Describe the image D first reflected across line I then across line m.
AleksAgata [21]

Answer:

Please check the <em>attached figure</em> to determine the new orientation of image D after first reflecting across line l and then across line m.

Step-by-step explanation:

<em>Describe the image D first reflected across line I then across line m.</em>

In mathematics, a reflection can be termed as just a "flipping" or an "overturn "of an object over a certain axis or line - commonly known as the line of reflection - without altering the shape and size of the original object, though facing in opposite directions.  

<em />

<em>First Step: </em>

After the first reflection of letter D across the line l, it would again be a letter D. But the letter D would be a "turned D" letter, though having the same size but locating itself to the right side of the line l as shown in figure. The letter "Turned D" will have its curved side facing the left.

Hence, after the first reflection of letter D across the line l, the "turned D" will have its curved side facing the left, would be having same size but locating to the right side of the line l and also having located to the left side of line m as shown in figure.

<em>Second Step: </em>

After the second reflection across the line m, it would again convert, flip or overturn the the letter to the original object or letter, and its curved side again facing the right (original shape) , but now it would be locating itself to the right side of the line m as shown in figure.

So, new orientation of the image D is attached below.

Identify a pattern and find the next three numbers in the pattern.<br> 3,6,10,15, . . .
slega [8]

The pattern exists described as a sequence of repeating objects, shapes, or numbers. Patterns can also occasionally be referred to as a series.

The pattern follows the rule = Σn+(n+1)

The next three numbers in the pattern be 3, 6, 10, 15, 21, 28, 36.

<h3>What is meant by pattern?</h3>

A recurring arrangement of numbers, forms, colors, and other elements constitutes a pattern in mathematics. The pattern can be connected to any kind of occasion or thing. When a group of numbers are arranged in a particular way, the arrangement is referred to as a pattern. Patterns can also occasionally be referred to as a series.

Let the numbers in the pattern be 3,6,10,15, . . .

t1 = 1 + 2 = 3

t2 = 3 + 3 = 6

t3 = 6 + 4 = 10

t4 = 10 + 5 = 15

t5 = 15 + 6 = 21

t6 = 21 + 7 = 28

t7 = 28 + 8 = 36

The pattern follows the rule = Σn+(n+1)

Therefore, the next three numbers is 21, 28, 36.
