Creative Writing: Blog Post

From the book Internment by samira Ahmed.

Directions: Layla’s blog posts go viral and encourage others to keep fighting for the internees’ freedom. Pretend you’re an internee alongside Layla. Write your own blog post meant to inspire and inform the outside world. What details from the camp would you include? (Remember, this post is from YOUR point-of-view. How do you feel? What have you seen? Pretend you’re at Camp Mobius.)

Using what you have learned about script theory, dating and relationships. Plan 2 dates. 1 Level one date which would be a first date, and one level 2 date that wound help you filter out a potential unsuitable mate.

Script theory, whether practiced or not, suggests that intention and mindfulness in dating interactions will help to ensure individuals get what they need out of dating experiences, reducing time spent with people who are not a good match for themselves.

Level 1 Date | Plan | Rationale

Where would you go? What would you do?

How much time would you expect to spend?

How much money would you budget?

Three questions you would ask?

1. 2. 3.

A consumer is making saving plans for this year and the next. She knows her real income after taxes will be €20,000 in both years. Any part of her income saved this year will earn a real interest rate of 3% between this year and next year. Currently, the consumer has no wealth (no money in the bank or other financial assets, and no debts). There is no uncertainty about the future.

The consumer wants to save an amount this year that will allow her to

(1) make college tuition payments next year equal to €5000 in real terms; 
(2) enjoy exactly the same amount of consumption this year and next year, not counting tuition payments as part of next year’s consumption; and

(3) have neither assets nor debts at the end of next year.

a. How much should the consumer save this year? 
    How much should she consume?

1. Write a summary of the Political Cartoons on the Coronavirus including the identification of any issues, humor, or symbols that are used to convey the opinion of the artist and/or author. What current issue are these cartoons targeting in their message? What global effect does this issue present? Do you agree or disagree with the message?

Solve the equations

. 

1. Think of someone you know, a family member or a friend. 

2. If you were this person's personal trainer, would you have them work on their muscular strength or their muscular endurance? Why? Tell me why you made that choice for this person. 

3. Based on the information you know about this person (it could be alot or it could be a little), give me 5 exercises you think would help them. How many reps and sets will this person do for each exercise? 

4. Tell me why you chose the exercises you did for this family member or friend. 

5. What days will this person do their workout? rest?

4. Calculate the mass of ACTIVE INGREDIENT per tablet based on your moles of H+ neutralized per tablet. Compare with the information given on the label. (Formula of ACTIVE INGREDIENT: ___________ ) Answer: ___

A Tums® tablet is added into an Erlenmeyer flask. 25.00 mL of1.477 M of was added into a flask as an excessive reagent toneutralize the antacid tablet. Then, 1.507 M NaOH were used tocompletely neutralize the remaining HCl. The initial reading on theNaOH buret was 0.02 mL, the final reading was 17.79 mL. Calculatethe following:

a. Moles of HCl added into the flask

b. Volume of NaOH (in mL)

c. Moles of NaOH used to neutralize the remaining HCl

d. Moles of HCl neutralized by NaOH

e. Moles of HCl neutralized by a Tums® tablet

A 50.0-mL sample of a 1.50 M NaOH solution is titrated with a 2.71M HCl solution. What will be the final volume of solution when theNaOH has been completely neutralized by the HCl?

Direction: Read the text and analyze the claim and the supporting evidence presented. Then, judge the validity of the evidence.

The Digital Divide

By: Kim Czaccei Dacanay

The digital divide exists in the Philippine education system for the longest time, but the Pandemic exposed just how bad it is. The digital divide is the barrier between those who have access to computers and the internet and those who don't.   Educational attainment is heavily affected by the digital divide, and this remains true to many countries in the world. Many provinces in the Philippines have a slim to none access to the internet connection. Students and teachers would have to climb high places to get internet access. Also, as reported by STAR last year, 13 million Filipino households don't have electricity.   Therefore, the transition to online classes will put certain Filipino student population at a stark disadvantage. If there's no internet

READ AND UNDERSTAND Point of Diminishing Returns If a company decides to increase spending on advertising, it expects sales to increase. At first, sales will increase at an increasing rate and then increase at decreasing rate. The dollar amount 𝑥 at which the rate of change of sales goes from increasing to decreasing is called the point of diminishing returns. This is also the amount at which the rate of change has a maximum value. Money spent beyond this amount may increase sales but at a lower rate. A T-shirt manufacturer is planning to expand its workforce. It estimates that the number of T-shirts produced by hiring 𝑥new workers is given by  

(A) When is the rate of change of T-shirt production increasing and when is it decreasing?

(B) What is the point of diminishing returns and the maximum rate of change of T-shirt production?

(C) Write a brief interpretation of this result using the read and understand part.
