Consider a circle whose size can vary. Let r represent the radius of the circle (in cm) and let C represent the circumference of

the circle (in cm). Suppose the function g determines the radius of the circle in cm, r , given its circumference in cm, C . Write a function formula for g . g ( C ) = What does g ( 15 ) represent in this context? Select all that apply. The circumference (in cm) of a circle whose radius is 15 cm. The radius (in cm) of a circle whose circumference is 15 cm. A circle with a circumference of 15 cm. A circle with a radius of 15 cm. If g ( a ) = 15 , what does a represent in this context? Select all that apply. The circumference (in cm) of a circle whose radius is 15 cm. A circle with a circumference of 15 cm. A circle with a radius of 15 cm. The radius (in cm) of a circle whose circumference is 15 cm.

Answer:

g (15) represents the radius (in cm) of a circle whose circumference is 15 cm

if g (a) = 15, then a represents the circumference (in cm) of a circle whose radius is 15cm

Step-by-step explanation:

In a circle the following relationship can be posed:

C = 2 \pi r

Let g be a function that determines the radius of the circle from the value of its circumference, so, you have:

g (C) =\frac{C}{2\pi}

Thus, g (15) represents the radius (in cm) of a circle whose circumference is 15 cm. You have to g (15) =\frac{15}{2\pi}.

On the other hand, if g (a) = 15, then a represents the circumference (in cm) of a circle whose radius is 15cm. You have to a=2 \pi(15) = 30 \pi

Answer:

  a.

Step-by-step explanation:

For an even-index radical, ...

  \sqrt[n]{x^n}=|x|\qquad\text{n even}

This lets us simplify the given expression as follows:

  \sqrt[4]{81x^6y^4}-|y|\sqrt[4]{x^6}-\sqrt[4]{16x^2}=\sqrt[4]{(3xy)^4x^2}-|y|\sqrt[4]{x^4x^2}-\sqrt[4]{2^4x^2}\\\\=3|xy|\sqrt[4]{x^2}-|xy|\sqrt[4]{x^2}-2\sqrt[4]{x^2}=\boxed{2|xy|\sqrt[4]{x^2}-2\sqrt[4]{x^2}}
