My favorite place to shop is the countryside market near my house. Whenever I have free time on weekends, I often go to the market by bicycle with my mother. Although the countryside market is not as large as a supermarket, it gives me a feeling of closeness and familiarity. Each stall sells a variety of products, from fresh food to exquisite handicrafts. I love walking around the market, looking at the lush green vegetables, fresh fish, and chatting with the kind sellers. Going to the market is not only for shopping but also an opportunity for me to learn about the culture and life of local people. Those are interesting experiences that I cannot find anywhere else.

More than two hundred years ago, the term “environmental pollution” was quite strange to people. They lived healthy, drank pure water, and breathed fresh air. Nowadays, the situation is quite different. People all over the world are worried about things that are happening to the environment. Actually it is man that is destroying the surroundings with many kinds of wastes. Everybody knows that motorbikes and cars emit dangerous gases that cause poisonous air and cancer, but no one wants to travel on foot or by bicycle. Manufacturers know that wastes from factories make water and soil polluted, but they do not want to spend a lot of their money on treating the wastes safely. Scattering rubbish is bad for our health, but no one wants to spend time burying it. Is it worth talking a lot about pollution?

a. Theo định lý về đường phân giác trong tam giác, ta có:
$\frac{AB}{AC} = \frac{BD}{DC} \tag{1}$
Vì DE vuông góc với AB tại E, nên theo định lý Pythagoras, ta có:
$AE^2 = AB^2 - BE^2 \tag{2}$
$DE^2 = DB^2 - BE^2 \tag{3}$
Từ (2) và (3), ta có:
$AE^2 = DE^2 \Rightarrow AE = DE \tag{4}$
Từ (1) và (4), ta có:
$\frac{AB}{AC} = \frac{DE}{DC} = \frac{AE}{DC} \Rightarrow AC.BE = AB.EA$
b. Do AF // BC và AD cắt BC tại D, AF cắt AD tại K nên ta có:
$\frac{FA}{FK} = \frac{DA}{DK} \tag{5}$
Do DI // AB và DC cắt AB tại B, DI cắt DC tại K nên ta có:
$\frac{KI}{KD} = \frac{BI}{BD} \tag{6}$
Từ (5) và (6), ta có:
$\frac{FA}{FK} + \frac{KI}{KD} = \frac{DA}{DK} + \frac{BI}{BD} = 1$

              Giải:

a; Thiết lập hàm số y theo \(x\)

    y = 20000\(x\) 

b; Số tiền bạn Nam cần tiết kiệm là:

  2 000 000 - 800 000 = 1 200 000 (đồng)

 Thời gian bạn Nam có thể mua xe đạp kể từ khi bắt đầu tiết kiệm là:

 1 200 000 : 20 000 = 60 (ngày)

Kết luận:...

--> Khi nhiệt độ tăng, lượng khí thải nhà kính như CO2, CH4, N2O từ các hoạt động của con người sẽ tăng lên, dẫn đến tăng tốc độ biến đổi khí hậu.
--> Biến đổi lượng mưa và các hiện tượng thời tiết cực đoan như hạn hán, lũ lụt, bão, tuyết rơi dày đặc,... ảnh hưởng đến hệ sinh thái, nguồn nước, sản xuất nông nghiệp, và đời sống con người.
--> Khi nhiệt độ tăng, mực nước biển sẽ dâng cao do sự tan chảy của các chỏm băng ở hai cực, ảnh hưởng đến các khu vực ven biển.
