Most wall stubs are 2 feet apart, so before you put on sheet rock you must measure, most sheets of sheet rock are 8 feet wide, some are 10, but people don't tend to use them because their so big and heavy.

I hope this helps.

Find the inverse of each function 1. f(x) = 4/(x+2) - 2 2. f(x)= -2x^5 - 3

lisabon 2012 [21]

We are given the following function:

f(x) = 4/(x+2) - 2

We are asked to determine the inverse of this function. To do that we will first change the "f(x)" for "y":

$y = \frac{4}{x + 2} - 2$

Now we will switch "x" and "y", like this:

$x = \frac{4}{x + 2} - 2$

Now we will solve for "y", first by adding 2 to both sides:

$x + 2 = \frac{4}{y + 2}$

Now we multiply both sides by "y+2":

$(y + 2)(x + 2) = 4$

Now we divide both sides by "x+2":

$y + 2 = \frac{4}{x + 2}$

Now we subtract 2 to both sides:

$y = \frac{4}{x + 2} - 2$

Now we change "y" for the inverse of f(x), that is:

${f}^{ - 1} (x) = \frac{4}{x + 2} - 2$

And thus we found the inverse. A similar procedure can be used for function 2.

Answer: 5 $y$ − 1 + $y^{2}$

Step-by-step explanation:

Hey there! I will give the following steps, if you have any questions feel free to ask me in the comments below. Thank you!

Step 1: Collect like terms.

(3 $y$ + 2 $y$ ) + (6 − 3 − 4) + (-6 $y^{2}$ + 7 $y^{2}$ )

Step 2: Simplify.

5 $y$ − 1 + $y^{2}$

The FBI wants to determine the effectiveness of their 10 Most Wanted list. To do so, they need to find out the fraction of peopl

Zinaida [17]

Answer:

Step-by-step explanation:

Hello!

The variable of interest is X: number of criminals in the 10 Most Wanted list that were captured in a sample of 523 suspected criminals.

The number of criminals that were captured is 172 out of 523.

To calculate the sample proportion, you have to divide the number of success, in this case, captured criminals, by the total number of criminals sampled:

^p= 172/523= 0.329

I hope this helps!
