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:

I = 10⁻⁵ W/in² = 0.0155 W/m²
Therefore:

The sound intensity is about 101.9 dB
Answer:
Step-by-step explanation:
To answer this question, try to solve the system of equations. Start by plugging in "
" in for y in the second equation:

<em>*Combine like terms*</em>

<em>*Factor*</em>

<em>*Set each term equal to 0*</em>
x-1=0
<em>*Add 1 to both sides*</em>
x=1
C) There is exactly 1 solution.
