Three vertices of a parallelogram are shown in the figure below.
Give the coordinates of the fourth vertex.
(-3,9)
(0,-3) (6,-6)

Answers

Answer 1

Given:

The three vertices of the parallelogram are (-3,9), (0,-3), (6,-6).

To find:

The fourth vertex of the parallelogram.

Solution:

Consider the three vertices of the parallelogram are A(-3,9), B(0,-3), C(6,-6).

Let D(a,b) be the fourth vertex.

Midpoint formula:

[tex]Midpoint=\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)[/tex]

We know that the diagonals of a parallelogram bisect each other. So, the midpoints of both diagonals are same.

Midpoint of AC = Midpoint BD

[tex]\left(\dfrac{-3+6}{2},\dfrac{9+(-6)}{2}\right)=\left(\dfrac{0+a}{2},\dfrac{-3+b}{2}\right)[/tex]

[tex]\left(\dfrac{3}{2},\dfrac{3}{2}\right)=\left(\dfrac{a}{2},\dfrac{-3+b}{2}\right)[/tex]

On comparing both sides, we get

[tex]\dfrac{3}{2}=\dfrac{a}{2}[/tex]

[tex]3=a[/tex]

And,

[tex]\dfrac{3}{2}=\dfrac{-3+b}{2}[/tex]

[tex]3=-3+b[/tex]

[tex]3+3=b[/tex]

[tex]6=b[/tex]

Therefore, the fourth vertex of the parallelogram is (3,6).

Step-by-step explanation:

According to Triangle Sum Theorem, the 3 interior angles of a triangle adds up to 180 degrees.

So, you can take the other 2 interior angles to find the third on:

180-72-35=73

<1=73 degrees

Answers

Given:

17 quarts of soil are used to completely fill 4 flower pots.

To find:

The number of quarts hold by each pot if each pot holds the same amount of soil.

Solution:

Let [tex]x[/tex] be the number of quarts hold by each pot.

Total number of quarts hold by 4 flower pots = [tex]4x[/tex]

It is given that, 17 quarts of soil are used to completely fill 4 flower pots.

[tex]4x=17[/tex]

[tex]x=\dfrac{17}{4}[/tex]

[tex]x=4.25[/tex]

Therefore, the each pot holds 4.25 quarts of soil.

What’s the volume of the prism ?

Answers

Answer:

63[tex]cm^{3}[/tex]

Step-by-step explanation:

To find the volume of this prism, all you need to do is multiply the height, the width, and the length of the prism. The height is 3, the length is 7, and the width is 3. So 3·3·7=9·7=63. Now we have to add the label, which is cm. We are multiplying 3cm by 3cm by 7cm, which makes it  [tex]cm^{3}[/tex]. Now you just multiply [tex]cm^{3}[/tex] and 63 together, which gets you 63[tex]cm^{3}[/tex].

Answers

Answer:

The half of the moon facing the sun is always lit, but the different phases we view from Earth happen because:

we only see parts of the lit side as the moon goes around the Earth.

Step-by-step explanation:

The moon phases occur because the Sun lights different parts of the Moon as the Moon revolves around the Earth. So, we only see the parts of the Moon that are being lit while it orbits Earth.

Simplify the expression:

Answers

Answer:

4m + 6  

Step-by-step explanation:

Hello There!

We can simplify the expression by distributing the 2 to what is inside of the parenthesis ( 3 and 2m)

3 * 2 = 6

2 * 2m = 4m

so the expression 2(3 + 2m) simplified would be

4m + 6  

Answer: 6+4m

Step-by-step explanation:

Let's take our equation first

2(3+2m)

Now we need to distribute the 2 into the parenthesis'

This would mean we need to multiply 2 by 3 and 2m

our answer would be

6+4m
