5. We know that a = 7.5, B = 2, C = 3.6, the expression! The value of C > b is________ ? Can you explain for me what C means?
! C is a logical operation, which is to judge whether a proposition is true or false, "false" is represented by 0, and "true" is represented by 1, so there are only two values of logical operation, 0 and 1.! C is a negative operation on C, if and only if C is 0, the value of! C is 1, which means that when C is 2, or a, or other values are not 0, the value of! C is 0, As long as the value is not 0, it is true
! C > B contains two operations, one is logical operation, the other is relational operation
Calculation priority you can read books, more specific, hand party must not ah
The operation result of! C > b is 0, because! C is 0, 0 > b is equivalent to 0 > 2, which is obviously not true, and the value is 0
Given a = 7.5, B = 2, C = 3.6, then the value of the expression a > b & & C > a | AB is
0
FALSE
false
In the following options, the expression with a value of 1 is () a.1 - '\ 0' B.1 -'0 'C.' 1 '- 0 D.' 0 '-'0'
In the following options, the expression with a value of 1 is ()
A.1-'\0' B.1-'0' C.'1'-0 D.'\0'-'0'
By the way, it's okay not to
The result we want to get is the difference between two values in memory
Don't mislead us by the way they appear in front of us. It's just for convenience
A: The '0' ASCII value is 0, so 1-0 = 1
B: '0' ASCII value should be 48 (seemingly) value, not 1
C: '1' - 0 ditto
D 0 - 48 != 1
Simple 1.65 times 43 plus 1065 times 57
1.65*43+1065*57
=1.65*(100-57)+1065*57
=165-1.65*57+1065*57
=165+1065*57-1.65*57
=165+(1065-1.65)*57
=165+1063.35*57
=60775.95
What does Lagrange mean value theorem mean?
It refers to the slope of the straight line connected by the two ends of the interval (a, b). This theorem means that if it is continuous on the closed interval and differentiable on the open interval, then there is always a value that can make the slope of the known curve equal to that of the straight line, and the other slopes will be larger or smaller than this. In fact, if you have seen Rolle's theorem, you will understand the meaning of the median value better, In that theorem, the mean value means that the slope is 0
The density of oxygen in a steel cylinder is 8 kg / m3, and 1 / 5 oxygen pressure is used for one welding
If the density of oxygen in a steel cylinder is 8 kg / m3 and 1 / 5 is used in one welding, will the oxygen pressure in the cylinder increase or decrease or remain unchanged?
Because the cylinder is filled with liquid oxygen, so the liquid pressure formula
Pressure = density * g * height
Because the liquid is difficult to compress, the volume is not easy to change, so the density remains unchanged
G is a constant
And because of the 1 / 5 height reduction of electric welding
So the pressure becomes smaller
I hope it will be useful to you
A new operation is defined: a * b = 1 - A + B of AB, then 2 * 3 = [
a*b=1-(a+b)/ab=1-1/a-1/b
2*3=1-1/2-1/3=1/6

What are the light years and astronomical units
Light year, a unit of length, is generally used to calculate the distance between stars. Light year refers to the distance that light travels in a vacuum for one Julian year. It is calculated by time and speed
Astronomical unit (AU) is a unit of length, approximately equal to the average distance between the earth and the sun. It is one of the astronomical constants. In astronomy, the basic unit for measuring distance, especially the distance between celestial bodies in the solar system. The average distance between the earth and the sun is an astronomical unit. An astronomical unit is about 149.6 million kilometers
