The loudest sound, measured in decibels, is calculated using the formula L=10 log, where L is the loudness, and I is the intensi
12345 [234]

The intensity of a fire alarm that measures 125 dB loud is 268,337.29

<h3>Formula and expressions</h3>

Given the expression L=10 logI

where;

  • L is the loudness
  • I is the intensity of the sound.

Given the following parameters

L = 125dB

Substitute the given parameters into the following

L=10 logI

125 = 10logI

logI = 125/10

logI = 12.5

I = e^12.5

I = 268,337.29

Hence the intensity of a fire alarm that measures 125 dB loud is 268,337.29

1. The amount of extension in an elastic spring varies directly as the weight hung on it. If a weight of 150 gm produces an exte
gregori [183]

Answer:

900 g

Step-by-step explanation:

let e be extension and w be weight

given e varies directly as w then the equation relating them is

e = kw ← k is the constant of variation

to find k use the condition w = 150 , e = 2.9 , then

2.9 = 150k ( divide both sides by 150 )

\frac{2.9}{150} = k , that is

k = \frac{29}{1500}

e = \frac{29}{1500} w ← equation of variation

when e = 17.4 , then

17.4 = \frac{29}{1500} w ( multiply both sides by 1500 )

26100 = 29w ( divide both sides by 29 )

900 = w

What is the limit of cosine as x approaches infinity?
sesenic [268]
Does not exist, since the graph of cosine is continuous between the intervals [-1,1]. You do not know where it will be when it “reaches” infinity

What is the range of f(x) = 3X + 9?<br> {yly&lt;9}<br> {yly&gt;9}<br> {yly&gt; 3}<br> {yly&lt;3}
4vir4ik [10]

Answer:

the set of all real numbers

Step-by-step explanation:

f(x) = 3X + 9 is a polynomial, and so both the domain and the range are "the set of all real numbers."  

None of your answer choices match this.  Check with your teacher if you can.
