用乘法分配率
如果是2011×2009+1
=(2010+1)×(2010-1)+1
=2010²-1+1

|采纳率85.7%(1)现在每件衬衫平均每天盈利40/20=2元,设降价x元,则有(20+2x)(2-x)=1200,此题无解.
(2)每天盈利额为(20+2x)(2-x),也就是求函数y=(20+2x)(2-x),当X取什么值时,y取最大值.函数的图像是个顶点朝上的抛物线,所以当X=-4元,即再涨4元时,可以得最大值y=72元.
怪异的题目,怪异的结果----不会是每件每天盈利40元吧?!那样的话答案就是(1)10元或20元;(2)降价15元,每天盈利最大,1250元.1年前查看全部

一种元素一定数目的原子跟其他元素一定数目的原子化合的性质,叫做这种元素的化合价.
化合价之二
化合价是体现了元素间形成化合物时彼此间数值关系的一种性质.
一种元素一定数目的原子跟其他元素一定数目的原子化合的性质,叫做这种元素的化合价.
化合价用数值表示,有正价、负价.在单质中元素化合价为零.
化合价之三
化合价是表示一种元素的一个原子能和其他原子相结合的数目.化合价有正、负之分.在离子化合物里,元素化合价的数值,可视为该元素原子所成离子的电荷数.在共价化合物里,元素化合价的数值,常为该元素的一个原子跟其他元素的原子形成的共用电子对的数目;化合价的正负决定于共用电子对的偏向或偏离,共用电子对偏离的原子为正价,偏向的原子为负价.不论是离子化合物还是共价化合物,正负化合价的代数和都等于零.化合价与化学键有密切联系,一般地说化合价表示各原子间化学键的数量关系.根据化学键的类型,化合价分为电价和共价,电价是离子价,共价是共价键所代表的化合价.元素的化合价在不同化合物里的数值不同,具有变价,如锰有+2、+4、+6、+7多种化合价.1年前查看全部

|采纳率100%Gothic culture and the Gothic rock / metal music what "Gothic"? First, literally interpreted, it embraces the three significance, the first in the Gothic architectural style as Cathedral (cathedral), the biggest feature is the tall arched ceilings and structural beams and Tsim Sha Tsui; Second, in Gothic literature is used to describe those dark lonely places (such as abandoned Castle) to the background of a strange mystery adventure story; Third, also on behalf of a Gothic font and vocals of printing and writing style. The earliest "Gothic" this characters is based on the Renaissance period was used to distinguish the Middle Ages (Middle Ages,5~15 century) art style its the Exaggerative is from in had the Y2K 3 ~ 5 century aggression Italy and the dismantlement of the Roman Empire the German Gothic tribe, in the 15th century, Italy person with the revitalization of in ancient Rome culture of idea of thus whip up the splendid literature and movement, as Italy person to Gothic nation to destroy the Roman Empire during this period of history two lovers whose source is always difficult to-plussed when, therefore of order in connection with this period to targeting a specific audience sector, they will cast the Middle Ages the arts style titles for Gothic, as they were concerned means that the barbaric. Despite the original Gothic is the word carries with it a negative connotation, but in fact impressive and beautiful works of art have been created out at this time. 12 century, the construction of sophisticated technology, thus creating a lot of the birth of Gothic cathedral, it is the most famous Notre Dame Cathedral in Paris (Notre Dame). Of course, the Gothic style was not limited to construction, such as sculpture, glassware, jewelry and colorful tie is responsible and so on, are affected by such art from the 12th century to the early 16th century has ended. Gothic art in fact religion plays a very important role, regardless of the artist or sculptor, in that they would prefer to work on religious issues, themes and less interested in realism. About in the Year in 1800 around the latest arrival Romantic Movement (Romantic Movement), Gothic with the medieval culture is again being people's pro-have altered history textbooks to mislead the ideology able to to recover and Romanticism can be said to be For the Enlightenment Movement (the Enlightenment) rationalism (Rationalism) reactionary, perceptual, non-rational attitude is this the campaign centers in this period, Gothic started and darkness, singular, weird found in relation to, in fact grand romantic style the are many symbolic and subject matter and these Gothic the sub-culture of a rather similar, this period of some writers very keen on Description people's darkness, emptiness face, sexual paranoia, terror, a god themes are literary works were widely to use. In addition, in the visual arts, Romantic painters prefer the same dark, desolate landscape. In a symbol of Gothic novels is the most typical vampire (vampire), the works of Bram Stoker's classic "Dracula", and even joined the Vampire images in the book, for the development of the 19th century Gothic literature is entitled to the origins of vampires.
Time came to the 1980s, new Gothic movement started in Britain did the Gothic movement there might be considered on the previous Cyberpunk culture (Punk), a reactionary, no matter how, Gothic spirit started in music to demonstrate its influence, Gothic music the same preferences to encourage the darkness and emptiness face as a title, and of death also has a strong interest, the slow, sad and even terror are its music features, and vampires again become the theme of the best symbol. In addition to the musical performance of the Columbia mission groups in the visual artists showing dead aesthetics, such as a pale face painting, black clothes, or the British Zhebian 19th century Victorian-style clothing, and the ruins of medieval, Gothic-style buildings have been extensively applied. Gothic movement in the United Kingdom reached a peak in the mid-1980s, and most representative of the Orchestra of The Sisters of Mercy, The Mission and other Fields of the Nephilim. Musical styles, the music of this period was known as the British New Wave Gothic, adding in a lot of rock synthesizer (keyboard), and the above mentioned Gothic elements, even with electronic flavor. Wave and Gothic rock/New imported in the United States in the further development of industrial branches, known organizations such as Ministry and Nine Inch Nail; The other hand, Europe is even more flooding to electronic music. Although Gothic music in Europe towards more electronic music, but also a number of other deformation, but in fact Gothic metal music is brewing in the early 1990s, and finally in 1995 by the Norwegian Theater of Tragedy regiment's first album 80 of the same name metal era of Gothic atmosphere. But at the beginning of talks Gothic metal ago, we had to start with the destruction of metal (doom metal) came, doom metal is a very heavy, dark, slow, melancholy and sadness in the music form that was doom metal earliest origins can be traced to Black Sabbath's first album the same name, and the subsequent album, but really doom metal style set is from Sweden regiment Candlemass in 1986 published the album began. A lot of doom metal group in the late 1980s to the early 1990s when the birth of the famous British regiment My Dying Bride then more will be included in the preparation of the violin as a bleak future reference Orchestra sent doom metal pioneer.
And doom metal in the 1990s, many have begun the development of Theater of Tragedy is the first to doom metal and gothic rock from the inspired fusion of the gothic and then create a new school doom metal and T.O.T. Can be said to be a rejuvenation of the most important Gothic style hero once again, T.O.T. Gothic metal makes this wave of success from the Nordic spread quickly from the beginning. Theater of Tragedy several characteristics have become Thereafter Columbia mission metal basic elements, in particular, has become today the mainstream style of gothic death, such as mining death metal brutal men cavity (or even black metal Tsim roar black cavity) match Sophie beautiful women sounded the antiphonal singing form, it is precisely Israel romantic Gothic spirit of this contrast style but also a symbol of darkness (dead space and metal Le part) with a bright future, life and love (female sounded, piano and symphonic part) between confrontation. And T.O.T. Soprano lead singer Liv arms and the beauty of her singing did not know how much steel already conquered the hearts of men. But European countries because of cultural differences, making gothic metal is also developing even spread out in many different forms, apart from gothic doom, in the Netherlands from The Gathering has established himself as a gifted beautiful women sounded as lead singer and focus on spiritual feeling, the pure gothic metal, its lead singer Anneke van Giersbergen unsubstantial and muddied U.S. tone can be described as gothic metal sector perfect example later, in the other two the Dutch gothic metal Mission Within Temptation and After Forever, have to have timbre approximate Anneke of the nest and singing a saying, The Gathering of Dutch gothic metal shows the influence. The Gathering is a gradual change in the near future, however style metallic components has become increasingly short. In addition, the Nordic Orchestra further to be some black metal with elements of gothic Among become gothic black and renowned orchestras have the same from the Norwegian Tristania and The Sins Of Thy Beloved, etc. However, in fact, gothic in the Nordic development has been to gothic, doom, death, black integrated, and so difficult to categorize in a single style, such as Tristania Apart from the grand symphonic stature, or even using clean men cavity, black dead space plus opera female lead singer and choir chorus. Of course, the Nordic Music Orchestra has not only was it thought Sweden Therion will be to develop a distinctive orchestral instruments (synthesizer sound samples) and metal instruments of both symphonic opera metal, in its most recent concert are completely Opera Choir and professional men and women. In addition, Finland As Divine Grace Chen Jing elegant atmosphere gothic to go through the ups and prosperous world feel. Germany were developed in classical gothic folk kingdom come, Lacrimosa, Haggard, in addition to these groups synthesizer, but also for the actual music, classical flavor is very strong, as Lacrimosa directly with the London Symphony and the Orchestra includes members of Haggard's hand or even 18. Italian avant-garde in recent years to speed metal and symphonic metal gained bombs in the whole of Europe, but its Gothic metal in the development of not falling behind, Inner Shrine, the argument is a prime example, the former U.S. sorrow desolate atmosphere, which is filled with romantic and charming melodies. In addition, there are also some focus on the atmosphere created by the orchestra, filled with a sense of medieval Dunwich and Crown of Autumn, which Dunwich more use of musical instruments and medieval monks choir. Other European countries also have representation of the orchestra, such as Poland, Sirrah, the Even Song Hungary, Romania On Thorns I Lay, style are completely different. From the above introduced can understand, the Columbian the Independent Commission on the metal Lok has been a comprehensive development no longer confined to a single style, while Gothic is not just a rock, it is most of all a life attitude, Gothic is one which people can to flee reality and enter the illusion the world, a dark and romantic the world, Gothic the spirit of not only can manifested in music, can also in their attire artistically and literature, with a great number of lace. The clothes, symbol of a romantic Rose, graves, are connected with vampires, witches, ruins, Gothic's Cathedral so on, have all these are Gothic of symbols. Of course, purely from a musical point of view, the general preference of the strong metal fans directly, it may slow, focused atmosphere of Gothic metal play more difficult to accept, but if it gets to the root of this music to understand the background and send their wish has moods, appropriately adjust your own mind, he may realize that a different type of feeling and fun to listen to.1年前查看全部

|采纳率95.2%解题思路:(1)不同物质能够彼此进入对方,物理学把这类现象叫做扩散;扩散现象并不是外界作用引起的,而是由物质分子的无规则运动产生的.在扩散运动中我们会发现,温度越高,扩散的越快;
(2)电动机工作时,把电能转化为机械能;
(3)并联电路中,各用电器互不影响.答:(1)在炒辣椒时,辣椒中的辣味分子受热,运动加剧,扩散现象加快,所以辣椒中的辣味分子很快扩散到整个房间内,辣味分子对人有刺激作用,因此卧室里的小明也会被呛的眼泪直流;
(2)电风扇在工作时,消耗电能,产生了机械能,故是将电能转化为机械能的装置;
(3)电扇与其他家用电器之间是并联的,各家用电器并联时,用电器能正常工作,并且互不影响.点评:
本题考点: 分子的热运动;能量的相互转化;家庭电路的连接.
考点点评: 本题考查的知识点较多,属于综合题.1年前查看全部

|采纳率82.4%造物主创造了生命,使得世间有了活力.生命在历史的长河中繁衍,绽放了绚丽夺目的光彩.生命自产生起就是为了精彩而存在.
塞内卡说过:“生命如同寓言,其价值不在长短,而在内容.”生命只有焕发光彩,方不辱没生命的意义.
历史长河中,无数英烈为了使生命变得精彩而做出了生与死的抉择.屈原为了使自己的生命变得精彩投入了泪罗江中;一代大侠荆轲,为了生命的精彩,高吟着“风萧萧兮易水寒,壮士一去兮不复还”而血洒咸阳殿;以“人生自古谁无死,留取丹心照汗清”千古绝唱而流芳百世的文天祥,为了生命的精彩躺倒在蒙古人的大刀之下;“一腔碧血勤珍重”的鉴湖女使秋瑾为了生命的精彩,命丧清狗之刀下.无数的英雄儿女,不甘平凡,舍生取义,使生命绽放出耀眼的光芒.
生命需要精彩,精彩燃烧出生命的辉煌.
巴斯德说:“生命在最危险的环境中,方是真正的生命”.小草生长在瓦砾之中,才显出它生命的精彩;苍松矗立于绝壁之上,才显出它生命的精彩;骆驼奔走于沙漠之中,才显出它生命的精彩.只有精彩的生命才能在宇宙之中永生不灭.
生命有意义才会精彩,精彩的生命才会有意义.
凡高的一生融入了向日葵,把艺术的精华留给了人类,他的生命是精彩的;贝多芬的一生奉献给了音乐,用生命之曲唤醒人类,他的生命也是精彩的;马克思把他的一生奉献给了共产主义事业,他的生命也是精彩的;孔繁森把他的一生奉献给了兰考人民,他的生命同样是精彩的……巴金说过:“寒冷寂寞的生,不如轰轰烈烈的死.生命如果没有意义,那么尽早就结束它”.
小草把绿色献给春天,使它的生命变得精彩;清泉,把它的甘醇流淌入干渴者的心田,使它的生命变得精彩;红日,把它的温暖传递到严寒的隆冬,使它的生命变得精彩.
花开不是为了凋谢,而是为了结果,结果也不是为了终结,而是为了更生.生命亦是如此!1年前查看全部

|采纳率100%解题思路:把苹果的进价看作单位“1”,按30%的利润定价,卖出60%后,他的收入为(1+30%)×80%,剩下的全部打对折出售,则收入为(1+30%)×(1-80%)×50%,总收入为:(1+30%)×80%+(1+30%)×(1-80%)×50%;求出后减去1,即可.80%×(1+30%)+(1-80%)×(1+30%)×50%-1,
=1.04+0.13-1,
=0.17,
=17%;
答:商店售完后实际获得利润的百分数是17%.点评:
本题考点: 利润和利息问题;百分率应用题.
考点点评: 此题属于易错题,解答此题的关键是判断出单位“1”,根据一个数乘分数的意义,用乘法分别计算出早先出售的总价和后来出售的总价,进而根据题意,减去苹果的进价解答即可.1年前查看全部
