下册第二章第10课二次函数的应用——最值问题-北师大版九年级数学全一册课件

当31≤x≤50时,W= x2+160x+1 850
(1)日销售量y(袋)与销售价x(元)的函数关系式;
(2)求当x为多少时,y有最小值,
(2)假设后续销售情况与试销阶段效果相同,要使
销售这种土特产每日的利润最大,每袋的销售
价应定为多少元?最大利润是多少元?
(2)依题意,设利润为W元, 得W=(x-10)(-x+40)=-x2+50x-400, 整理,得W=-(x-25)2+225. 当x=25时,W取得最大值,最大值为225. 故要使销售这种土特产每日的利润最大,每袋的 销售价应定为25元,最大利润是225元.
三级检测练
5 一级基础巩固练 8. 如图,用一段长为40 m的篱笆围成一边靠墙的草坪,
墙长16 m,当矩形的长BC为多少时,草坪面积最大? 最大面积为多少?
解:设AB=x m,则BC=(40-2x)m(12≤x<20), 面积为S m2. 根据题意得,S=x(40-2x)=-2x2+40x =-2(x-10)2+200, 因此当x=12,即AB=12 m,BC=16 m时,矩形草坪的 面积最大,最大面积为16×12=192(m2).
(2)依题意,得W=(y-18)·m.
故日销售量y(袋)与销售价x(元)的 (1)日销售量y(袋)与销售价x(元)的函数关系式;
由题意列得,a+2b=80,2a+3b=135.
函数关系式为y=-x+40. 根据题意得,S=x(40-2x)=-2x2+40x

<0,∴当x=32时,W取最大值,
(1)确定k,b的值;
解:设AB=CD=x m,则AD=BC= (12-2x) m(0<x<6). 这个花园的面积是S=x(12-2x) =-2x2+12x=-2(x-3)2+18. 当x =3时,S取得最大值, 此时S=18. 即这个花园的最大面积为18 m2.

Lesson10 Period2精品教案课题名称:Unit 4 Lesson 10 Problem Page 课型:Writing after reading教材版本:北师大版教师姓名:学校:授课年级:初二教学指导思想《英语课程标准2011版》明确指出义务教育阶段英语课程的总目标是:通过英语学习使学生形成初步的综合语言运用能力,促进心智发展,提高综合人文素养。

英语课程提倡采用既强调语言学习过程又有利于提高学生学习成效的语言教学途径和方法,尽可能多地为学生创造在真实语境中运用语言的机会。

综合语言运用能力的形成应根据初中生认知能力发展的特点和学业发展的需求,在进一步发展学生综合语言运用能力的基础上,着重提高学生用英语获取信息、处理信息、分析问题和解决问题的能力,形成健全的情感、态度、价值观。

在语言技能目标(五级)中对写作技能的目标要求学生能根据写作要求,收集、准备素材;能独立起草短文、短信等,并在教师的指导下进行修改;能使用常见的连接词表示顺序和逻辑关系;能简单描述人物或事件;能根据所给图示或表格写出简单的段落或操作说明。

在情感态度目标(五级)中要求学生能在英语交流中注意并理解他人的情感以及积极与他人合作,相互帮助,共同完成学习任务。

at an age when financial mistakes are not very costly.The amount of money that parents give to their children to spend as they wish differs from family to family.Timing is another consideration.Some children get a weekly allowance.Others get a monthly allowance.In any case, parents should make clear what, if anything, the child is expected to pay for with the money.At first, young children may spend all of their allowance soon after they receive it.If they do this, they will learn the hard way that spending must be done within a budget.Parents are usually advised not to offer more money until the next allowance.The object is to show young people that a budget demands choices between spending and saving.Older children may be responsible enough to save money for larger costs, like clothing or electronics.Many people who have written on the subject of allowances say it is not a good idea to pay your child for work around the home.These jobs are a normal part of family life.Paying children to do extra work around the house,however, can be useful.It can even provide an understanding of how a business works.Allowances give children a chance to experience the three things they can do with money.They can share it in the form of gifts or giving it to a good cause.They can spend it by buying things they want.Or they can save it.1.What is special about children

the kids?1.________ Public school teacher and blogger Chelly Wood believes that “it's important for kids to get at least one hour of playtime after school, regardless of age.That's ‘real’ playtime,

What's worse, they sometime quarrel with others, and even turn a deaf ear to their parents and teachers, which is very disappointed. In my opinion, we middle school students should make our efforts to improve the situation. First, we should respect the others. Second, when we are not feeling well, we can chat with us friends or teachers or even parents. It was likely that they can understand us better and give us some reasonable advices.答案:Ⅰ.1.out 2.behaviour 3.that 4.amusement 5.importance 6.balanced7.appealing 8.enthusiastic9.economic10.annoyingⅡ.1.if not 2.not until; that 3.is of great importance 4.that he had doneⅢ.1.makes a living 2.for a start 3.took turns to 4.appeal to your market 5.started/began with 6.agree with7.What's moreⅣ.1.buying 2.instead 3.approximately 4.have been removed 5.which/that 6.to solve 7.in8.importance9.crops10.to developⅤ.语篇解读:本文主要介绍了如何教育孩子学会理财。
