What is the irrational number in This set: 12.89, square root of 12 and 12/144 ?

kifflom [539]

Good night,

<span>Irrational numbers are those that can't be expressed as a fraction:

12.89 can be expressed as: </span> $\frac{1289}{100}$

$\frac{12}{144}= \frac{1}{12}$

<span>The above numbers can be expressed as a fraction, then the logical answer is: </span> $\sqrt{12}$

But we will check the answer:

$\sqrt{12}= \sqrt{2^{2}*3 } =2* \sqrt{3} =3.4641016...$

As you can see we can't express that number as a fraction, so that is te correct answer.

Which tables could be used to verify that the functions they represent are inverses of each other? Select two

devlian [24]

<h3>Answers: C and D</h3>

Why? Because they are mirrors of each other. In other words, one table has its x and y row swapped compared to the other table.

The input x = -120 leads to the output y = 627 in table C. Then in table D, we have the input x = 627 to go the output y = -120. Refer to the first column of each table mentioned. The same applies for the other columns as well. The inverse table undoes everything the original table does.
