Answer:

C = 6.28 in.

A = 3.14 in.^2

Step-by-step explanation:

C = (pi)d

C = 3.14 * 2 in.

C = 6.28 in.

A = (pi)r^2

r = d/2 = 2 in./2 = 1 in.

A = 3.14 * (1 in.^2)

A = 3.14 in.^2

Choose all equivalent expression(s).
ElenaW [278]

<u>Given</u>:

The given expression is a b^{-3 x}

We need to determine the equivalent expression.

<u>Equivalent expression:</u>

Let us determine the equivalent expression.

The equivalent expression can be determined by simplifying the given expression.

Hence, let us apply the exponent rule to simplify the given expression.

Thus, applying the exponent rule, a^{-b}=\frac{1}{a^{b}}, we get;

a(\frac{1}{b^{3x}})

Rewriting the expression, we get;

a(\frac{1^{3x}}{b^{3x}})

Simplifying, we get;

a\left(\frac{1}{b}\right)^{3 x}

Thus, the equivalent expression is a\left(\frac{1}{b}\right)^{3 x}

Hence, Option C is the correct answer.
