Am I wrong again? Can anyone help with the analysis

Why do I feel that this phenomenon is like "power politics" in economics?

Actually, I think two people should be harmonious when they are together. A person can do whatever he wants, but after all, two people are two different people (twins can't be exactly the same), and there will be differences in living habits, behavior, etc., so both parties need to tolerate and understand each other.

The life of two people is only one side of the change, and the other side of the effort is not enough, it requires the joint efforts of both parties. You can find a time for the two of you to talk openly and honestly, which is necessary for the rest of your life.

Moreover, arguing about buying gifts, the question is not magnified. When dealing with problems, we must reduce the big things to the small ones, and the small things to nothing. Besides, this buying a gift doesn't seem to be a big deal, it's not a matter of principle, so don't worry about it, right? You tell me?

Wishing you happiness!

As long as both parties face the problem positively and deal with the problem in a happy mood, it is not a big deal.

What you said above made me not realize that you were strong, but that he was strong. Hehe! The two of them get along with each other a little bumpy, which requires two people to tolerate each other, one person can not get along well, change slowly, don't be in a hurry, he will understand one day with this heart, hehe!

After reading your story, I think yours is not wrong, but you used the wrong method, because you are not married, he is good to your family because he needs to be recognized and favored by your family, he wants to take you, let him do this, as for you? Seriously, you don't have to go through his consent to buy anything for his family. He's a man after all, right?

You ask him, and of course he says no. However, if you do buy it quietly, he will be happier. Because that's your heart!

It is not easy for the two to come together. Don't be unhappy about these little things, understand him more, and sometimes you can do whatever you want! If you always have to ask him, he will be annoyed, and second!

He will feel that you are not sensible. It's true. Because he loves you very much, he also loves your family, but you also love him, so you will also love his family, and it is not a courtesy to buy things for them, that is because you both love each other, so you love each other's family more, and give them some warmth.

Think about it! Don't blame him, let alone yourself, the important thing is understanding and tolerance. And what's more important is to love each other.

There is nothing wrong with this question, the problem is 2n+1, which is a simple sum of a series of equal differences. It should be option C. There are a total of n+1 items here.

It's not a mistake. This question does not say the range of n, so it can be equal to 0. Of course, you can also understand that 2n+1 is the n+1 term of the series, and the general term formula of the series is 2n-1. So the answer should be option C.

The answer is c, you ignore the previous 1, and you take the number casually.

Such a person has no education, so he can only say so. It would be good to have such an experience once, and if she has similar requests in the future, it is recommended to stay away from refusal.

Love is like this, fake to false, sincere and sincere! In times of disaster, talents taste the hot and cold of the world; When needed, talent sees through the truth and falsehood of love. All your efforts have become a burden in the eyes of the other party, when you are stupid and selfless to be good to him, but in exchange for heart-wrenching pain, this relationship you spent your youth teaching him how to love others, replaced by endless pain, the most humble is that you love him, he doesn't love you.

Such a person is too selfish, he always likes to eat more and occupy more, just ignore her.

Women of any age like flowers, but choose flowers with some thought, don't exaggerate, after all, it's the first time you meet, it's best to be a small bouquet, which means that you can put your heart into it. In addition, don't send cosmetics and perfumes lipstick, etc., these things are easy to displease if you don't particularly understand the style that ladies like, so it's best not to, unless you have good taste or women of any age like flowers, but choose flowers to put some thought, don't be too exaggerated, after all, it's the first time to meet, it's best to be a small bouquet, on behalf of your heart. Also do not send cosmetics and perfumes lipstick, etc., these things are easy to displease if you are not particularly familiar with the style that ladies like, so it is better not unless you have good taste or.

In this question, the resistance of the filament is given two values, 2 and 20, both of which are not the resistance of the filament when the lamp is shining normally. The resistance of the lamp when it glows normally can be calculated by dividing it by 4 V. Therefore, when answering, it is necessary to pay attention to the correct data substituted into the calculation formula, otherwise there will be errors.

The first three spaces are required to be normal light emitting data, so the data that can be used are 220V, 4 V, and 3600S, which can be calculated by the voltage division characteristics of the series circuit, and there should be 55 small colored lights in series. So the total resistance is multiplied by 55 about 733. The electrical energy consumed in 1h is 220V, and the three physical quantities are multiplied, so it should be 237600J.

When one of the small colored lantern filaments burns out, the voltage at both ends of the thin metal wire reaches 220V, the copper oxide is broken down, the thin metal wire and the filament holder are turned on, and the remaining lamps shine again.

2 and 20 in the problem are two redundant conditions, it is not used in the calculation process, 20 is greater than the resistance of the lamp when it emits light normally, which shows that when the voltage actually added to the lamp at both ends is greater than the rated voltage, when the brightness of the lamp is bright, the resistance value of the filament will be much higher, but the filament will not easily burn out.

And why is the total resistance 1100?

Because it is 55 20 ohms = 1100 ohms of thin wire with a voltage of V at both ends

How to write this ·· Landlord, I don't want it.

The original formula is: x squared -6x + y squared +8y+25=0xsquared -6x +9 +ysquared +8y+16=0 [hint: divide 25 into 9 and 16].

x squared -2 · 3·x + 3 square )+y squared + 2 · 4·y + 4 squared) = 0

x-3) square + y+4) square = 0

x-3=0y+4=0

i.e. x=3y=-4

I'm glad to solve the above problems for you, I hope it will help you with your learning! Hand Feast].
