M51，V和总分就不光彩了，所以大半夜还是贡献点数学

１.x和y 都是positive integrate，　问y是不是３的倍数？

（１）Y=2X^3+9X^2-5X

（２）X是３的倍数

我选A．刚开始是考虑C, 但之后发现（１）里有trap，因式分解后有三个factor相乘，分别是x除３余０，１，２的情况，因此y能被３整除

２．一广告商一年做２个商业广告，每个３０秒／小时，且每天都在４个小时的时段中播出（就是每天每个广告时间一共１２０s，我是这么理解的，希望有谁核实下），该广告商一年收入＄４０million，问一个广告每minute的价格

我选答案A. $27,000．这题楞了半天，就是红色部分不确定．

３．一store一星期工卖了１０台冰箱，问每天销售量的中数

（１）每天都至少卖了一台

（２）每天最多卖２台

我选D

４．坐标系内，一圆的面积是１，问下面哪两个点可能同时在该圆上？

记得我选的是E．通过面积求得直径D^2约＝1.24左右．只有最后一对的距离的平方小于这数．这题就是计算麻烦，牵涉到pai的开方，或者比较平方．

明天想起什么在补充．希望给后人造福

AI:

“Too many people think only about getting results. The key to success, however, is to focus on the specific task at hand and not to worry about results.” 我就练了两篇，这也能撞到，窃喜，不过AI就死的很难看了．

AA:

Throughout the last two decades, those who earned graduate degrees found it very difficult to get jobs teaching their academic specialties at the college level. Those with graduate degrees from Waymarsh University had an especially hard time finding such jobs. But better times are coming in the next decade for all academic job seekers, including those from Waymarsh. Demographic trends indicate that an increasing number of people will be reaching college age over the next ten years; consequently, we can expect that the job market will improve dramatically for people seeking college-level teaching positions in their fields

AA是先考的，不过最后一句话没写完，而且正文第二点论述基本上只是模版，内容充实不多，只有两三句话．请NN 们给说说我的作文得分会有多惨？
