suggest about how society's view of identity changed ove

wlad13 [49]

There has been several evolution overtime. The one that tells how we understand the identities of Superman suggests that society's view of identity is known to be subjective.

Here, the society takes identity at face value instead of the use of other form of evidence.

<h3>Why a subjective view?</h3>

From the study of the Superman's secret identity and its evolution, it therefore shows how the society really see the idea about identity.

Note that Clark Kent in the story has the same resemblance to Superman but they are of two identities types.

People often can see and accept one of the identity type they conform to them and ignore any kind of anomaly such as that of superman. So we can say that they are two different persons living two different lives.
