Question

word problem involving logarithms.
I will type it as an equation, please help!

Answer 1

The level of sound V in decibels with an intensity I can be modeled by

Answer 2

\[V=10 \log (I/10^(-16))\]

Answer 3

where I is intensity in watts per centimeter. Loud music can have an intensity of 10^(-5) watts per centimeter. Find the level of sound of loud music.

Answer 4

\[V=10\log \frac{10^{-5}}{10^{-16}}\]

Answer 5

So far i have
V=10 log (10^(-5)/10^(-16))

Answer 6

is that the answer?

Answer 7

\[=10\log 10^{11}\]

Answer 8

\[=10 \times 11 =110\]

Answer 9

Thanks! :)

Answer 10
