What are the methods to prove the continuity and differentiability of functions?

For a function of one variable, continuity, 1. If its derivative exists, it must be continuous; 2. Definition: left continuous = right continuous = function value
Differentiability, 1. Definition; 2. For primary functions, they are all differentiable

24. The operation result of expression 16 + 63% 4 * 3 is______ (1 point) a, 27 B, 25 C, 19 D, 6

16 + 63 % 4 * 3
= 16 + 3 * 3
= 16 + 9
= 25
The answer is B

A cylindrical water pipe has a diameter of 20 cm. If the speed of water flow is 3.5 meters per second, how many cubic meters of water can this pipe flow in one minute?

This topic is about the volume of a cylinder,
The known conditions are as follows
Diameter of water pipe (cylinder) = 20cm = 0.2m radius = 0.1M
Length of water pipe (height of cylinder) = 1 minute * 3.5 m / S = 60 seconds * 3.5 m / S = 20 meters
According to the volume formula of the cylinder, there are:
V = bottom area * height
=3.14 * square * height of circle radius
=3.14*0.1*0.1*20
=0.628 M3
This pipe can flow through 0.628 cubic meters of water in one minute

The function problem f (x) = x / ax + B (a, B are constants, a is not equal to 0),
Given the function f (x) = x / ax + B (a, B are constants, a is not equal to 0), if f (2) = 1, and f (x) = x has a unique solution: find the analytic expression of F (x)
Wrong, and the other one is f (x) = 1

F (x) = x / (AX + b), (a, B are constants, a is not equal to 0),
If f (2) = 1, and f (x) = x has a unique solution
f(2)=1=2/(2a+b),b=2(a-1).
If f (x) = x, x = x / (AX + b), then
Ax ^ 2 + (B-1) x = 0, if the equation has a unique solution, then it has
⊿=0
(b-1)^2-4*a*0=0,
b=1,a=1/2.
In other words, the analytic expression of F (x) is: F (x) = x / [(x / 2) + 1]
2) Because: if f (2) = 1 and f (x) = x has a unique solution, then
f(1)=1,
1=1/(a+b).(1)
However, f (2) = 1 = 2 / (2a + b),
b=2(a-1).(2)
By solving (1) and (2), we get that,
a=1,b=0,
Then f (x) = x / (x + 0) = 1
In other words, the analytic expression of F (x) is: F (x) = x / [(x / 2) + 1], or F (x) = 1

There are 30 boys and 4 / 9 girls in class 61. How many are there in the class?

54
30*9/5=54
Set the class size as X
It is concluded that x * (1-4 / 9) = 30
Simplified x * 5 / 9 = 30
5X=270
X=54

Calculation of 8,65 - (3,5-0,35) with simple method

=8.65-3.5+0.35
=8.65+0.35-3.5
=9-3.5
=5.5

When the angle between them is 90 degrees, the resultant force is F. when the angle between them is 60 degrees, the resultant force is ()
A. 2FB. 62FC. 32FD. 22F

When the angle between two forces is 90 degrees, f = f, according to the parallelogram rule and triangle knowledge, F1 = F2 = 22F; when the angle between two forces is 60 degrees, according to the parallelogram rule, the resultant force is 62F, so B is correct, a, C, D are wrong
