Given that 1 ＜ x ＜ 2, a = 2 ^ x, B = log0.5 (x), C = √ x, compare the size of a, B, C, and explain the reason

Given that 1 ＜ x ＜ 2, a = 2 ^ x, B = log0.5 (x), C = √ x, compare the size of a, B, C, and explain the reason

∵1

If x ^ 2 = - K / 4, how much is this x equal to,

x^2=-k／4
If k > 0, then = - K / 4 < 0, so there is no solution
When k < 0, x = ± √ (- K) / 2

Decomposition factor A ^ 2-B ^ 2-4a + 6b-5

The motorcycle wheels rotate rapidly and look like a whole plane, which shows that______ ．

A wheel is like a round surface, which is formed by rotation of an axis. This axis is regarded as a line

Equation of line and circle, tangent equation of circle through point
The tangent equation of circle (X-2) square + (Y-1) square = 1 passing through point a (3,4) is (c)
c. 4x-3y = 0 or x = 3
4x-3y = 0, I'll ask
How to get x = 3? The slope does not exist? If the slope does not exist, then it is not y = KX + B? It should not be y = how much~
My food

Y = B, that is, the slope is 0, and the slope does not exist is in the form of x = A. generally, when finding a straight line, there are two cases, one is y = KX + B (the slope exists, including y = B, as long as k = 0) and the other is x = a (the slope does not exist, that is, perpendicular to the X axis). As long as these two cases are discussed, the solution will not be missed

Team a and team B carried a batch of goods together. Team a carried 5 | 8 of the total, while team B carried 2 | 5 of team A. what percentage of the goods were left?
The answer! Now

5/8×2／5=1／4
5／8＋1／4=7／8
1－7／8=1／8

If the solution of the equation 5x + 2A = 0 about X is 2, please find the value of the equation Ay-2 = 2A + (A-1) y about y

The solution of the equation 5x + 2A = 0 about X is 2
10+2a=0
a=-5
Substituting into the equation: Ay-2 = 2A + (A-1) y
-5y-2=-10-6y
y=-8

In the first time, 24.7 tons were used, and in the second time, 9.4% of a ton was used, leaving 8.6 tons. How many tons of yellow sand are there?
A bucket of detergent, used 4 and 3 / 4, the rest is 1.44 kg more than used, how many kg of this bucket of detergent?
A steel pipe is 40 meters long and sawed into three sections. The first section is 9 and 1 / 2 long, 5.25 meters shorter than the second section. How long is the third section?
In an orchard, there are five kinds of watermelons, one third of apples and the rest of strawberries. How many kinds of strawberries account for in this orchard?

8.6 + 9 and 1 / 4 + 24.7
=8.6+9.25+24.7
=42.55 (T)

Given the line L: 3x-4y + 12 = 0, what is the linear equation about X-axis symmetry and y-axis symmetry

On X-axis symmetry, X is invariant, and Y is replaced by - Y
3X-4(-y)+12=0
3x+4y+12=0
For Y-axis symmetry, y is invariant, and X is replaced by - X
3(-X)-4Y+12=0
-3x-4y+12=0
3x+4y-12=0

There are 64 people in the first workshop and 56 people in the second workshop of a factory. Now, due to work needs, the number of people in the first workshop is half of that in the second workshop. How many people need to be transferred from the first workshop to the second workshop?

Suppose you need to transfer x people from the first workshop to the second workshop, according to the meaning of the question: 2 (64-x) = 56 + X, the solution is x = 24; answer: you need to transfer 24 people from the first workshop to the second workshop
