Paragraph 1 is the answer
I think there should be rules, because many people bully others online. so it's very important if there were rules. some messages online can sometimes be very disturbing. could you give me brainliest? its totally okay if not!
Chapter 22
In January 1989 the last of the Soviets leave the city and everyone watches them go. Laila is standing with her family when Tariq shows up in a huge Russian fur hat. Laila tells him he looks ridiculous. Laila is glad he can feel a little happiness, because ever since his uncle died the fall before and his father had a heart attack, he has been morose. Hasina, Tariq, and Laila eat together in the city that day. When Laila and Tariq go home with Babi and Mammy, a man on the bus says that the new leader, Mohammad Najibullah (1947–96), is a puppet president, not a real Muslim leader. Mammy prays on the bus. That night, Laila and Tariq go to see a movie. It is a Soviet film badly dubbed in Farsi, and they laugh at the stiff sentences that have nothing to do with what is really happening. The woman in the film, named Alyona, is in a love scene, kissing a man, and Tariq says he never wants to get married. Laila thinks about kissing Tariq and what it would be like. Tariq makes a snot joke to relieve the tension, but it is clear that he and Laila are a little uncomfortable after having watched a love scene together.
Chapter 23
In April 1992 Tariq's father, having had three strokes, is weak and unhealthy. Hasina has been married off to the man she feared her parents would force on her, and they have headed for Germany. The Soviet Union is falling apart, and the country of Russia emerges. Najibullah, who had been the puppet president in Afghanistan, claims to be an observant Muslim, but it is too little, too late. He ends up surrendering, and the Mujahideen finally come to Kabul. Mammy knows all of their names and all of the factions they run, but her hero is always Massoud. Mammy finally gets out of bed, opens her curtains, and goes back to her kitchen, rearranging it back to the way she likes it. She decides she will have a party and invites everyone she knows.
The mathematical concepts that Leonhard Euler's legacy included are as follows:
The formalization of function notation
The notation for the imaginary unit
The notation for the base of the natural logarithm
Remember, that all of Euler's legacy included the introduction of the concept of functions as well as the proper way to write them within a mathematical formula by using the notation f(x). Before his formalization of the notation, functional relationships were referred to by just one letter, F, or with Greek letters omitting the parentheses, φx. In fact, Euler spelled out much of the mathematical notation we use today, including the letter "e" for the base of the natural logarithm (also known as Euler's number), the letter "I" to denote the imaginary unit, and the Greek letter "Σ" for summations. He also encouraged the use of the Greek letter "π" to signify the ratio of a circle's circumference to its diameter.
