If f (x) = xsquare - 2x + 2, then the relation between F (- 1) and f (π) is?

If f (x) = xsquare - 2x + 2, then the relation between F (- 1) and f (π) is?

f(x)=(x-1)^2+1
The axis of symmetry is 1
The farther away from 1, the greater the y
f（-1）

At a certain moment, the shadow of flagpole AB is partly on the ground, and the other part is on the wall of the building. Xiaoli measured that the shadow length BC of flagpole AB on the ground is 20m
The shadow length CD on the wall is 4 M. at the same time, Xiaoli measured that the shadow length of the 1 m long pole standing on the ground is 0.8 M. please help Xiaoli find out the height of the flagpole

----------- = -----------
0.8 20+3.2 Y=29M
The flagpole is 29 meters high

0.8A*5A=?

(0.8 * 5) a * a = the square of 4A

To draw a school plan, which of the following scales is more appropriate
A 1:1000
B 1:4000000
C 1:3000000
D 1:200000
In my opinion, the school plan should be relatively simple, with a larger scope and smaller scale
But there is also an idea that the scope of the school plan is smaller, so the scale is larger
What do you think

A 1:1000
What's smaller?
Playground 400 × 400m
A thousand times smaller is four decimeters, just right

People with imagination but no knowledge are like birds with wings but no feet. They can't stop! It's better to travel thousands of miles than to read thousands of books! But really? Books are the feet that allow you to stop and have a rest when you are tired. Without that foundation, there is no way to travel far! Books, like a pair of thousand mile eyes, let us understand the world; books, and

It's about 38 kilograms

As shown in the figure, rotate the equilateral triangle ABC 180 ° around the center of rotation to get △ def, then the ratio of the area of the overlapping part of △ ABC and △ def to the area of △ ABC is______

What is the axis of symmetry of the line segment?

The midpoint of a line segment

5x^3y(x-y)^3-10x^4y^3(y-x)^2
Factorization

5x^3y(x-y)^3-10x^4y^3(y-x)^2
=5x^3y(x-y)^3-10x^4y^3(x-y)^2
=5x^3y(x-y)^2[(x-y)-2x]
=5x^3y(x-y)^2(-x-y)
=-5x^3y(x-y)^2(x+y)
