PLEASE HELPPP Today in Algebra class, Ethan learned about the expressions (1+ 1/x)^x and e, but he can't remember if (1+1/x)^x g

tester [92]

Part 1

Use your calculator to have it display $e \approx 2.71828182846$ and round that to five decimal places to get $e \approx 2.71828$

<h3>Answer: 2.71828</h3>

=============================================

Part 2

Plug in x = 5 to get

$y = \left(1 + \frac{1}{x}\right)^x\\\\y = \left(1 + \frac{1}{5}\right)^5\\\\y = 2.48832\\\\$

<h3>Answer: 2.48832</h3>

=============================================

Part 3

Now plug in x = 25

$y = \left(1 + \frac{1}{x}\right)^x\\\\y = \left(1 + \frac{1}{25}\right)^{25}\\\\y \approx 2.66583633148742\\\\y \approx 2.665 84\\\\$

<h3>Answer: 2.66584</h3>

=============================================

Part 4

Plug in x = 125

$y = \left(1 + \frac{1}{x}\right)^x\\\\y = \left(1 + \frac{1}{125}\right)^{125}\\\\y \approx 2.70748783321031\\\\y \approx 2.70749\\\\$

<h3>Answer: 2.70749</h3>

=============================================

Part 5

As x gets larger, it appears (1+1/x)^x is getting closer and closer to e = 2.71828 since the sequence of answers (from parts 2 through 4) was 2.48832, 2.66584, 2.70749.

The pressure exerted on the walls of a container by a gas enclosed within it is directly proportional to the temperature of the

Inessa [10]

Answer:

Step-by-step explanation:

If y is directly proportional to x, then the formula for that is a linear one:

y = kx, where k is the constant of proportionality. In our situation, if the pressure is directly proportional to the temp, then our formula is

P = kT. We need to find that value of k. Plug in what we have:

6 = k(440) so

k = .01363636 or as an equivalent fraction,

$k=\frac{3}{220}$

Now that have that value of k, we can use it in the formula again, this time with a different value for T to solve for P.

$P=(\frac{3}{220})380$ so

P = 5.181818 or as an equivalent fraction,

$P=\frac{513}{100}$

Round 23,879 to the nearest thousand

Vlad [161]

23, 879 to the nearest thousand.

The thousand digit is the 3, and we look at the digit after 3, which is 8, since 8 is more than 5, we round up the 3 to 4.

Therefore 23, 879 to the nearest thousand ≈ 24, 000

I hope this explains it.
