Does the relationship {(1,1), (2,1),(3,2), (4,3), (5,5), (6,8), (7,13)} represent a function?

Answer:

Yes.

Step-by-step explanation:

A function is a set of relations without repetitive domains.

From the given relation, there are no repetitive domains. Thus our relation here is a function.

<u>Example</u><u> </u><u>of</u><u> </u><u>Function</u>

{(1,1), (2,2), (3,3), (4,4), (5,5)}

<u>Example</u><u> </u><u>of</u><u> </u><u>Non-Function</u>

{(1,1), (1,2), (2,3), (3,4), (4,5)}

From this relation, there are two repetitive domains which are 1's. Thus not making the relation a function.

Can some one answer this plz ill give !100 POINTS!
Lorico [155]
Hello!

First of all let's find the perimeter (circumference) of the semi circles. We can combine them to make one circle with a diameter of 4 (as we can see the side length of one semi circle is 4 cm. We now plug it into the circumference equation (\pi=3.14).

4(3.14)=12.56

Now we add up the side lengths of the rectangle.

4+6+4+6=20

Now we add up the length of our circle and rectangle.

20+12.56=32.56

Therefore our answer is 32.56 cm.
----------------------------------------------------------

Now to find the area! If we combine the two semicircles, we get a circle with a diameter of four. This means that is has a radius of two. We use the equation below to find the area of the two circles.

A=\pir²

First we will square our radius.

2(2)=4

Now we multiply by pi.

4(3.14)=12.56

Now we need to find the area of the rectangle.

6(4)=24

Now we add.

24+12.56=36.56.

 
I hope this helps!

Answer:

7/5

Step-by-step explanation:

Ⓗⓘ ⓣⓗⓔⓡⓔ

Well, slope can be found using

y2-y2

x2-x1

So we just plug it in:

7-0

2+3

7/5 is your slope
