(3,6) (3,7) (-2,-5) (-9,11) is it a function a relation, or both

Answers

Answer 1
Answer:

It is a relation but not a function

Step-by-step explanation:

Given

(3,6) (3,7) (-2,-5) (-9,11)

First of all we have to define both terms: Relation and Function

A relation is a set of ordered pairs containing one element from each set

A relation can be a function only if there is no repetition in domain i.e. no first element in each ordered pair should be repeated.

In the given set of ordered pairs, they are relation as all the ordered pairs have two values.

While the given relation is not a function, as there is repetition in first elements of two ordered pairs i.e. 3 is repeated in (3,6) (3,7)

Hence,

It is a relation but not a function

A cylinder is full at 471 cm3 and has a radius of 5 cm. It currently contains 314 cm3 of water. What will the difference in the height of the water be when the cylinder is full? Use 3.14 to approximate pi.

Answers

Volume of a cylinder = π r² h

fully filled w/ water:
471 cm³ = 3.14 * (5cm)² * h
471 cm³ = 3.14 * 25cm² * h
471 cm³ = 78.5 cm² * h
471 cm³ / 78.5 cm² = h
6 cm = h  

partially filled with water
314 cm³ = 78.5cm² * h
314 cm³ / 78.5 cm² = h
4 cm = h

6 cm - 4 cm = 2 cm the difference in the height of the water.

Is 5622 divisible by 4

Answers

Well it's 1,405.5 so no

Actually no because when we divide 5622/4 = 2811/2. So it is not divisible.

What is the value of x? 12-x=7

Answers

Answer: The value of x = 5.


Step-by-step explanation:

Given linear equation is 12-x=7 with variable x

To find the solution i.e. the value of x of the given linear equation, we need to perform following steps:

Step 1. Subtracting 12 from the both sides of the equation,we get

⇒12-x-12=7-12

⇒-x=-5

Step 2. Multiplying (-1) on the both sides ,we get

⇒-x × -1=-5 × -1

⇒x=5

So ,the value of x=5

Thus required solution of the given linear equation is x=5.

12-x=7. Well if you look at seven you should Be able to subtract 7 from 12 and get five.


You x Value = 5!
