Answers to Chinese exercise book Lesson 9 Sleep tomorrow

You go buy an exercise book. There are answers

Sixth grade primary school Chinese volume I exercise book group 6 answers

The answer is urgent! I don't know the topic? There are questions? I'm a sophomore in junior high school. I've learned all the texts you've learned. I can solve your problems

A choice
1. All the poems collected in the book of songs can be sung with music. According to the different forms, contents and languages of music and poetry, the book of songs can be divided into three parts, namely (), which are used in three ways, namely ()
A Fu B Feng C than D Xing e Ya f song
2. What's wrong with the explanation of Caiwei's words and sentences in the book of songs
"Yiyi" is used to describe the soft willows swaying in the wind. It seems to be a farewell and a retention
"Today I come to think of it, it's raining and snowing" means that it's winter when I come back. "Snowing" means that it's raining and snowing heavily. It seems to indicate welcome and indifference
3. The analysis of Caiwei's poem in the book of songs is correct
A uses the technique of blending feelings and scenes to compare the different scenes on the way home and on the way out
B this poem is about the feelings of the soldiers guarding the border on their way home. Through the poem, we can imagine their hardship, their weariness of military life, and their yearning and nostalgia for a peaceful family life

I don't know how to do some questions in Chinese. I'd like to ask you: 1. All the poems collected in the book of songs can be sung with music. According to the different forms, contents and languages of music and poems, the book of songs is divided into three parts, namely (BEF). There are three ways of expression, namely (ACD)

It is known that the images of two linear functions y = 1 / 2 (x + a) - 1 and y = - 3 (x-1) + a intersect in the fourth quadrant, and the value range of a is obtained
Because I will go to school later

Find the intersection point
Then we use inequality
Quadrant 4, abscissa > 0, ordinate

1 / (2 * 4) + 1 (4 * 6) + 1 (6 * 8) +. + 1 (48 * 50) simple calculation

1/(2*4)+1\(4*6)+1\(6*8)+.+1\(48*50)=1/2×(1/2-1/4)+1/2×(1/4-1/6)+1/2×(1/6-1/8)+.+1/2×(1/48-1/50)=1/2×(1/2-1/4+1/4-1/6+1/6-1/8+.+1/48-1/50)=1/2×(1/2-1/50)=1/2×24/50=6/25

If the solution of the equation 2x + 5m = 17 about X is a positive integer, then M =,

I think m is also a positive integer
X = (17-5m) / 2 is a positive integer,
x>0
(17-5m)/2>0
m

If the two focal coordinates F1 (- 2,0) F2 (2,0) of the ellipse are known and pass P (5 / 2, - 3 / 2), then the standard equation of the ellipse is obtained

Let the standard equation of ellipse be x ^ 2 / A ^ 2 + y ^ 2 / b ^ 2 = 1,
|F1F2|=2c=4,
So C = 2,
|PF1|+|PF2|=2a=2√10,
So a = √ 10,
b^2=a^2-c^2=6,
So the standard equation of ellipse
It is x ^ 2 / 10 + y ^ 2 / 6 = 1

According to the first five terms of the following infinite numbers, write a general formula of the sequence of numbers. 1) 2,2,2,2 2）4,9,16,25,36,…

1）2,2,2,2,2,…
an=2
2）4,9,16,25,36,…
an=(n+1)^2

19 ° 43 ′ 26 ″ X5 = () 178 ° 35 ′ divided by 4-32 ° 47 ′ = () 176 ° 52 ′ divided by 3 = ()

What's 29.2 percent

First, turn 29.2% into a fraction, which is equivalent to 73% of 250
