The loudness, L, measured in decibels (Db), of a sound intensity, I, measured in watts per square meter, is defined as L = 10 lo
slamgirl [31]

Answer:

db_1 = 10 log_{10} (\frac{10^{-9}}{10^{-12}})= 30 db

And using the same formula we can find the number of decible for the Braylee's music:

db_2 = 10 log_{10} (\frac{10^{-3}}{10^{-12}})= 90 db

And since we want to find how many times louder is Braylee’s music than Jessica’s we can find the following relationship:

\frac{db_2}{db_1} = \frac{90 dB}{30 dB}= 3

So then we can conclude that the Braylee's music is 3 times louder then the Jessica's sound. And the best option would be:

3 times louder

Step-by-step explanation:

For this case we know that the loudness measured in decibels is given by this formula:

dB = 10 log_{10} (\frac{I}{I_o})

Where I_o = 10^{-12} W/m^2. Using this formula we can find the decibels for the sound for Jessica:

db_1 = 10 log_{10} (\frac{10^{-9}}{10^{-12}})= 30 db

And using the same formula we can find the number of decible for the Braylee's music:

db_2 = 10 log_{10} (\frac{10^{-3}}{10^{-12}})= 90 db

And since we want to find how many times louder is Braylee’s music than Jessica’s we can find the following relationship:

\frac{db_2}{db_1} = \frac{90 dB}{30 dB}= 3

So then we can conclude that the Braylee's music is 3 times louder then the Jessica's sound. And the best option would be:

3 times louder

F(x) = 0.54<br> g(x) = f(x + k)<br> for k=-2
Anton [14]

Answer: The answer is g(x)=f(x+k), therefore it’s k=gx/f.

Step-by-step explanation: You’ll need to isolate the variable by dividing each side by the factors that don't contain the variable.

I need to know which points go wj ere please
g100num [7]
The equations give you information as to where to plot points.

For y = -x + 1, you know the slope is -1, and the line intersects the y-axis at (0, 1). The y-axis is the vertical line; to plot (0, 1), find 1 on the vertical line and mark it. Now, the slope is -1; that means the line will slope downwards. To plot more points, count 1 unit down from (0, 1) and 1 unit to the right. You should end up at (1, 0).Connect those and you have a line.

For y = -2x + 4, the slope is -2 (so it will also slope downwards), and the y-intercept is 4. Find (0, 4) and plot it. The -2 tells you to count 2 units down (instead of 1 like we did for the last equation) and 1 over. That is the second line.

I hope this helps.
