The doormen consulted with each other and said, "This pot of wine is not enough for everyone to drink, and there will be a surplus for one person to drink."

He picked up the flask and was about to drink it, but he triumphantly held the flask in his left hand, and continued to draw the snake with his right hand, and said:

I could add a few more legs to it! But before he could finish drawing his feet, another man had already drawn the serpent. The man snatched the jug of wine and said:

After crossing the river, Xiang Yu ordered the whole army: "All the ships are sunk, the cauldron is broken, the house is burned, and the food is held for three days, so as to show that the soldiers will die, and none of them will return their hearts."

Question 5: 1 -1 3 -3

Question 6: 2007 2008 is 2007/2008

5, i.e. 100 3 = 33....1

That is, the 34th item is 1, and the 35th item is less than 0

So n takes 34

At this time, sum: (100+1)x34 2=1717 .

6. The minimum is: 25, the maximum: 385

Sum: (25+385)x21 2 = 4305

Let 1+ Qi Lizhi (1+x)=t

1+x=(t-1)²

x=t²-2t

dx=(2t-2)dt

Original = high elimination (2t-2) dt t

2dt - 2dt/t

2t-2ln|t|+c

2[1+ (1+x)]-2ln[1+ (1+x)]+c let x=sint

dx=costdt

1-x²=cos²t

Original. ∫costdt/cos³t

sec²tdt

tant+c

sint=x,cos t=1-x,cost= (1-x)primitive=[x(1-x)]c

Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, is the first day of the week. Saturday Saturday is the last weekend. The concept needs to be clear.

15.Suppose the incubation period of ducks is x, and the incubation period of geese is y. The equiquant relationship is as follows:

21=x*(3/4)

x=y*(14/15)

So x=28, y=30

16.Set the fawn to drink x liters of water a day.

2=x*(2 5), so x=2 (2 5)=5 liters.

5(1) mg,ag,Fe+CuSO4===Cu+FeSO4,displacement reaction.

2) a, cuo, becomes turbid, greater than.

6（1）200×97%×112/(112+24)=2）100×80%×（168/200）/96%=70t
