How many faces, edges and vertices does the shape below have?<br> Faces: <br> Edges: <br> Vertices:
olga55 [171]

the number of faces, edges and vertices the shape below has is 4, 4 and 6 respectively.

<h3>How to determine the number</h3>

It is important to note that according to Euler’s formula for any convex polyhedron, the number of Faces (F) and vertices (V) added together is exactly two more than the number of edges (E).

It is mathematically written as;

Face + vertices = 2 + edges

F + V = 2 + E

From the figure given, we can see that it is a kite

Number of vertices = 4

Number of faces = 4

2 + edges = faces + vertices

2 + edges = 4 + 4

2 + edges = 8

Edges = 8 - 2

Edges = 6

Thus, the number of faces, edges and vertices the shape below has is 4, 4 and 6 respectively.

Decide whether each number is written in standard notation or scientific notation.
VARVARA [1.3K]

The answers are as follows:

3000- standard notation

4.2*10 raised to 4 - scientific notation

1.05 × 10 raised to power –7  - scientific notation

0.0013 - standard notation

6,500,000 - standard notation

6.2 × 10 raised to power 19 - scientific notation

Concept: Standard notation is a way of writing a number so it is easier to read. It is often used for very large or very small numbers.

Scientific notation is a way of writing very large or very small numbers. A number is written in scientific notation when a number between 1 and 10 is multiplied by a power of 10.

In the given questions,

3000- standard notation

4.2*10 raised to 4 - scientific notation

1.05 × 10 raised to power –7  - scientific notation

0.0013 - standard notation

6,500,000 - standard notation

6.2 × 10 raised to power 19 - scientific notation
