Step-by-step explanation:

1. Slope and the properties of perpendicular and parallel can be used to confirm that a polygon is a specific type of
quadrilateral.

What types of quadrilaterals can you determine by using these properties? List at least two types of quadrilaterals.

2. Choose one type of quadrilateral from your answer to Question 1. Explain in complete sentences how you can use
properties of perpendicular and parallel lines, together with slope, to confirm that a given polygon is the type of
quadrilateral you chose. Be sure to clearly state the properties that you need to use.

Please number your responses to the questions as they are shown (1 and 2).
NOTE from Ms. Kliban:
I found this answer on the Internet. *If it were an original answer, below is how I would grade it and why

1. The two would be rectangle and trapezium

2. You can determine with the properties that are given, that it's a polygon because with the slope already known that gives
a in to see which lines are perpendicular to which lines and which aren't. Also, with the properties you can tell if everything
Is parallel lines with the slope formula. Some slopes might be different but doesn't mean the polygon Isn't perpendicular
because two sides can have the same slope and the other two won't

GRADE: First off, in the United States, we don't use the word "trapezlum."
For part 2, it says, you can determine with the properties that are given." What properties? There are no properties given.
There are shapes. The next thing said in part 2 is that the slope is already known. No, it's not. You have to find the slope.

The grammar is bumpy. In other words, I stumbled over it when I tried to read it.
In order to do well on this assignment, part one only needs to have two quadrilaterals stated. You don't even have to have it

For part 2. you do need to use complete sentences. You need to explain how to find slope and why you need to find the
slope. Then also explain how parallel and perpendicular lines help you to make sure you have the shape you stated in part
sat

Answers

Answer: Rectangle and Trapezium

Step-by-step explanation:

If you have the slopes, then you can tell when two lines are parallel.

A rectangle has two pairs of parallel sides

A trapezium has exactly one pair of parallel sides

1.

We can determine whether a quadrilateral is a rectangle or a trapezium using the slope and the properties of parallel and perpendicular lines.

2. How are the slopes of perpendicular sides related?

Product of the slopes of perpendicular lines = -1.

M₁ * M₂ = -1 .

How are the slopes of parallel sides related?

Slopes of parallel lines are equal.

M₁ = M₂.

How do we determine a rectangle?

Suppose we have a quadrilateral ABCD.

AB and CD are one pair of opposite sides.

BC and DA are another pair of opposite sides.

AB is adjacent to BC. BC is adjacent to CD. CD is adjacent to DA. DA is adjacent to AB.

Slope AB = M₁

Slope BC = M₂

Slope CD = M₃

Slope DA = M₄

For ABCD to be a rectangle, by properties opposite sides need to be parallel and adjacent sides need to be perpendicular.

∴ If M₁ = M₃, M₂ = M₄ (for opposite sides to be parallel)

and if M₁.M₂ = -1, M₂.M₃ = -1, M₃.M₄ = -1, and M₄.M₁ = -1 (for adjacent sides to be perpendicular) then the given quadrilateral ABCD is a rectangle.

If the volume of a given cube is 729 cubic inches, what is the surface area of the
cube?
486 sq.inches
230 sq.inches
120 sq.inches
222 sq.inches

Answers

Answer:

SA = 486

Step-by-step explanation:

Its a cube. s = side length

V = [tex]s^{3}[/tex]

729 = [tex]s^{3}[/tex]

take cube root of each side : [tex]\sqrt[3]{729}[/tex] = 9

so,  s = 9

Surface Area of a cube

SA = 6[tex]s^{2}[/tex]

SA = 6([tex]9^{2}[/tex])

SA = 6(81)

SA = 486

The surface area of the cube is 486 square inches. The correct option is A.

To find the surface area of a cube, we need to use the formula:

Surface Area = 6 x (side length)²

Given that the volume of the cube is 729 cubic inches, we can determine the side length of the cube using the formula for volume:

Volume = (side length)³

729 = (side length)³

Taking the cube root of both sides:

side length = ∛(729) = 9 inches

Now, we can substitute the side length into the surface area formula:

Surface Area = 6 x (9 inches)² = 6 x 81 = 486 square inches

Therefore, the surface area of the cube is 486 square inches.
