Answer:

The following expressions are polynomials:

3x^2-5x^4+2x-12

x^5-5x^4+4x^3-3x^2+2x-1

x^3-7x^2+9x-5x^4-20

The following expressions are not polynomials:

\frac{4}{x^4}+\frac{3}{x^3}-\frac{2}{x^2}-1

x^{-5}-5x^{-4}+4x^{-3}-3x^{-2}+2x^{-1}-1

\sqrt[4]{x}-\sqrt[3]{x}+4\sqrt{x}-8x+16

Step-by-step explanation:

We are required to differentiate the expressions as polynomials and non-polynomials.

Since, we know,

A polynomial is an expression that involves variables and their coefficients separated by mathematical operations with the variables having non-negative integer values.

i.e. A polynomial is of the form, a_{n}x^{n}+a_{n-1}x^{n-1}+.....+a_{1}x+a_{0}, with 'n' being non-negative integer.

Thus, according to the definition, we have that,

The following expressions are polynomials:

3x^2-5x^4+2x-12

x^5-5x^4+4x^3-3x^2+2x-1

x^3-7x^2+9x-5x^4-20

The following expressions are not polynomials:

\frac{4}{x^4}+\frac{3}{x^3}-\frac{2}{x^2}-1

x^{-5}-5x^{-4}+4x^{-3}-3x^{-2}+2x^{-1}-1

\sqrt[4]{x}-\sqrt[3]{x}+4\sqrt{x}-8x+16

Henry knows that the circumference of a circle is 56.52 inches. What is the area of the circle? (Use 3.14 for  and round to the
ahrayia [7]

The area of circle is 254.34 square inches, if the  circumference of a circle is 56.52 inches.

Step-by-step explanation:

The given is,

                       Circumference of a circle is 56.52 inches.

                       \pi =3.14

Step:1

             Formula for circumference of circle is,

                                   Circumference, C = 2\pi r........................(1)

              Where, r - Radius of circle

              From the given,

                           C = 56.52 inches

              Equation (1) becomes,

                                          56.52 = 2 \pi (r)

                                          56.52 = (2) (3.14) (r)

                                          56.52 = 6.28 (r)

                                                 r = \frac{56.52}{6.28}

                                                  r = 9 inches

Step:2

             Formula for area of circle,

                                       Area,A = \pi r^{2}............................(2)

             Where, r  - Radius of circle

             From the given,

                               r = 9 inches

             Equation (2) becomes,

                               A = \pi  (9)^{2}

                                   = (3.14) (81)

                                   = 254.34

      Area of circle, A = 254.34 square inches

Result:

          The area of circle is 254.34 square inches, if the  circumference of a circle is 56.52 inches.
