The loudness, L, measured in decibels (Db), of a sound intensity, I, measured in watts per square meter, is defined as L=10logl/

matrenka [14]

Answer:

The the loudness heard by the mower will be 4 times the loudness heard by the Brandon.

Step-by-step explanation:

The least intense sound a human ear can hear , $I^o=10^{-12} dB$

The sound intensity level that Brandon can hear ,I= $10^{-10} dB$

$L=10\log\frac{I}{I^0}=10\log\frac{10^{-10} dB}{10^{-12}dB}=20$

The sound intensity level of the mower that Ahmad ,I'= $10^{-4} dB$

$L'=10\log\frac{I'}{I^0}=10\log\frac{10^{-4} dB}{10^{-12}dB}=80$

So, the:

$\frac{L}{L'}=\frac{20}{80}=\frac{1}{4}$

$L'=4\times L$

The the loudness heard by the mower will be 4 times the loudness heard by the Brandon.

Plot the following points to create

myrzilka [38]

Answer:

(1, -5)

Step-by-step explanation:

From the information that is given (1, -5) seems to be the logical answer since we have (1, 5), (-1, 5), and (-1, -5). 1 has been negative twice, 5 has been positive twice so to make things right add a positive +1 and a negative -5

I hope this helps!
