There is a contradiction
Change to
The campus is very lively

The playground of this school is lively and quiet

The school playground is sometimes lively and sometimes quiet

After school, the campus is quiet
I really don't know how to change it

After school, the campus is very quiet
Peace is the word of illness here

After school, the campus is very quiet

Late autumn dusk, I walk in the quiet campus, only to see the flowers withered, leaves dried up, bare trees languidly hanging on the trunk, the former green hairy grass is now just a yellow. Walking on the campus, I see the whole campus has become a world of silver makeup, standing buildings covered with white, small saplings

3388 is 24
How to calculate 24:00 with two three, two eight?

8 ÷ (3 - 8 ÷ 3)

The problem of the translation of the graph of a function "left plus right minus, up plus down minus". Why is this law derived?
Let's not talk about quadratic function, we only learn the function once,

Let's take the line y = x as an example. The line goes through (0.0)
When the line moves one unit to the left, then y = (x - (- 1)). Can you understand y = x + 1
When the line moves 1 unit to the right, it moves from the origin to the positive half axis of X
The equation is y = X-1
When the line moves up by 1 unit, the line moves up by 1 unit from the Y axis, and the line passes (0.1)
Is Y-1 = x y = x + 1
If you move down, it's y + 1 = x, so y = X-1
You can draw a picture of this kind of topic by yourself

Cut a 2-meter-long cylinder wood into three sections, and the surface area increases by 8 square decimeters. What is the volume of this wood cubic decimeters?

Bottom area: 3-1 = 2 times, 2 * 2 = 4 sides
8 / 4 = 2 square decimeters 2 meters = 20 decimeters
S: 2 * 20 = 40 cubic decimeter

3. 5, negative 4 and 2 are 24 points

Negative 4x (2-3-5) = 24

Calculation of derivative instantaneous velocity
Displacement s (T) = 0.3T ^ 3 + 8t ^ 2 + 16t
Find: (1) the instantaneous velocity at the end of 2S; (2) the instantaneous acceleration at the end of 2S
Please look at the next question
Displacement s (T) = 0.2T ^ 3 + 8t ^ 2 + 16t
Find: (1) the instantaneous velocity at the end of the second second second and (2) the instantaneous acceleration at the end of the second second second.

The first derivative of displacement is velocity and the second derivative is acceleration
v(t)=s(t)'=0.3*3t^2+8*2t+16
Substituting t = 2 is the result
a(t)=s(t)"=0.9*2t+16
Substituting t = 2, even if the instantaneous acceleration
It's the same
(t)=s(t)'=0.2*3t^2+8*2t+16
Substituting t = 2 is the result
a(t)=s(t)"=0.6*2t+16
Substituting t = 2, even if the instantaneous acceleration

How many square meters is 4.8 yuan per thousand square inches
How is this calculated? Please ask
How many thousand square inches is 4.8 yuan per square meter

1 square inch
= 0.0254 × 0.0254 = 0.00064516 M2
Thousand square inches = 0.64516 square meters
4.8 yuan / thousand square inches = 4.8/0.64516 = 7.44 yuan / square meter
