Given the set of ordered pairs: {(1,3), (2,7), (x,5), (6,4)}.
MrMuchimi

Answer:

2

Step-by-step explanation:

2 is a value of x that would not make the set a function because a function can't have multiple coordinates wit hthe same domain (x-coordinate). 2 is a domain that has already been used in the point (2,7). If this is used in (x,5), the point would become (2,5) and repeat a domain.

Note:

The x-coordinate could also be 1 or 6 because they have been used as domains as well.

Hope it helps!

What is the area of a circle with a diameter of 6x? (Use 3.14 for R
aksik [14]
The area of a circle is defined as Pi R^2

Since we only have the diameter and Pi, we need to solve for the radius.

The radius is 1/2 of the diameter, so divide 6 by 2 to get our radius.
6 / 2 = 3

Our radius is 3.

Now let's plug in our formula.

A = 3.14 x 3^2

3 x 3 = 9
9 x 3.14 = 28.26

Your area is 28.26 units ^2

I hope this helps!

* Some amount of billiard balls were arranged in an equilateral triangle. And 5 balls were extra. When the same set of billiard
Agata [3.3K]

Lets say billiard balls are arranged in rows to form an equilateral triangle, then the first row consists of 1 ball, second row consists of 2 balls, and third row consists of 3 balls,  and so on. So there must be n balls in the n^{th} row.  

So, the total number of balls that forms the equilateral triangle with n rows is:  

1+2+3+4+5+....+n=\frac{n(n+1)}{2}

Let x_1 and x_2 be the total number of balls in the first and second arrangements respectively.  

Then,

x_1=\frac{n(n+1)}{2} +5

It has been said that there were 11 lesser balls in the second arrangement:  

x_2=\frac{1+(n+1)}{2} \times (n+1)-11=(n+1) \times \frac{(n+2)}{2} -11

Since, x_1=x_2

\frac{(n+1)}{2} \times n+5=\frac{(n+2)}{2} \times(n+1)-11

multiplying both the sides by 2

(n+1)\times n+10=(n+2)(n+1)-22

n+n^2=n^2+n+2n+2-22-10

2n=22+10-2

2n=30

n=15

Therefore,

x_1=\frac{(n+1)}{2}\times n+5=\frac{15+1}{2}  \times 15+5=125

So, there were 125 balls at the set.
