第3讲二次函数的实际问题--尖子班

第3讲二次函数的实际问题知识点1二次函数的实际问题之利润问题1.利润、售价、进价之间的关系：利润=售价-进价。

2.总利润、单价利润、数量之间的关系：总利润=单件利润×数量。

【典例】【题干】某农产品市场经销一种销售成本为40元的水产品．据市场分析，若按每千克50元销售，一个月能售出500千克；销售单价每涨一元，月销售量就减少10千克．设销售单价为每千克x元，月销售利润为y元，则y与x的函数关系式为（）A. y=（x﹣40）（500﹣10x）B. y=（x﹣40）（10x﹣500）C. y=（x﹣40）[500﹣10（x﹣50）]D. y=（x﹣40）[500﹣10（50﹣x）]【答案】C.【解析】解：设销售单价为每千克x元，月销售利润为y元，则y与x的函数关系式为：y=（x﹣40）[500﹣10（x﹣50）]．故选：C．2.某公司销售一种新型节能电子小产品，现准备从国内和国外两种销售方案中选择一种进行销售：①若只在国内销售，销售价格y（元/件）与月销量x（件）的函数关系式为y=﹣x+150，成本为20元/件，月利润为W内（元）；②若只在国外销售，销售价格为150元/件，受各种不确定因素影响，成本为a元/件（a为常数，10≤a≤40），当月销量为x（件）时，每月还需缴纳x2元的附加费，月利润为W外（元）．（1）若只在国内销售，当x=1000（件）时，y=（元/件）；（2）分别求出W内、W外与x间的函数关系式（不必写x的取值范围）；（3）若在国外销售月利润的最大值与在国内销售月利润的最大值相同，求a的值．【解析】解：（1）当x=1000时，y=﹣×1000+150=140，故答案为：140．（2）W内=（y﹣20）x=（﹣x+150﹣20）x=﹣x2+130x．W外=（150﹣a）x﹣x2=﹣x2+（150﹣a）x．（3）由题意得（750﹣5a）2=422500．解得a=280或a=20．经检验，a=280不合题意，舍去，∴a=20．【方法总结】解这类题方法是：（1）设y=kx+b，把点的坐标代入解析式，求出k、b的值，即可得出函数解析式；（2）根据利润=（售价﹣进价）×销售量，列出函数关系式,把二次函数化成顶点式来求题目中的最大值。

I saw someone wearing it on the underground today. It feels like they might be able to transmit WI-FI signals.'But street vendors are glad of the trend.

(三) 宾语从句的时态
1.若主句为现在时态,从句的谓语动词可根据具体情况选用所需要的时态。 ♦We hope you’ll have a very happy year in our class.我们希望你在我们班能度过快乐、幸福的一年。 2.若主句为过去时态,则宾语从句通常选用过去时态中的某一种形式。 ♦He said he was doing his homework then.他说他那时在做作业。 3.若从句是客观真理、一种现象、科学原理、现阶段存在的客观事实、经常性、习惯性动作,或是谚语、格言等,其时态常用一般现在时。 ♦The scientists said the sun rises in the east and goes down in the west. 科学家们说太阳从东方升起,西方落下。
(六) 宾语从句与简单句的相互转换
当宾语从句是由when,where,why,who,which,what,whose等引导时,有时可以转换为由“疑问代词/疑问副词+不定式”结构作宾语的形式,从而句子便由一个主从复合句变为了简单句。
1.当主句的主语与宾语从句的主语一致时,可以将其改为简单句。 ♦I don’t know what I shall do next. =I don’t know what to do next.我不知道下一步做什么。 2.当主句中含有双宾语时,如果间接宾语与宾语从句的主语一致时, 也可以将这个主从复合句变为简单句。 ♦Can you tell me how I can get to the police station? =Can you tell me how to get to the police station?你能告诉我怎样到达警察局吗?
