\(\overrightarrow{BA}=\left(1;1;2\right)\)
Pt AB có dạng: \(\left\{{}\begin{matrix}x=-2+t\\y=1+t\\z=1+2t\end{matrix}\right.\)
Pt mặt phẳng qua C và vuông góc AB có dạng:
\(1\left(x-5\right)+y+2z=0\)
\(\Leftrightarrow x+y+2z-5=0\)
Tọa độ H thỏa mãn:
\(\left(-2+t\right)+\left(1+t\right)+2\left(1+2t\right)-5=0\)
\(\Rightarrow t=\dfrac{2}{3}\Rightarrow H\left(-\dfrac{4}{3};\dfrac{5}{3};\dfrac{7}{3}\right)\)

Hello everyone, today I will talk about Mars, the 4th planet in our solar system. The name of Mars originally comes from the name of the Roman god of war and agriculture. It may not seem like these two things go together, but they do. Mars protected those who fought for their communities and stayed home to raise crops for food. Mars has two natural satellites, and their names are Phobos and Deimos. With a radius of 2,106 miles (3,390 kilometers), Mars is about half the size of Earth. The atmosphere of Mars is much thinner than Earth's. It contains more than 95% carbon dioxide and much less than 1% oxygen. Mar's temperatures are from -151°C to 20°C. Mars is colder than Earth. If you were to stand on the surface of Mars on the equator at noon, it would feel like spring at your feet and winter at your head. Mar's surface is rocky, with canyons, volcanoes, dry lake beds and craters all over it. It's called Red Planet because iron minerals in the Martian soil oxidize, or rust, causing the soil and atmosphere to look red. One day on Mars takes a little over 24 hours. Mars makes a complete orbit around the Sun in 687 days. Thanks for listening.

Quá trình thoát hơi nước từ lá cây giúp làm giảm nhiệt độ của bề mặt lá vào những ngày nắng nóng bằng cách tiêu tốn năng lượng nhiệt để chuyển đổi nước từ trạng thái lỏng thành hơi. Điều này giúp duy trì một môi trường lý tưởng cho quá trình sinh lý của cây diễn ra.

A = 20012002 - 20022003
A = 20012002 - (182 x 11)2003
2001 không chia hết cho 11 nên A không chia hết cho 11
