In Exercises 81 - 112, solve the logarithmic equation algebraically. Approximate the result to three decimal places. \( 2.1 = \ln 6x \)
In Exercises 121 - 128, solve the equation algebraically. Round the result to three decimal places. Verify your answer using a graphing utility. \( 2x \ln \left(\dfrac{1}{x}\right) - x = 0 \)
In Exercises 69 - 74, use the acidity model given by \( pH = -\log \left[H^+\right] \), where acidity \( (pH) \) is a measure of the hydrogen ion concentration \( \left[H^+\right] \) (measured in moles of hydrogen per liter) of a solution. find the \( pH \) if \( \left[H^+\right] = 1.13 \times 10^{-5} \).
The demand equation for a limited edition coin set is \( p = 1000\left(1 - \dfrac{5}{5 + e^{-0.001x}}\right) \). Find the demand \( x \) for a price of (a) \( p = \$139.50 \) and (b) \( p = \$99.99 \).
In Exercises 81 - 112, solve the logarithmic equation algebraically. Approximate the result to three decimal places. \( \log_2 x + \log_2 \left(x + 2\right) = \log_2\left(x + 6\right) \)
