Is x^2+y^2=5 a function? why or why not?

Mathematics
1 answer:
ZanzabumX [31]3 years ago
7 0

Answer:

No.

Step-by-step explanation:

A function must past the Vertical Line Test. We know that our equation x² + y² = 5 is a circle, and so some x-values have the same y-values, etc. Since not every x-value has its own y-value, our equation is <em>not</em> a function.

We can see this using a graph:

Since the vertical line test passes 2 points with the same x-value, it is not a function.

irrational number, any real number that cannot be expressed as the quotient of two integers.

Any number that can be written as a fraction with integers is called a rational number . For example, 17 and −34 are rational numbers. (Note that there is more than one way to write the same rational number as a ratio of integers.

1st Is rational

2nd one is irrational

3rd is irrational

4th is rational

My teacher wouldn't help me.. and this is my last question. I need to know how to find the perimeter of the geometric figure (it
nika2105 [10]
This isn't really a geometry problem.  It's just an addition of fractions.

You know that 'perimeter' means 'the distance all the way around'.
And you know the length of all the sides of the parallelogram.
All you need to do is add them up !

(13/12) + (3/13) + (13/12) + (3/13) = the perimeter

Notice that two of the sides are equal, and the other two sides are also equal.
So you can make the job a little easier if you add up the twelfths first

(13/12) + (13/12) = 26/12

and then add up the thirteenths ...

(3/13) + (3/13) = 6/13 .

Now, the perimeter looks a little bit less complicated.
It's just
                   (26/12) + (6/13) = the perimeter.

This is the tough part.  Before you can add fractions, they need to have
a common denominator. 

The smallest common denominator for 12ths and 13ths is  <em>156 </em>!
Change each fraction to (<em>something over 156</em>), and add um up.
I'll leave that part to you.
