Answer is D since one of the expressions isn't a polynomial
Answer:
OPTION D: 0
Step-by-step explanation:
Rational numbers are subset of real numbers. These are the numbers that can be represented by a ratio of two integers i.e., of the form
, where 'q' is non-zero. The numbers after the decimal forms a pattern. Since, 'q' can be equal to 1, we conclude all integers are rational numbers.
Irrational numbers are the numbers which cannot be represented as ratios. They can only be represented as an approximate value. The numbers after the decimal do not form a pattern.
Here, A is 11.761038... Clearly, the decimal is non-terminating and does not follow a pattern.
In Option B we have √20. √20 = √2 . √10. We know that √2 is an irrational number. So, √20 is also irrational.
In Option C, we have the famous
. The value of
is 3.14.... It is an irrational number. The approximate representation of
is
.
In Option D, we have 0. It is an integer. So, it is rational as well.
Answer:
16 cm
Step-by-step explanation:
4 cm represents 5 km. There is a total length of 20 km, so you do 20/5=4. Since you have to multiply 5 by 4 to get 20, you also multiply 4cm by 4, and you get 16, or the amount of cm that represents 20 km.
