3. a company with loud machinery needs to cut its sound intensity to 44% of its original level. by how many decibels would the loudness be reduced? use the formula l=10log i/i(o). round to the nearest hundredth. a) 3.57 decibels *answer* b) 1.58 decibels c) 2.52 decibels d) 1.93 decibels 6. write the expression as a single natural logarithm. 2 in x-5 in c a. in(x2+c5) b. in x2/c5 *answer* c. in(x2-c5) d. inx2c5

  3.   The correct option is:  A) 3.57 decibels.

6.   The correct option is:  B)

Step-by-step explanation:

3.    Sound intensity is cut to 44% of its original level. That means, if the original sound intensity was 100, then now sound intensity will be 44.

So,   and

Using the formula , we will get.....

(Rounded to the nearest hundredth)

So, the loudness would be reduced by 3.57 decibels.

6.    Given expression is:    

First applying the property , we will get.....

Now using the formula, , we will get....

Thus, the answer as a single natural logarithm is  

all it means is function 3
