When n tends to positive infinity, the limit is 1. When n tends to negative infinity, the limit is - 1
Given two functions f (x) = 8x ^ 2 + 16x-k, G (x) = 2x ^ 3 + 5x ^ 2 + 4x, where k is a constant. (1) for any x belonging to [- 3,3], there is f (x)
H(x)=G(x)-F(x)=2x^3-3x^2-12x+k
H'(x)=6x^2-6x-12=6(x-2)(x+1)
When h '(x) 45, f (x) = f (x) max, f (x1) = 141
Your first question that f and G are derivative functions, then after you seek the derivative, K has disappeared. What's the matter with k? Is there something wrong with the question
The second problem is to prove that the maximum value of F is less than the minimum value of G
If two vectors a and B are not collinear, and X (a + b) + y (a-b) = a + 4b, then the value of real number x, y
(x + y) a + (X-Y) B = a + 4b, so x + y = 1 and X-Y = 4 are left to calculate
If the root of the other equation is 2x + 2 + M = 4x 1-0
x1+x2=-4;
∴x2=-4-√3+2=-2-√3;
I'm very glad to answer your questions. Skyhunter 002 will answer your questions
If you don't understand this question, you can ask,
Let the other root of the equation be X2, then
x1+x2=-4
therefore
x2=-4-x1=-4-(√3-2)=-4-√3+2=-2-√3
The other root of the equation is - 2 - √ 3
x1+x2=-4/1=-4
X1 = radical 3-2
X2 = - 4-radical 3 + 2
=-2-radical 3
By using the Veda theorem X1 + x2 = - A / b
Root 3-2 + x2 = - 4
The solution is: x2 = - root 3-2
In the first semester of junior high school, what is the format of solving the equation of one variable and one degree?
That is to say, an equation is divided into: x =
That is the one that must be filled in
Example: 2x + 3 = 7
2x=7-3
2x=4
X=2
(x + P) & # 178; - (x + Q) & # 178; factorization,
(x+p)²-(x+q)²
=（x+p+x+q）（x+p-x-q）
=（2x+p+q）（p-q）
Given the function f (x) = 2x + 5x + 1, find f (- 1 / a)
Given the function f (x) = 2x + 5x + 1,
F (- 1 / 2 of a) = 2 / A & # 178; + 5 / A + 1 = (A & # 178; + 5A + 2) / A & # 178;
Given that vectors a and B are not collinear, real numbers x and y satisfy the equation x * (2a-b) + Ya = (Y-3) B + (3x-1) * a, then x =? Y =?
First of all, vectors a and B are not collinear, so the equation is arranged into the equation about a and B, that is: a (2x + y-3x + 1) - B (x + Y-3) = 0,
2X + y-3x + 1 = 0, x + Y-3 = 0, the solution is x = 2, y = 1
Let AB be an integer, and the root sign 3 - 1 be a root of the equation x square + ax + B = 0, and find the value of a + B
Let the other follow M
Then M + √ 3-1 = - A
m=1-A-√3
m(√3-1)=B
So a-1-3 + (2-A) √ 3 = b
(2-A)√3=B-A+4
On the right is an integer
Then the left side can only be √ 3, and the coefficient is 0
2-A=0
Then the right B-A + 4 = 0
A=2,B=-2
So a + B = 0
Wuhan, 2001) in China's stock market, an investor buys 1 & nbsp; 000 shares of Shanghai stock at the price of 10 yuan per share for 7.5% of all kinds of expenses for each purchase and sale. When the stock rises to 12 yuan, all the shares are sold. The investor's actual profit is ()
A. 2000 yuan B. 1925 yuan C. 1835 yuan D. 1910 yuan
(12-10) × 1000-10 × 1000 × 7.51000 − 12 × 1000 × 7.51000 = 1835 yuan, so the investor's actual profit is 1835 yuan
