Once, after PE class, the students rushed back to the classroom to drink water, but my water product was too hard to open. At this time, the students saw me and helped me. I took the bottle cap and twisted it to the left. Another student twisted it to the right. After a while, the water bottle opened. When I drank the clear water, I felt another special sweet taste!

The grandmother who loved her flew away happily with the little girl in her arms
Think about writing
The first meaning of happiness is that the little girl is happy when she is in the beautiful illusion before she dies; the second meaning of happiness is that the little girl is completely happy when she dies without cold, hunger and pain

Given the function f (x) = Ba ^ x (where a, B are constant, a & gt; 0 and a ≠ 1), the image passing through a (2,12), B (- 1,3 / 2) is correct
Given the function f (x) = Ba ^ x (where a and B are constants, a > 0 and a ≠ 1), B (- 1,3 / 2) (1) finds the value of a and B (2) if the function g (x) = √ (1 + A ^ x-mb ^ x) is meaningful when x belongs to (- infinity, 1), finds the value range of real number M

(1) The image of function f (x) = Ba ^ x passes through a (2,12), B (- 1,3 / 2)
So 12 = b * a ^ 2 2 / 3 = b * 1 / A
Do ratio a ^ 3 = 8, get a = 2, B = 3
(2) G (x) = √ (1 + A ^ x-mb ^ x) is meaningful when x belongs to (- infinity, 1]
So, 1 + 2 ^ x-m * 3 ^ x > = 0
Because 2 ^ x > 0, 3 ^ x > 0, (1 + 2 ^ x) / 3 ^ x > = m
m

Two fifths of x plus x equals five fifths of X what is it

Two fifths of x plus x equals five fifths of seven
7x out of 5 = 5 out of 7
X = 5 / 7 △ 7 / 5
X = 25 / 49

1. Let the probability density of two-dimensional random variables (x, y) be, ask whether X and y are independent of each other, and explain the reason

1fx=int（-oo,+oo）f（x,y）dy=1
fy=int（-oo,+oo）f（x,y）dx=0.5e^（-0.5y）
F (x, y) = FX * FY, independent
Uniform distribution on 20-8
EX=int (0,8)x/8dx=4
EX^2=int (0,8)x^2/8dx=64/3
DX=EX^2-(EX)^2=16/3
3 EXi=0.03,DXi=0.03,EZ=1.5,DZ=1.5
N(1.5,1.5),P(Z>=3)=1-P(Z

The difference between * and. * in MATLAB. For example, y = 2 * exp (- 0.5 * x). * cos (4 * pi * x)

In MATLAB, * is matrix multiplication,. * is the number multiplication of the corresponding position of the sequence, a = [123]; b = [234]; a. * banks = 2612 and a * B is wrong. Matrix multiplication requires that the number of columns of a and the number of rows of B are equal, and returns that the number of rows of a is equal to the number of columns of B, and there is a scalar between a and B

Two out of seven plus two out of seven equals four out of seven. Write two more multiplication

One seventh multiplied by one seventh is one forty-nine

In the figure below, the side length of each small square is 1cm. Draw a rectangle, the circumference is 20cm, and the ratio of length to width is 7:3
What's the length and width of a rectangle

The sum of length and width of rectangle = 20 △ 2 = 10 (CM)
Length of rectangle = 10 × 7 △ 7 + 3 = 10 × 7 / 10 = 7 (CM)
Width of rectangle = 10-7 = 3 (CM)
40 minutes: 5 / 3 hours
=2 / 3 hours: 5 / 3 hours
=2：5
=0.4

How can quadratic function transform general form into vertex form

Y = ax & # 178; + BX + C, which is changed into vertex form: y = a (x + B / 2a) &# 178; + (4ac-b & # 178;) / 4A
The formula process is as follows: y = ax & # 178; + BX + C
=a(x²+bx/a)+c
=a(x²+bx/a+b²/4a²-b²/4a²)+c
=a(x+b/2a)²-b²/4a+c
=a(x+b/2a)²+(4ac-b²)/4a
If you don't understand, please hi me,

If X & sup2; + ax + 4 is a complete square, then a =?; if 4x & sup2; + 12xy + m is a complete square, then M =

If x2 + ax + 4 is a complete square, then a = 4 or - 4, then the complete square is (x + 2) ^ 2 or (X-2) ^ 2
4x2 + 12xy + M = (2x) ^ 2 + 2 * 2x * 3Y + m is a complete square, then M = 9y ^ 2
