Question

Find the arc length of y = 1/12(x+6)^3+(x+6)^-1 over [1,2]

**Problem Statement:**

Find the arc length of the function:

\[ y = \frac{1}{12}(x + 6)^3 + (x + 6)^{-1} \]

for the interval \( 1 \leq x \leq 2 \).

(Give your answer to three decimal places.)

**Solution:**

To calculate the arc length \( s \) of the curve, use the formula for arc length from calculus, which is:

\[ s = \int_{a}^{b} \sqrt{1 + \left(\frac{dy}{dx}\right)^2} \, dx \]

1. **Differentiate the function** \( y \) with respect to \( x \) to find \(\frac{dy}{dx}\).
2. **Substitute** \(\frac{dy}{dx}\) into the arc length formula.
3. **Evaluate** the integral from \( x = 1 \) to \( x = 2 \).
4. **Provide** the answer to three decimal places.
