Which of the following are not Polynomials?
2 answers:
Answer:
hmmm....
I don't think any of them are ????
that is a exponent that is a fraction ......
it appears that all the answers have fractional exponents, negative exponents, or divide by a variable??
Step-by-step explanation:
Polynomials cannot contain division by a variable.
For example, 2y2+7x/4 is a polynomial because 4 is not a variable. However, 2y2+7x/(1+x) is not a polynomial as it contains division by a variable.
Polynomials cannot contain negative exponents.
You cannot have 2y-2+7x-4. Negative exponents are a form of division by a variable (to make the negative exponent positive, you have to divide.) For example, x-3 is the same thing as 1/x3.
Polynomials cannot contain fractional exponents.
Terms containing fractional exponents (such as 3x+2y1/2-1) are not considered polynomials.

, or instead of r, you can put D, which is r times 2
The diameteris 2.5, so, the answer would be
pi times 2.5, where pie = 3.14
So, the answer is 2.5 * 3.14 = 7.85 or 7.9
