Five thousand years of long journey, all the way wind and rain all the way. The Chinese nation once had the glory of opening to the world, strong national strength in Han and Tang Dynasties, and also had the humiliation of being closed to the outside world, backward and beaten in modern times. The road ahead is full of hardships, but the hardships contain hope. Now China is going to the world with more firm, more vigorous and more heroic steps. National rejuvenation is just around the corner; China is taking off, be a trend which cannot be halted.
Looking back at history, "the road is long, the road is far away" Zhang Qian was sent to the western regions, Xuanzang traveled to the west to learn Buddhist scriptures, Jianzhen traveled to the east to preach, and Zheng He made seven voyages to the West. Our ancestors once made China go to the world, let the world know China, and ushered in great development in the great opening-up. The four great inventions were once our pride. But in modern times, China's feudal rulers were arrogant, closed-minded, and rigid in thinking, The world has left China behind. The Opium War, the Sino French war, the Sino Russian war, the Treaty of Nanjing, the Treaty of Beijing, the Treaty of Shimonoseki, too many sufferings, too many shackles, the Oriental giant. What's the matter with you? The Oriental giant, why don't you roar? / / / the Chinese Communist Party leads the Chinese people to stand up, The history of humiliation is gone forever, and brilliant prospects are coming to us. "Resist US aggression and aid Korea, avenge our country, make friends at the Bandung Conference, Daqing oil plays a triumphant song, two bombs and one star show their skills." self reliance, internal strength; five principles, external friendship.

The bright five star red flag is finally solemnly raised in the United Nations
Looking forward to the future, the Chinese nation "seeks from top to bottom" The road is tortuous, but twists and turns will only make the Chinese people more rational. After ten years of civil strife, the Party led the Chinese people to reform and open up. Under the leadership of Deng Xiaoping, the chief designer, "the east wind of reform will send the winter away, The special economic zone, coastal pearl, the 863 plan, one country, two systems, the upsurge of studying abroad and the great wall of ice and snow all show China's boundless development vigor and vitality. "Riding the wind and breaking the waves sometimes, flying the clouds and sailing straight to the sea." adhering to the opening up, advancing with the times, creating a new chapter: the rise of Pudong, the return of Hong Kong and Macao; Beijing's successful bid for the Olympic Games, Shenzhou's space flight, Shanghai's APEC meeting and China's accession to the WTO indicate the rapid development and continuous strength of China's Dragon
History enlightens us: a nation that goes to the world must be self-respect and self-reliance, self-confidence and self-improvement; the future calls us: a nation that goes to the world must be broad-minded and learn from others' strong points, in order to stand tall among the nations in the world. Today we are the hope of our ancestors, and tomorrow we are the pillars of our motherland. Our motherland will always be in our heart, and our heart belongs to China

Simple calculation ^ o ^ y (^_ ^)(^_ ^)(^_ ^)(^_ ^)(^_ ^)

199 = 200-1, 150-0.75 = 149.25

Ln (x + 1) derivation

=1/(x+1)*(x+1)'
=1/(x+1)

46.3*0.56+5.38*5.6-0.056=?

46.3 * 0.56 + 53.8 * 0.56-0.56 * 0.1 = 0.56 * (46.3 + 53.8-0.1) = 56 understand?

There's a number where the number of molecules plus 2 equals 3 / 5, and the number of molecules minus 2 equals 1 / 3?
We need formulas. We don't need equations. We don't need this
7/15
3 / 5-1 / 3 = 4 / 15 2 * (2 / denominator), so the numerator of this fraction is 15
=Original fraction = 1 / 3 + (2 / denominator) = 1 / 3 + 2 / 15 = 7 / 15
Don't use this formula
But if you can help me explain what "2 * (2 / denominator) means, so the numerator of the fraction is 15"
Additional points if possible

The denominator has not changed
The numerator plus 2 accounts for 3 / 5 of the denominator
The numerator minus 2 accounts for 1 / 3 of the denominator
So the denominator is: (2 + 2) / (3 / 5-1 / 3) = 15
The original molecule is: 15 × 3 / 5-2 = 7
A: the score is 7 / 15

Given the quadratic function f (x) = x ^ 2-2x + 3, when x belongs to [T, t + 1], find the minimum value g (T) of F (x)

f(x)=x^2-2x+3=（x-1)^2+2
The function is minimum at 1, decreasing on the left and increasing on the right
When 1 is in [T, t + 1], that is 0

Simple calculation of 0.384 * 102-38.4

0.384*102-38.4
=0.384*102-0.384*100
=0.384*(102-100)
=0.384*2
=0.768
