What single decimal multiplier would you use to decrease by 12% followed by a 4% increase

Answer:

The single decimal multiplier is 0.9152

Step-by-step explanation:

Here, we want to write a single decimal number that would work as to decrease an original value by 12% and increase it also by 4%

Let the original value be x

12% = 12/100 = 0.12

So decreasing by 12% would be x-0.12x = 0.88x

Now this 0.88x, we shall increase it by 4%

4% is same as 0.04

Thus by increasing , we have;

0.88x + 0.04(0.88x)

= 0.88x + 0.0352x = 0.9152x

So the single factor we are multiplying by is 0.9152

What kind of sequence is the pattern 1, 6, 7, 13, 20, ...?
AlexFokin [52]

Answer:

The given sequence 6, 7, 13, 20, ... is a recursive sequence

Step-by-step explanation:

As the given sequence is

6, 7, 13, 20, ...

  • It cannot be an arithmetic sequence as the common difference between two consecutive terms in not constant.

As

d = 7-6=1,  d = 13-7=6

As d is not same. Hence, it cannot be an arithmetic sequence.

  • It also cannot be a geometrical sequence and exponential sequence.

It cannot be geometric sequence as the common ratio between two consecutive terms in not constant.

As

r = 7-6=1,  r = 13-7=6

r = \frac{7}{6},  r = \frac{13}{7}

As r is not same, Hence, it cannot be a geometric sequence or exponential sequence. As exponential sequence and geometric sequence are basically the same thing.

So, if we carefully observe, we can determine that:

  • The given sequence 6, 7, 13, 20, ... is a recursive sequence.

Please have a close look that each term is being created by adding the preceding two terms.

For example, the sequence is generated by starting from 1.

     {\displaystyle F_{1}=1

and

     {\displaystyle F_{n}=F_{n-1}+F_{n-2}}

for n > 1.

Prove the triangles are congruent
frozen [14]

Answer:

1: two sides and angle of one triangle are congruent.

Step-by-step explanation:

The triangles are congruent because two sides and the generated angle of a triangle correspond to their respective sections. If two angles and the side used in one triangle are identical.

Hope this helps
