Answer:

pie is equal to the square root of A divided by r

Step-by-step explanation:

Set the equation first...a=pie times r squared. Then u need to get rid of everything to make pie by itself. U square both sides or all the equation. the square cancels out and on the other side, it will be the square root of a. Next, divide by r on each sides. The r cancels out. Then it's gonna be pie =the square root of a all over r. It can't be a/r square because in the original...pie is being multiplied by r which is squared so that means both variables are squared. U cant find pie if the square is stopping it so u square for the very first step

13. Find the measure of angle ABC. B 8x 6x 6x A С​
Crazy boy [7]
<h2>Answer</h2>

Angle A = 54 degree

Angle B = 72 degree

Angle C = 54 degree

<h2>Explain</h2>

It is a triangle, so the total of angle is 180 degree

Find X

8x + 6x + 6x = 180

20x = 180

x = 180/20

x = 9°

Value of x is 9°

Substitute a score of x for every angle =

Angle A

= 6x

= 6(9)

= 54°

Angle B

= 8x

= 8(9)

= 72°

Angle C

= 6x

= 6(9)

= 54°

Each graph shows a relation. The first and second numbers of each ordered pair in the relation are members of the set of real nu
Goshia [24]

Using it's concepts, we have that:

  • The domain of the relation is of -2 ≤ x ≤ -1.
  • The range of the relation is of -2 ≤ y ≤ 2.
  • Since each value of the input is mapped to only one value of y, it is a function.

<h3>What are the domain and the range of a relation?</h3>

  • The domain of a relation is the set that contains all possible input values for the relation. In a graph, it is given by the values of x.
  • The range of a relation is the set that contains all possible output values for the relation. In a graph, it is given by the values of y.

Hence:

  • The domain of the relation is of -2 ≤ x ≤ -1.
  • The range of the relation is of -2 ≤ y ≤ 2.

<h3>When does a relation represents a function?</h3>

A relation represents a function when each value of the input is mapped to only one value of the output.

From this graph, we have that <u>each value of x is mapped to only one value of y</u>, that is, there are no vertically aligned points, hence the relation is a function.
