Answer:
A and D are not polynomials. B and C are polynomials
Step-by-step explanation:
In order to find out what function is a polynomial, you have to understand what a polynomial is. A polynomial is a sum of monomials that make up a polynomial expression. A mononomial is a real number, with a variable, and a exponent of a variable that makes up one term. For example 
is a monomial. It has a real number, a variable, and a exponent that makes up one term. A polynomial has one or more monomial terms that make it a polynomial. So firstly, a polynomial by definition cannot have a negative exponent. That eliminates D. Why? because by definition, the standard form of a polynomial function states that n cannot be positive, it has to be a nonnegative integer. Also, polynomials can only be real numbers. It cannot have a nonreal number. Radical forms without a perfect square are nonreal numbers. So that eliminates A. However, B and C can be polynomials because the definition of polynomials say that real numbers, nonnegative exponents, and constants can be part of a polynomial function. Even with the fraction, that would be part of rational expressions (polynomial/polynomial), which is polynomials. I hope this helps friend. Math can be tough to explain just as much as doing it :)
It’s A. 9 the equation is y=9x+0
Yes, they can. Rational numbers are also decimals (for example) so we can put an infinite amount of numbers between any 2 values, for example:
1,1
1,11
1,111
1,1111
2
5,328
5,3281
5,3282
50
90,01
90,011
etc.
Answer:
The appropriate answer is "0.0124".
Step-by-step explanation:
Given:
Test statistics,
z = 2.5
By using the z-table,
p value for one tailed test will be:
= 0.0062
For two-tailed test,
⇒ 
When
you construct parallel lines you have to copy an angle by creating
arcs with a compass. For inscribed polygons you also have to use a
compass in order to be sure that the figure is a regular polygon.
There for the when you are constructing inscribed polygons and
parallel lines, A compass is used to draw arcs.
Answer:
C) A compass is used to copy an angle.
