Answer:
<h2>
The intensity in decibel is 320 decibel </h2>
Step-by-step explanation:
Given the intensity, or loudness, of a sound measured in decibels (dB), according to the equation
where;
I is the intensity of a given sound and
is the threshold of hearing intensity
To get I(dB) when ![I=10^{32} Io](https://tex.z-dn.net/?f=I%3D10%5E%7B32%7D%20Io)
We will substitute the value of I =
into the equation above to have;
![I (dB)= 10log(\frac{10^{32}Io }{Io} )\\I(dB)=10log10^{32}\\ I(dB)=32*10log10\\](https://tex.z-dn.net/?f=I%20%28dB%29%3D%2010log%28%5Cfrac%7B10%5E%7B32%7DIo%20%7D%7BIo%7D%20%29%5C%5CI%28dB%29%3D10log10%5E%7B32%7D%5C%5C%20I%28dB%29%3D32%2A10log10%5C%5C)
Since log10 = 1;
![I(dB)=32*10(1)\\I(dB)=320](https://tex.z-dn.net/?f=I%28dB%29%3D32%2A10%281%29%5C%5CI%28dB%29%3D320)
The intensity in decibel is 320 decibel
Answer:
B. 9.6 %.
Step-by-step explanation:
A = P e^rt
His investment doubles so it comes to 3000 * 2 = $6000.
Substituting in the formula>
6000 = 3000e^7.2r ehere r is the interest rate.
e^7.2r = 2
Taking logs
7.2r = ln 2
r = ln2 / 7.2
r = 0.096
So the rate is 9.6%.
Answer:
A
Step-by-step explanation:
That is because the surface area requires us to add all the areas of each side together. Therefore, you must take (5*3)+(5*3)+(13*5)+(13*5)+(13*3)+(13*3) = 238.
Answer:x=3,-2
Step-by-step explanation:
x^2-x-6=0
x^2+2x-3x-6=0
x(x+2)-3(x+2)=0
(x+2)(x-3)=0
x=-2
x=3
