Answer:
The decibel level of this second sound is 48.021 decibels.
Step-by-step explanation:
The acoustic intensity (), measured in decibels, is defined by the following formula:
(1)
Where:
- Reference sound intensity, measured in watts per square meter.
- Real sound intensity, measured in watts per square meter.
If we know that and , then the real sound intensity of the first sound is:
The real sound intensity of the second sound is four times greater, that is:
If we know that and , then the acoustic intensity of the second sound is:
The decibel level of this second sound is 48.021 decibels.
100÷3 = 3.33333 which means 3
I believe after adding the x values and the degree values you would get x=10
that's the answer okayyyyyy

Answer:
(6, 4)
Step-by-step explanation:
The midpoint is found as the average of the coordinates of the end points.
M = (A +B)/2
M = ((9, 1) +(3, 7))/2 = (9+3, 1+7)/2 = (12, 8)/2
M = (6, 4)
The midpoint of segment AB is (x, y) = (6, 4).
