Math Question

Question 4 of 10 A jackhammer has a decibel reading of 120 . Given the formula for a decibel reading, \( D=10 \log \frac{1}{6} \), where \( i_{0}=10^{-12} \) is the intensity of the sound threshold, choose the equation that finds 1 , the intensity measurement of the jackhammer in \( W / \mathrm{m}^{2} \). A. \( \log i=12+\log 0 \) B. \( \log i=\frac{12}{10^{-12}} \) C. \( \log i=12+\log 10^{-12} \) D. \( \log i=\frac{12}{\log i_{0}} \)
