So in the problem where as shows a diagram of a circle having the value of m is 60 degree, so the ask is to calculate the mBDC and the best answer among the following choices is letter C. 30. I hope you are satisfied with my answer and feel free to ask for more
Step-by-step explanation: 8x+2y=0 move variabe to the right
next divide both sides by 2 and that gives you 2y =-8x to get the answer that is y= -4x
Sound intensity corresponding to 80 dB:
Step-by-step explanation:
The decibel of a normal conversation is 60 dB, which corresponds to an intensity of . (1)
The formula to use that relates the intensity of the sound in to the sound level in decibel is
Where
is the sound level in decibel
is the intensity
We can found by plugging in the numbers of (1):
Which corresponds to a sound level of 0 decibel.
Now we can find the intensity that corresponds to a sound level of
And from the equation we find:
