What is the decibel level of a dog barking with intensity 10−5 watts per square inch? Use a logarithmic model to solve.

Vsevolod [243]

Answer:

The sound intensity is about 101.9 dB

Step-by-step explanation:

Sound intensity is the amount of sound energy per unit area.

The intensity of the dog bark is 10⁻⁵ W/in². The intensity of sound in decibels is given by:

$\beta=10\ dB*log(\frac{I}{I_o} )\\\\Where\ I=Sound\ intensity\ in \ W/m^2, I_o=reference\ sound\ intensity=10^{-12}\ W/m^2\, \beta= sound\ intensity\ in\ dB$

I = 10⁻⁵ W/in² = 0.0155 W/m²

Therefore:

$\beta=10\ dB*log(\frac{I}{I_o} )\\\\\beta=10\ dB*log(\frac{0.0155}{10^{-12}} )\\\\\beta=101.9\ dB$

The sound intensity is about 101.9 dB

Why is 9.6 rational <br> plz help quick...

dangina [55]

The reason that 9.6 is rational is because it can be turned into a fraction.

The fraction is 48/5.

Rational numbers are numbers that can be turned into a fraction, while irrational numbers a those who cannot be turned into a fraction.

Please helpppppp meeee

yKpoI14uk [10]

Answer:

0.25 Converges

Step-by-step explanation:

First, we need to expand our series so that we get the following:

$\sum _{n=1}^{\infty \:}\frac{n}{4^n}+\frac{1}{4^{n+1}}$

We can then use the series ratio test on each term. (L < 1 = absolutely convergent)

$\sum _{n=1}^{\infty \:}\frac{n}{4^n}$

$\lim_{n \to \infty} \frac{n}{4^{n}\\}$ =

⇒ converges

$\sum _{n=1}^{\infty \:}\frac{1}{4^n^+1}$

$\lim_{n \to \infty} \frac{n}{4^{n}^+1\\}$

⇒ converges

converges + converges

= converges

~Hope this helps! Once again, sorry if my explanation is a bit confusing~
