Have you ever been to Disneyland
Most of us may have heard of Mickey Mouse, Donald Duck and many other famous Disney characters. Maybe we have even seen their movies, but have you ever been to Disneyland? In fact, there are several different Disneyland amusement parks around the world. Disneyland is an amusement park, but we can also call it a theme park, You can find all the normal attractions in an amusement park, but there is also a theme of Disney movies and Disney characters. For example, you can see the ferris wheel in some other parks, but there is a theme of Disney characters on the ferris wheel in Disney park. This means that you can see Disney characters anywhere on the ferris wheel, You can also watch movies about Disney, eat in Disney restaurant, buy Disney gifts, and you can see Disney characters walking back and forth in Disneyland at any time! Have you ever heard of Disney sailing? This is a big ship with Disney theme. You can take a boat for a few days, And you can sleep and eat on the deck. Like Disneyland, there are many attractive places where you can shop, go to Disney parties and have dinner with Mickey Mouse! This boat has several different routes, but they all end up in the same place. That's the island that belongs to Disneyland!

In the same plane rectangular coordinate system, if the intersection of the line y = 3x-1 and the line y = x-k is in the fourth quadrant, then the value range of K is ()
A. K ＜ 13b. 13 ＜ K ＜ 1C. K ＞ 1D. K ＞ 1 or K ＜ 13

The solution of the system of equations y = 3x − 1y = x − k about X and Y is: x = 1 − k2y = 1 − 3k2 ∵ the intersection point is in the fourth quadrant ∵ the system of inequalities 1 − K2 > 01 − 3k2 < 0 is obtained; the solution is 13 ∵ K < 1, so B is selected

The size of the two squares are placed as shown in the figure. The shadow part is the overlapping part. What is the area of the blank part? (unit: cm)

22 × 22 + 15 × 15-7 × 7 × 2, = 484 + 225-98, = 611 (square centimeter); answer: the blank area is 611 square centimeter

The image of the quadratic function y = x2 + BX + C is shifted 2 units to the left, and then 3 units to the upper. The analytic function y = x2-2x + 1 is obtained, then B and C are equal to ()
A. 2，-2B. -8，14C. -6，6D. -8，18

From the Title Meaning: X ′ = x − 2Y ′ = y + 3, substituting into the original parabolic equation: y '- 3 = (x' + 2) 2 + B (x '+ 2) + C, after sorting out and comparing with y = x2-2x + 1: 4 + B = − 22b + C + 7 = 1, the solution is: B = − 6C = 6

Given m = {y | y = x & # 178; - 4x + 3, X ∈ r}, n = {y | y = - X & # 178; + 2x + 8, X ∈ r}, the answer to m ∩ n is {y | - 1 ≤ y ≤ 9}

y=x*x-4x+3=(x-2)*(x-2)-1>=-1;
y=-x*x+2x+8=-(x-1)*(x-1)+9

（a4-b4）4/((a2+b2)2.(a2-b2)2)

（a4-b4）^4/((a2+b2)².(a2-b2)²=[(a²+b²)^4*（a²-b²)^4]/(a2+b2)².(a2-b2)²=(a²+b²)²*(a²-b²)²=(a^4-b^4)²=a^8-2a^4b^4+b^8

As shown in the figure, in △ ABC, the vertical bisector of edge AB intersects point E, and the vertical bisector of edge AC intersects point D. if BC = 8, find the perimeter of △ ade

Junlang lieying team for you
∵ D and E are the intersection of the vertical bisector of AB and AC and BC respectively,
∴AD=BD,AE=CE,
∴CΔADE=AD+AE+DE=BD+CE+DE=BC=8.
That is, the perimeter of Δ ade is 8
