Find the midpoint of the segment with the following endpoints. (3, 2) and (9, 6)
myrzilka [38]

Answer:

The answer is

<h2>( 6 , 4 )</h2>

Step-by-step explanation:

The midpoint M of two endpoints of a line segment can be found by using the formula

M = (  \frac{x_1 + x_2}{2} , \:  \frac{y_1 + y_2}{2} )\\

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(3, 2) and (9, 6)

The midpoint is

M = ( \frac{3 + 9}{2}  \:  , \:  \frac{2 + 6}{2} ) \\  = ( \frac{12}{2}  \: , \:  \frac{8}{2} )

We have the final answer as

<h3>( 6 , 4 )</h3>

Hope this helps you

Which table contains the vertex of the graph represented by y=x^2-6x+4?
notka56 [123]

Answer:

Table B

Vertex is (3,-5)

Step-by-step explanation:

We are given with an equation of a parabola y=x^2-6x+4

Let is convert it into standard form of a parabola

y=x^2-6x+4

adding and subtracting 9 in the right hand side of the =

y=x^2-6x+9-9+4

y=x^2-2\times 3\times x+ 3^2-9+4

the first three terms of the right hand side forms the expression of square of difference

a^2-2 \times a \times b+b^2 = (a-b)^2

Hence

y=(x-3)^2-5

adding 5 on both sides we get

(y+5)=(x-3)^2

Comparing it with the standard equation of a parabola

X^2=4\times \frac{1}{4} \times Y

where X=x-3 and Y=y+5

The vertex of X^2=4\times \frac{1}{4} \times Y will be (0,0)

and thus vertex of

(y+5)=(x-3)^2 will be (3,-5)

Hence the Table B is our right answer
