In the future, people will travel in many new and exciting ways thanks to advanced technology and a focus on protecting the environment. First, electric vehicles will become very popular because they are clean and reduce pollution. Many countries are building more charging stations to support these vehicles. Second, autonomous or self-driving cars and buses will be common, making travel safer and more efficient. These vehicles can drive themselves using artificial intelligence, which helps reduce accidents and traffic jams. Third, new transportation methods like high-speed trains, drones for delivery, and flying taxis may become normal, making travel faster and more convenient. Finally, smart transportation systems using 5G and digital technology will help people plan trips easily and reduce travel time. Overall, future travel will be greener, faster, safer, and more comfortable for everyone.

Người yêu của em như con tinh tinh

a: Số tiền phải trả cho 1km đầu tiên là:

\(1\cdot20000=20000\left(đồng\right)\)

Số tiền phải trả cho 24km từ 2 đến 25 là:

\(24\cdot14000=336000\left(đồng\right)\)

Số tiền phải trả cho x-25 km còn lại là:

\(12000\left(x-25\right)\left(đồng\right)\)

Tổng số tiền phải trả là:

\(20000+336000+12000\left(x-25\right)\)

\(=356000+12000x-300000=12000x+56000\left(đồng\right)\)

b: Số tiền phải trả là:

\(12000\cdot28+56000=392000\left(đồng\right)\)

a: Xét ΔBAD vuông tại A và ΔBED vuông tại E có

BD chung

\(\widehat{ABD}=\widehat{EBD}\)

Do đó: ΔBAD=ΔBED

b: ΔBAD=ΔBED

=>DA=DE

mà DE<DC(ΔDEC vuông tại E)

nên DA<DC

c: Gọi M là giao điểm của CF và BA

Xét ΔCMB có

CA,BF là các đường cao

CA cắt BF tại D

Do đó: D là trực tâm của ΔCMB

=>MD\(\perp\)BC

mà DE\(\perp\)BC

và MD,DE có điểm chung là D

nên M,D,E thẳng hàng

=>CF,DE,BA đồng quy tại M
