An educator wants to determine whether early exposure to school will affect IQ. He enlists the aid of the parents of 12 pairs of

preschool-age identical twins who agree to let their twins participate in this experiment. One member of each twin pair is enrolled in preschool for 2 years while the other member of each pair remains at home. At the end of the 2 years, the IQs of all the children are measured. The results follow.

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.

Tj owes $13.80 for text messaging in the month of March. If his text messaging complain cost $9 for the first 550 text messages
Gelneren [198K]

Answer: he sent 574 text messages that month

Step-by-step explanation:

Let x represent the number additional text messages that he sent that month.

If his text messaging complain cost $9 for the first 550 text messages and .20 for additional text messages, it means that the total cost of sending x text messages for a month would be

9 + 0.2(x - 550)

If Tj owes $13.80 for text messaging in the month of March, it means that

9 + 0.2(x - 550) = 13.8

0.2x - 110 = 13.8 - 9

0.2x = 13.8 - 9 + 110

0.2x = 114.8

x = 118.8/0.2

x = 574
