Answers

Answer:

line and point

Step-by-step explanation:

The kind of symmetry the figure given above posses is a line and point symmetry.

What is point symmetry?

A point Symmetry also known as origin symmetry is a Symmetry which occurs when every part of an object has a matching part. That is, the same distance from the central point but in the opposite direction.

Given that;

The objects looks the same when viewed from opposite directions.

We know that;

A line of symmetry is a line that cuts a shape exactly into two equal half. That is, if you fold the shape along the line, both halves would match exactly.

Therefore, the figure given above has both point and line Symmetry.

in 1-3 sentences, explain how we know that the the volume of a pyramid is V=1/3Bh

Answers

Answer:

The formula for finding the volume of a pyramid is V= lwh/3. Taking this into consideration, the length times the width times the height must be one, so we put that over three.

Step-by-step explanation:

The formula for the volume of a pyramid V=1/3Bh can be derived by dividing the pyramid into three identical triangular prisms, each with height h and base area B, and then calculating the total volume of the three prisms.

What is volume?

Volume is defined as the mass of the object per unit density while for geometry it is calculated as profile area multiplied by the length at which that profile is extruded.

Here,
The volume of a pyramid can be derived by considering that a pyramid is made up of a series of triangular cross-sections stacked on top of each other. The area of each triangular cross-section (the base) is given by the formula B = 1/2bh, where b is the base length and h is the height of the triangle. By multiplying the base area B by the height h of the pyramid and then dividing by 3 (to account for the triangular shape), we get the formula V = 1/3Bh for the volume of a pyramid.

WILL MARK BRAINLIEST Which table represents a relation with a domain of (-1, 2} and a range of (3,5)?

Answers

Answer:

Step-by-step explanation:

Second table represents the relation with a domain of {-1, 2} and a range of {3, 5}.

What do you mean by domain and range of a function?

For any function y = f(x), Domain is the set of all possible values of y that exists for different values of x. Range is the set of all values of x for which y exists.

Given is a relation with a domain of (-1, 2) and a range of (3, 5)

It can be seen that second table represents the relation with a domain of {-1, 2} and a range of {3, 5}.

Therefore, second table represents the relation with a domain of {-1, 2} and a range of {3, 5}.

The Composite figure is made up of a Triangle, and a trapezoid. What is the area of the composite figure?

Answers

Answer:

I DON'T KNOW the answer but hears the explanation.

Step-by-step explanation: So the total area of the composite shape is 30 + 20 = 50 cm². Note: An alternative method is to use the formula for the area of a trapezoid. Example 2 A circular shaped garden of radius 15m contains a square concrete region of side length 4m.

The area of the composite figure is,

⇒ 22 m²

What is mean by Triangle?

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

We have to given that;

The Composite figure is made up of a Triangle, and a trapezoid.

Now,

Area of triangle is;

⇒ A = 1/2 × 3 × 4

⇒ A = 6 m²

And, Area of trapezoid is,

⇒ A = (a + b) × h/2

⇒ A = (10 + 6) × 2/2

⇒ A = 16 m²

Thus, The area of the composite figure is,

⇒ 6 + 16

⇒ 22 m²
