How does grass make sentences


Spring is coming, the grass is green
She planted a little grass
That grass is so green!
Why isn't it grass?



Tolerance is the field of big trees and grass, the sky of sunshine and rainstorm


Tolerance is to blow open the closed and conservative wind, to wash the narrow and selfish rain, to disperse the cold sunshine
Tolerance is the sea of crabs, clams, fish and shrimp, the fire of burning, blocking and isolating, and the sweet spring of washing filthy darkness



With grass like Like Like . make sentences


On the hillside after the rain, the grass grew buds like waking up, blossomed like a race, and climbed the whole cliff like hearing the call of assembly



Factorization x3-3x2-2
A higher inequality problem 5-x / x2-2x-3 is greater than or equal to X-1
I reduced it to x3-3x2-2 / x2-2x-3 less than or equal to 0
As long as the molecules above can be broken down, it can be done


It's better to solve the equation first
But it can be broken down into
(x+3.195823345)(x-0.0979117+0.785i)(x-0.0979117-0.785i)
If you want to break it down into algebraic expressions
It is suggested that you use cubic equation of one variable
Cardan formula
However, the solution may be used to increase the root



It is proved that n * 3 + 5N can be divided by 6


Using mathematical induction
(1) When n = 1, it is obviously true
(2) Suppose that when n = k, the proposition holds, that is, K ^ 3 + 5K is divisible by 6
When n = K + 1,
(k+1)^3 +5(k+1)=k^3+3K^2+3k+1 +5k+5
=(k^3+5k) + (3k^2 +3k) +6
=(k^3+5k) + 3*k(k+1) +6
(k ^ 3 + 5K) is divisible by 6 (hypothetical condition), 3 * k (K + 1) and 6 are divisible by 6
So it holds when n = K + 1



It is known that the two focal points of the ellipse are F1 - 2.0, F2 2.0, P is the point on the ellipse, and F1F2 is Pf1 and PF
It is known that the two focal points of the ellipse are F1 - 2.0, F2 2.0, P is the point on the ellipse, and F1F2 is the median of the equal difference between Pf1 and PF2. 1. Solve the elliptic equation. 2. If point P satisfies the angle f1pf2 = 120 degrees, find the area of triangle pf1f2


From the meaning of the title, we get Pf1 + PF2 = 2f1f2 = 2 * 2C = 4C = 8 = 2A
a=4,c=2,b^2=a^2-c^2=16-4=12
So the elliptic equation is x ^ 2 / 16 + y ^ 2 / 12 = 1
Let Pf1 = m, PF2 = n, then M + n = 8
F1F2^2=m^2+n^2-2mncos120=(m+n)^2-2mn+mn
4*4=64-mn
mn=48
So s (pf1f2) = 1 / 2mnsin120 = 48 * 1 / 2 * radical 3 / 2 = 12 radical 3



Fill in the brackets with prime number () + () = 35
Urgent!


Is there a mistake in this question, because the prime numbers within 35 are: 2 3 5 7 11 13 17 23 29 31
Any two sum will not be equal to 35, and 33 is not prime, you think about it
I think so



If a > 0, b > 0, and a + 2B = AB, then the minimum value of AB is
Note that Baidu can be found on the answer for 2, there is no such option, do not copy and paste this wrong fool


Because a > 0, b > 0, and a + 2B = AB,
So, AB > = 2 radical 2Ab
After simplification, the root sign AB > = 2, root sign 2
So, AB > = 8, if and only if a = 2B, the equal sign holds
So the minimum value of AB is 8
If you don't understand, you are welcome to ask,



Let f (x) = 4sin (2x + 1) - x, then ()
A. [-4,-2]B. [-2,0]C. [0,2]D. [2,4]


In the same coordinate system, draw the graph of G (x) = 4sin (2x + 1) and H (x) = x as follows: from the graph, we can see that the graph of G (x) = 4sin (2x + 1) and H (x) = x has no intersection point in the interval [- 4, - 2], and from the graph, we can see that the function f (x) = 4sin (2x + 1) - X has no zero point in the interval [- 4, - 2], so we choose a



When x takes what value, the value of (X-5) ^ 2 + (2x + 3) ^ 2 is equal to 36


(X-5) square + (2x + 3) square = 36 x square - 10x + 25 + 4x square + 12x + 9 = 36 5x square + 2x + 34 = 36 5x square + 2x-2 = 0 x = (- 2 + / - radical 44) / 10, so X1 = (- 1 + radical 11) / 5 x2 = (- 1 - radical 11) / 5
