Select all of the expressions that would be considered a polynomial

Option B:

Option D:

Solution:

Polynomial definition:

A polynomial can have constants, variables and exponents and fractional coefficient.

A polynomial cannot have fractional exponent, negative exponent and never division by a variable.

To select the expressions that would be considered as a polynomial.

Option A:

√x is not, because the exponent is ½. Fractional exponents are not polynomials.

This is not a polynomial.

Option B:

A polynomial can have constants, variables and exponents.

This is a polynomial.

Option C:

Fractional exponents are not polynomials.

This is not a polynomial.

Option D:

Fractional coefficients are allowed.

This is a polynomial.

Hence and are polynomial.

answer

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)

answer: yes, since the line has a steeper rate of change than the exponential the y-values will be greater and they will only intersect one time.
