Proton is a kind of microscopic particle. The mass of a proton is about 1.672623 * 10 to the - 27th power kg (keep 4 significant numbers, take approximate value, and use
Scientific notation)

672623 * 10 to the power of - 27 kg,
It's 1.673 * 10 to the - 27th power kg

The title is [the inequality x ^ 2 + 2aX + 4 ＞ 0 about X, for all x belongs to R constant, find the value range of A.]
In the reference answer, it says △ = (2a) ^ 2-4 × 4 < 0. Why?
What does it mean that x belongs to R constant? Why should △ be less than 0?
o(∩_ ∩)o

The inequality can be regarded as the function y = x ^ 2 + 2aX + 4, where x belongs to R, the values are greater than 0. If the opening of the function is upward, then △ 0 has no intersection with the X axis, and the image is all above the X axis, so the inequality is always true when x belongs to R

Mathematics problems in grade one of junior high school
A fire broke out in a three story building. A fireman climbed to the third floor with a ladder to rescue things. When he reached the first level in the middle of the ladder, a fire came from the second floor window, and he retreated three levels. When the fire passed, he climbed up seven levels again. At this time, two bricks fell from the roof, and he retreated two levels again. Fortunately, he didn't hit him, and then he climbed up eight levels again, Q: how many steps does this ladder have? How many steps does he go up and down?

Let half the length of the ladder be X
0.5x-3+7-2+8=x
The solution is x = 22
The length of the ladder is 22
He walked 0.5x + 3 + 7 + 2 + 8
0.5X=11
11+3+7+2+8=31

If f (x) = x & # 178; + 2 (A-1) x + 2 decreases in the interval (∞, 4), what is the value range of a?
I hope to give a specific analysis process,
The correct answer is a

Opening up
So it decreases to the left of the axis of symmetry x = - (A-1)
So the axis of symmetry is on the right side of the decreasing interval
So 4 ≤ - (A-1)
a≤-3

The absolute value of y = (M + 1) x ^ m + M-1 is a linear function, M =?

The absolute value of y = (M + 1) x ^ m + M-1 is a linear function
Then the coefficient of X is not 0 and the exponent of X is 1
obtain
M + 1 ≠ 0 and the absolute value of M = 1
That is, m ≠ - 1, tangent M = plus or minus 1
So m = 1

The increasing interval of the function y = Log1 / 2 (12-4x-x & # 178;) is?

Domain 12-4x-x & # 178; > 0
x²+4x-12＜0
(x+6)(x-2)＜0
-6＜x＜2
Because for y = Log1 / 2, X is a decreasing function on x > 0
Therefore, in order to make y = Log1 / 2 (12-4x-x & # 178;) monotonically decreasing, only the increasing interval of 12-4x-x & # 178; is needed
The increasing range of 12-4x-x & # 178; = - (x + 2) &# 178; + 16 is (- 6, - 2]
So the increasing interval of the function y = Log1 / 2 (12-4x-x & # 178;) is (- 6, - 2]
