Wang Zhuang's weight is 39 kg. How many kg does his blood contain?

39 × 113 × 23 = 2 (kg) a: his blood contains about 2 kg of water

What are the characteristics of the function y = f (x) at the point where the derivative does not exist

It means that the point is not differentiable
A necessary and sufficient condition for a function to be differentiable is that its left and right derivatives exist and are equal
From this we can judge whether it is derivable or not
For example, f (x) = | x |, X belongs to R. (drawing)
The function is continuous on R, but its derivative does not exist at x = 0, because its left derivative (- 1) and right derivative (1) are not equal

Junior high school mathematics problem solving equation 2x + 3 / (x-1) - 5 / x = 6

Double x (x-1)
(2x+3)x-5(x-1)=6x(x-1)
2x²+3x-5x+5=6x²-6x
4x²-4x-5=0
x=(1±√6)/2
The fractional equation needs to be tested
By testing, x = (1 - √ 6) / 2 and x = (1 + √ 6) / 2 are the solutions of the equation

The angle alpha and the angle beta are complementary angles to each other. Their degree ratio is 2:3. Find the difference between the complementary angles of the angle alpha and the angle beta

Let α = 2x, β = 3x,
Then, from ∠α + ∠β = 90 ° to 2x + 3x = 90 °,
5x=90°,x=18°
∴∠α=36°,∠β=54°
The complementary angle of ≠ α is 144 ° and the complementary angle of ∠ β is 126 °
144°-126°＝18°
The difference between the complements of the two angles is 18 degrees

Let f (x) = 2 ^ x + 3 ^ X-2, X - > 0, then what is the relationship between F (x) and X infinitesimal?
equivalence
high price
Same price
low price
How exactly?

lim[f(x)/x]
=lim[f'(x)/x']
=lim(2^xln2+3^xln3-2)/1 (x->0)
=ln2+ln3-2
=Constant
So they are infinitesimals of the same order
But the strict method is to expand f (x) with Taylor's formula. I forgot, but I'm sorry~

Who knows what's the rule from one plus two plus three plus four plus five plus six plus seven plus eight plus nine?

The summation formula of arithmetic sequence: the number of first term plus last term multiplied by 2

What are the numbers after 4,3,1,12,9,3,17,5

4-3=1
12-9=3
17-5=12
So the last one should be 12

What is the minimum value of the three forces of 5n.7n.9n

The minimum value is zero
9N can be synthesized from 5N and 7n, then 0n can be synthesized from 9N

If the first five terms of the sequence an are 1,1,3 / 2,2,5 / 2, then a general term formula an of the sequence {an}=

A1 = 1, A2 = 1, A3 = 3 / 2, A4 = 2, A5 = 5 / 2, so a2-a1 = a3-a2 = a4-a3 = a5-a4 = 1 / 2, so this is an arithmetic sequence, the first term A1 = 1 / 2, tolerance 1 / 2, an = 1 / 2 + 1 / 2 (n-1) = n / 2, an = n / 2
