How do the graphs of f(x)= |x| and g(x)= 3|x| relate?

gavmur [86]

Answer:

Option C

Step-by-step explanation:

Let f(x) be a function and b a positive real numer, then:

$y = bf(x)$ represents a compression on a factor b of the function f(x).

In this case we have the function:

$f(x) = |x|$

If we do :

$y = 3f(x)$ we have:

$y = 3|x|$

And the original function f(x) is compressed by a factor of 3. Observe the attached image

Then, the answer is the correct option is option C

The length of a rectangle is 6 less than twice the width. If the perimeter is 60 inches, find the length and width.

pishuonlain [190]

Answer:

w = 12

l = 18

Step-by-step explanation:

Hello!

Recall the perimeter of a rectangle is <u>twice the sum of the length and the width of the rectangle.</u>

$P = 2(l + w)$

Let w be the width. The length is 6 less than twice the width. That means, l is 2w - 6.

Plug it into the formula and solve, given that P is 60.

<h3>Solve for w</h3>

$P = 2(l + w)$
$60 = 2(2w - 6 + w)$
$60 = 2(3w - 6)$
$60 = 6w - 12$
$72 = 6w$
$w = 12$

The width is 12 inches. We can plug in 12 for 2w - 6 to find the length.

<h3>Solve for l</h3>

$l = 2w - 6$
$l = 2(12) - 6$
$l = 24 - 6$
$l = 18$

The length is 18 inches.

The width is 12 inches, and the length is 18 inches.

A company has 25 employees. One day, 8 letters that did not have names on the envelopes arrived for 8 different employees. The m

Allisa [31]

1. The missing question here is : "what is the probability that the mail sorter placed each letter correctly"?

2. Name the letters L1, L2, ....L8 (Letter 1, Letter 2.... Letter 8)

3. The first letter has a probability of 1/25 to be placed in the correct mailbox.

Each of the remaining 7 letters have 1/25 probability, and these probabilities are related.

4. So the probability that each letter goes to the proper mailbox is $\frac{1}{25}* \frac{1}{25}* \frac{1}{25}* \frac{1}{25}* \frac{1}{25}* \frac{1}{25}* \frac{1}{25}* \frac{1}{25}= \frac{1}{ 25^{8}}$
