Question
![### Computation of Sound Intensity in Decibels
Sound waves, measured in decibels (dB), can be computed using the formula:
\[ f(x) = 10 \log I + 120 \]
where \(I\) is the intensity of the sound measured in watts per square meter.
For instance, if a jet airplane has a sound intensity of 2 watts per square meter, the formula helps determine the decibel reading.
#### Problem Example:
If a jet airplane has a sound intensity of 2 watts per square meter, find the decibel reading in dB. Round your answer to two decimal places.
