State the domain and range of the given relation. {(-1,2),(1,2),(3,2),(6,2)}

Andru [333]

Step-by-step explanation: In this problem, we're asked to state the domain and range for the following relation {(-1,2), (1,2), (3,2), (6,2)}.

Let's go over a few vocabulary words and

these are domain, range, and relation.

So let's start with the word relation.

A relation is simply a set of ordered pairs like you see here.

The domain is the set of all x-coordinates for those ordered pairs.

So in this case, the domain is -1, 1, 3, and 6.

We can write this as {-1, 1, 3, 6}.

The range is the set of all y-coordinates for those ordered pairs.

So in this case our range is 2, 2, 2, and 2.

Notice that the y-coordinate of 2 is

repeated in three of our ordered pairs.

In this situation, we only need to mention it once in our range.

So our range is {2}.

The perimeter of a quadrilateral (four-sides polygon) is 50 inches. The longest side is three times as long as the shortest side

kkurt [141]

The side lengths of quadrilateral are 21 inches; 11 inches; 11 inches; 7 inches.

SOLUTION:

Given, the perimeter of a quadrilateral (four-side polygon) is 50 inches.

Let the length of shortest side be n inches. The longest side is three times as long as the shortest side.

That is, length of largest side = 3n inches

The other two sides are equally long and are 4 inches longer than the shortest side.

Then, length of remaining two sides = 4 + n inches

We have to find the length of all four sides.

Now, we know that, perimeter = 50 inches

$\begin{array}{l}{\rightarrow \text { Sum of all sides }=50} \\\\ {\rightarrow n+3 n+n+4+n+4=50} \\\\ {\rightarrow n+3 n+n+n=50-4-4} \\\\ {\rightarrow 6 n=42} \\\\ {\rightarrow n=7}\end{array}$

So, length of sides will be,

$7 \text { inches; } 3\times7=21 \text { inches; } 7+4=11 \text { inches; } 7+4=11 \text { inches. }$

What is the length of segment AC

lakkis [162]

To find the length of segment AC, we must find the total rise and total run between the two points.

Point C is located at (-5, 5). Point A is located at (3,-1). To find the rise, subtract the y-value of A from the y-value of C:

$5 - (-1) = 6$

The rise of this segment is 6.

To find the run, subtract the x-value of A from the x-value of C:

$3 - (-5) = 8$

The run of this segment is 8.

We can use the Pythagorean Theorem to find the length of this segment. The theorem uses the following formula:

$a^{2} + b^{2} = c^{2}$

The segment represents the hypotenuse, and the rise and run represent the legs of this segment. We know that the two legs' lengths are 6 and 8, so plug them into the equation:

$6^{2} + 8^{2} = c^{2}$
$36 + 64 = c^{2}$
$100 = c^{2}$

Square root both sides to get c by itself:

$\sqrt{100} = 10$
$c = 10$

The length of segment AC is 10.
