Perpendicular = opposite sign and reciprocal slope
-4 slope turns into 1/4
Y = 1/4x + b
11 = 1/4(-16) + b
11 = -4 + b, b = 15
Solution: y = 1/4x + 15
For this case we have the following equation:

Where,
I: <span>the intensity of a given sound
I0: </span><span> the threshold of a hearing intensity
</span>Substituting values in the given equation we have:
<span />

<span />Rewriting the equation we have:
<span />

<span />Then, by properties of logarithm we have:
<span />

<span />Finally we have:
<span />

Answer:
T<span />

D.80
Answer: A
Step by step: None
Answer: It is .571
Step-by-step explanation:
29 because 9*3 is 27 +2 equals 29
