If R= {(1,2), (3,4), (5,6), (8,9)} find the domain and range of R a. Find value of X and Y.​
podryga [215]
<h2>The Domain and Range of a Set of Ordered Pairs</h2><h3>Answer:</h3>

Domain: x \in \{ 1, 3, 5, 8 \}

Range: y \in \{ 2, 4, 6, 9 \}

<h3>Step-by-step explanation:</h3>

We are given the set of ordered pairs: R. The Domain is just the set containing all the x values of each ordered pair of R. Recall that in the ordered pair (a,b), a is the x value. In set R, we can see that the x values are \{ 1, 3, 5, 8 \}.

For the Range, it is just the set containing all the y values of each ordered pair of R. Recall that in the ordered pair (a,b), b is the y value. In set R, we can see that the y values are \{ 2, 4, 6, 9 \}.

Write the equation of a circle for which the endpoints of a diameter are (-2,-2) and (4,-10)
Maurinko [17]

Answer:

Therefore the required Equation of Circle

x^{2}+y^{2}-2x+12y+12=0

Step-by-step explanation:

Given:

End point of Diameter be

point A( x₁ , y₁) ≡ ( -2 ,-2 )

point B( x₂ , y₂) ≡ ( 4 , -10 )

To Find:

Equation of a circle =?

Solution:

When end points of the Diameter are A( x₁ , y₁) , B( x₂ , y₂). then the Equation of Circle is given as

(x-x_{1})(x-x_{2})+(y-y_{1})(y-y_{2})=0

Substituting the end point are

(x-(-2))(x-4)+(y-(-2))(y-(-10))=0\\(x+2))(x-4)+(y+2))(y+10))=0\\

Applying Distributive Property we get

x^{2} -2x-8+y^{2}+12y+20 =0\\\\x^{2}+y^{2}-2x+12y+12=0

Therefore the required Equation of Circle

x^{2}+y^{2}-2x+12y+12=0
