My Identity As A Schoolmaster Has Been Exposed

Chapter 180 Do the college entrance examination questions? Three minutes is too much!

Soon, the three technicians came over and said to him: “Boss, it’s all done!”

Han Honghu glanced at them lightly and said, “Okay, wait for you to get in the car.”

He is going to say goodbye to Xu Cong’s family.

“Mr. Xu, Mrs. Xu, and Teacher Xu, if you have anything, just call me!”

This title is a bit strange! Han Honghu left the number with someone.

After a few people left, Xu Junshan’s eyes were staring, and he was so excited that he didn’t know what to say, and stared at Xu Cong with Zhou Xiuyun.

“Son! You really are fighting for our family!”

“Son, you are great! To be your mother, I am really a blessing that I have cultivated in ten lifetimes!”

Just when they were excited, the village party secretary came.

He looked embarrassed and suddenly raised his head. He was even more surprised when he saw the painted out painting on the wall of Xu Cong’s house.

“This, this, such a good painting, why have you erased it!”

Zhou Xiuyun turned black when she saw that he was coming, and she said with some dissatisfaction: “The village party secretary, why are you here again? Our Xu Cong won’t paint for you anymore! You should go back!”

Xu Cong also didn’t entangle with the village party secretary, he went back to the house. When I have time to listen to the village party secretary, Xu Cong might as well be with Lin Mengjiao.

…

The village party secretary looked at Zhou Xiuyun and then at Xu Junshan. Xu Junshan didn’t know the cause of the incident, so he asked, “What happened?

Zhou Xiuyun told him the ins and outs of the matter: “My son went to paint before, and he didn’t want a penny. The village party secretary disliked it and said it was not good, so he refused, and paid for himself to find someone to paint.”

“Now those people can’t draw pictures like our Xu Cong, the village party secretary just wants to come to us!”

“Do you think of our Xu Cong as a ball? You kick it around!”

The village party secretary was embarrassed, his face was full of apologies, and said to her: “I’m sorry, I’m sorry, I haven’t seen your Xu Cong painting so beautiful!”

“I admit that when I came last time, I saw him drawing on the wall. I didn’t have a clue. I thought he was scribble, so don’t be angry!”

“Junshan, you are a master, you are in charge, you help me persuade, okay?”

When Xu Junshan heard this, he immediately waved his hand and said, “No way, no way! What kind of home should I be! Our family is headed by our son!”

When the village party secretary heard the bastard remarks, he was so angry that he said to him, “You are a man, why are you not in charge? Don’t be kidding, how come your family Xu Cong is in charge?”

Xu Junshan, who is serious, without the slightest intention of joking, said very seriously: “The village party secretary, I will say it again! Our family! My son is the master! I listen to my son!”

joke!

Laozi turned over the small villa! This home, he really deserves it!

“Can’t I apologize to you? Think about it! I am willing to give money, I am really willing to pay! You can help the village, and you can keep a good reputation!” The village party secretary pleaded again.

After Xu Junshan learned the whole story, he said with a bit of grievance: “No need! The village party secretary, if you keep this money, please ask Gaoming!”

The village party secretary looked bitter, “I… hey, don’t be like this, you…”

Xu Junshan didn’t want to get entangled anymore, so he said to him: “Please! Village Party Secretary! Please come back! My family Xu Cong is a high school student, and we still have to study! Study is important, study is important.”

Don’t give any face, just walk away!

“I… hey…” The village party secretary felt regretful at this moment.

Xu Junshan breathed a sigh of relief after watching the village party secretary walk away, and looked at Zhou Xiuyun. Zhou Xiuyun gave Xu Junshan a thumbs up, “Good job!”

“That’s! For the sake of my son, I can still afford it!”

These two are very protective!

The two went back to the house, and now their opinions are very unified, that is, Xu Cong is the main one!

“Don’t disturb them studying, don’t watch TV! Go back to the house!”

Xu Junshan was warned as soon as he wanted to watch TV, and then he had to say: “Good, good! Don’t look down.”

In the study, Lin Mengjiao looked at Xu Cong and asked, “What about this question, can you see if I did it right, and how do you think about it?”

topic:

Hyperbola C: What is the distance from the right focus of (x²/9)-(y²/4)=1 to its asymptote?

Lin Mengjiao’s problem-solving idea is to draw pictures and use points: F=(√3,0)

Then calculate the asymptote: y=±2/3x……

Very complicated, although the final answer was given, it was correct.

But Xu Cong saw some headaches. This step was too troublesome, so he said to Lin Mengjiao: “Yes, it’s right, but the steps are too complicated.”

“The distance from the focus to the asymptote is b, the square of b is 4, and b is 2, OK, the end…” Xu Cong gave his method.

Lin Mengjiao was dumbfounded at the audience, and interrupted him quickly and said, “Wait, wait, ask Dema to get it, how did you get it? Why is b squared is 4? And b is really 2, right. Woolen cloth!”

“Then the following question can also be done?”

“The distance from the focal point of the hyperbola x²-(y²/2)=1 to the asymptote is 2 under the root sign? So simple?”

After Xu Cong glanced at the topic, he nodded to her with satisfaction, but now Xu Cong cares about nothing else, he cares about…

“Hey-hey….”

Xu Cong smirked, and said to her: “Are you going to have anything other than the ball?”

Lin Mengjiao was immersed in the question and didn’t hear what he was saying, so she asked stupidly: “What?”

She didn’t react to her, she was taken aback for a while!

Xu Cong didn’t say anything, still smirking, and soon the topic of the two people returned to the topic again.

Lin Mengjiao asked on a whim: “Xu Cong, how fast are you doing the questions? It’s the math exam papers. How fast can you do it?”

“Fill in the blanks, according to what you said, can be completed in three minutes, right?”

Xu Cong waved his hand and said dismissively, “Three minutes? Three minutes is too much!”

Three minutes is too much? ? ?

Lin Mengjiao is numb!

“Don’t let your big talk flash your tongue, although you answer the questions very quickly, but the college entrance examination paper is very difficult!”

Xu Cong narrowed his eyes and asked her, “Make a bet?”

Lin Mengjiao snorted and said bitterly, “Got it! I’m afraid of you! Humph! If you can finish it in three minutes, do what you want!”

“Okay! This is what you said!”

Xu Cong smiled, this smile was a little bit ill-intentioned.

“Find a question!”

Xu Cong hasn’t really calculated how long he can do the college entrance examination papers, but it won’t be too long!

Lin Mengjiao went to prepare, found some papers for the college entrance examination, put together four fill-in-the-blank questions that seemed to her to be difficult, copied them down, and handed them to Xu Cong.

The moment Xu Cong was reading the question, Lin Mengjiao timed it.

Topic 1:

If x and y meet the constraints 2x+y-2≤0, x-y≥0; y+1≥0, what is the maximum value of Z=x+7y?

Topic 2:

Let a and b be unit vectors, then |a+b|=1, then how much |a-b|=?

Topic 3:

Given that F is the hyperbolic C; (x²/a²)-(y²/b²)=1 (a≠0, b≠0) the right focus, A is the right vertex of C, B is the point on C, and BF Perpendicular to the x-axis, if the slope of AB is 3, what is the eccentricity of c?

Topic 4:

As shown in the figure, in the plane expansion diagram of the triangular pyramid P-ABC, AC=1, AB=AD=3 under the root sign, Ab is perpendicular to AC, AB is perpendicular to AD, ∠CAE=30, what is cos∠FCB?

We all know that Xu Cong is great, and we all know that Xu Cong handed in papers in advance, and we all know that Xu Cong’s questions are full marks!

But very few people have seen the Xu Cong exam with their own eyes, except for the invigilator!

Lin Mengjiao is also very curious about how Xu Cong answers the question. Moreover, this is a fill-in-the-blank question for the college entrance examination, and there is still a certain difference from the second year math test paper.

There are graphics in the third and fourth questions! Just looking at the pictures is very complicated!

“It’s already started! Xu Cong!” She said softly.

She looked at Xu Cong and thought to herself that it is impossible to complete each question in less than a minute.

Xu Cong ignored Lin Mengjiao. His goal is not 3 minutes! But shorter, less time!

After reading the first question, a few seconds later, Xu Cong wrote the answer 1!

The second question: √3!

Question 3: 2!

Fourth question: -1/4!

End the battle!

Xu Cong put down the pen and looked at Lin Mengjiao calmly, “How long?”
