A barrel of oil weighs 32 kg. After half use, it weighs 17 kg. How much is the barrel? How much is the oil?

Half is 32-17 = 15kg
Oil 15 * 2 = 30kg
Barrel 32-30 = 2kg

What is the continuity of function? How to prove the continuity of function?

If the function f (x) at a point x0 in the domain of definition satisfies the limit of F (x) = f (x0) when x tends to x0, then f (x) is said to be continuous at that point. As for proving the continuity of function, we use this definition to prove it. In fact, when we really use the continuity, it is derived from the continuity of those basic functions, and basically no proof is needed

VB calculation problem, expression 4 + 5 / 6 * 7 / 8mod9 = 5, why

The calculation process and sequence are as follows, see if you can understand, can leave a message
4+5\6*7/8Mod9
=4+5\42/8mod9
=4+5\(5.25)mod9
=4+5\5mod9
=4+1mod9
=4+1
=5
