a decibel is a logarithmic unit that can be used to measure the intensity of a sound. the function y = 10logx gives the intensity of a sound in decibels, where x is the ratio of the intensity of the sound to a reference intensity. the reference intensity is generally set at the threshold of hearing. use the graphing utility to graph the decibel function. the sound intensity of rustling leaves is 100 times the reference intensity. use your graph to determine the sound intensity of rustling leaves in decibels. 20 decibels complete a whisper has a sound intensity of 30 decibels. use your graph to help you complete the following statement. the sound intensity of a whisper is times the reference intensity. done

Answer

Explanation:

Step1: Use the given formula

We are given the formula $y = 10\log x$, where $y$ is the sound - intensity in decibels and $x$ is the ratio of the sound intensity to the reference intensity. We know $y = 30$. So, $30=10\log x$.

Step2: Solve for $\log x$

Divide both sides of the equation $30 = 10\log x$ by 10. We get $\frac{30}{10}=\log x$, so $\log x = 3$.

Step3: Convert from logarithmic to exponential form

Since $\log x$ is base - 10 logarithm, and $\log x = 3$, in exponential form $x = 10^{3}$ (because if $\log_{a}b=c$, then $b=a^{c}$, here $a = 10$, $c = 3$).
