Create a graph that has the following intercepts. Make sure to label each of the intercepts on
SCORPION-xisa [38]

Answer:

  see below for the graph

Step-by-step explanation:

The desired graph has two y-intercepts and one x-intercept. It is not the graph of a function.

Here's one way to get there.

__

Start with the parent function y = |x| and scale it down so that it has a y-intercept of -1 and x-intercepts at ±1.

Now, it is ...

  f(x) = |x| -1

We want to scale this vertically by a factor of -5. this puts the y-intercept at +5 and leaves the x-intercepts at ±1.

Horizontally, we want to scale the function by an expansion factor of 3. The transformed function g(x) will be ...

  g(x) = -5f(x/3) = -5(|x/3| -1) = -5/3|x| +5

This function has two x-intercepts at ±3 and one y-intercept at y=5. By swapping the x- and y-variables, we can get an equation for the graph you want:

  x = -(5/3)|y| +5

______

<em>Comment on this answer</em>

Since there are no requirements on the graph other than it have the listed intercepts, you can draw it free-hand through the intercept points. It need not be describable by an equation.

The perimeter of a particular square and the circumference of a particular circle are equal. What is the ratio of the area of th
Tasya [4]

Ratio of the area of the square to the area of the circle is \frac{\pi}{4} : 1

In terms of fraction \frac{\pi}{4}

<em><u>Solution:</u></em>

Given that perimeter of a particular square and the circumference of a particular circle are equal

To find:  ratio of the area of the square to the area of the circle

Let the side of square be "a" and radius of circle be "r"

<em><u>The perimeter of square is given as:</u></em>

Perimeter of square = 4a

<em><u>The circumference of circle is given as:</u></em>

Circumference of circle = 2πr

From given,

perimeter of a particular square and the circumference of a particular circle are equal

perimeter of a particular square = circumference of a particular circle

4a = 2 \pi r\\\\a = \frac{\pi r}{2}

We need to find the ratio of the area of the square to the area of the circle.

We know that,

\text{ Area of the square }= a^2\\\\\text{ Area of the circle }= \pi r^2

Ratio of area of square to area of circle = a^2 : \pi r^2

Substituting the value of a = \frac{\pi r}{2} in above ratio,

Ratio of area of square to area of circle = (\frac{\pi r}{2})^2 : \pi r^2

On reducing to lowest terms we get,

⇒ \frac{\pi^2 r^2}{4} : \pi r^2 = \frac{\pi}{4} : 1

In terms of fraction we get,

\frac{\pi}{4} : 1 = \frac{\frac{\pi}{4}}{1} = \frac{\pi}{4}

Thus ratio of the area of the square to the area of the circle is \frac{\pi}{4} : 1
