The sound intensity of the Pile Driver is 39.5
or nearly 40 times the sound intensity of the jackhammer.
Given with Loudness in dB for pile driver = 112 dB
We have to convert it in terms of sound intensity.
First,
112dB/10 = 11.2
Then we'll use this as exponent of 10
(10)^(11.2) = 1.5849 * 10 ^ 11
Then use the equation of Watts per square meter to find the intensity:
I / (10^-12 W/m^2) =1.5849 * 10 ^ 11
I = sound intensity = 0.158
Then compare:
Sound intensity of Pile Driver/ Sound intensity of Jackhammer
(0.158) / (0.004)
= 39.5
or nearly 40 times the jackhammer.
-13 c I think. It is this way because if it went down 15, then you subtract 2-15. 2-2 = 0, and then 0-13= -13 c. Hope this helps
Answer:
Step-by-step explanation:
The following is the logarithm quotient rule:

Plugging in the values we have above gives us the following:



we have


![(fog)(x)=[\frac{1}{x-13}]+7](https://tex.z-dn.net/?f=%28fog%29%28x%29%3D%5B%5Cfrac%7B1%7D%7Bx-13%7D%5D%2B7)
we know that
the denominator cannot be zero, therefore the value of x cannot be 
The domain are all real numbers except the number 
therefore
<u>the answer is the option</u>
{x|≠13}
Answer:
$12.18
Step-by-step explanation:
Given:
Cost of 0.8 liter bottle of Mexican wine = 101 pesos
or
cost of 1 liter bottle of Mexican wine =
pesos
Now,
1 Mexican pesos = 0.051 dollars
thus,
cost of 1 liter bottle of Mexican wine =
dollars
also,
1 gallon = 3.78541 Liter
Thus,
half gallon =
= 1.892705 Liters
therefore,
cost of half gallon jug =
dollars
or
cost of half gallon jug of wine = $12.18
