Apply the distributive property:
12(4-v)
(12*4)-(v*12)
48-12v

48-12v. you multiply both of the things inside of the parenthesis.

3. A company with loud machinery needs to cut its sound intensity to 44% of its original level. By how many decibels would the l

sergeinik [125]

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

6. The correct option is: B) $ln(\frac{x^2}{c^5})$ 

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, $I_{0}= 100$ and $I= 44$

Using the formula $L= 10log(\frac{I}{I_{0}})$ , we will get.....

$L= 10log(\frac{44}{100})\\ \\ L= 10log(0.44)\\ \\ L= 10(-0.3565...)=-3.565...\approx -3.57$

(Rounded to the nearest hundredth)

So, the loudness would be reduced by 3.57 decibels.

6. Given expression is: $2ln(x) - 5ln(c)$

First applying the property $m*log(x)= log(x^m)$ , we will get.....

$ln(x^2)-ln(c^5)$

Now using the formula, $log(a)-log(b)= log(\frac{a}{b})$ , we will get....

$ln(x^2)-ln(c^5) = ln(\frac{x^2}{c^5})$

Thus, the answer as a single natural logarithm is $ln(\frac{x^2}{c^5})$

9. Consider the function f(x) = x² + 3x – 4.

BaLLatris [955]

Answer:

c. f(x) = (x + 4)(x - 1)

Step-by-step explanation:

Since you're familiar with the product of two binomials:

(x +a)(x +b) = x² + (a+b)x + ab

you know that the constants in the binomial factors must ...

have a product of -4
have a sum of +3

All of the choices except B have binomial constants that have a product of -4.

In order, the sums of the remaining choices are ...

A: 1-4 = -3

C: 4-1 = 3 . . . . this is the correct choice

D: -2+2 = 0
