已知(ax²-bx+3)(2x³-3x+b)不含x²项且常数项为-3,求a、b的值 I will go where you go go的好多用法很奇怪 有go to somewhere go for a walk 似乎表示走时不及物但是这一句:I will go where you go如果把where you go理解成名词性从句 那么它就是go的宾语 可go是不及物动词啊 设公因式ax^3-5^2+bx+c/2x^3-10x^2+3x-4的值横为常数,求a、b、c的值及此代数式的值 Where will you go 这里怎么理解?where 是引出疑问句在句中担任,地点状语 应该是可以确认的.where will you go go 这里为什么不用 to,说法1是 go to where 副词where 前面不需要介词,2 观点是:go 是不及物动 如果考试题1,0,3,0.5,3/4这些数,让分数集合,那0.3算分数吗?如果让小数集合,那3/4算小数吗?我的数分类学的不好, 蒙娜丽莎的创作背景是 什么 蒙娜丽莎背景里的动物有什么 北师大版六年级上册数学第四单元测试题(第一套) 一.填空题:1.5÷8= (分数)=( ):( )=( )小数北师大版六年级上册数学第四单元测试题(第一套)一.填空题:1.5÷8= (分数)=( vb中读取文本数据文件时,想对文本中的数据赋给新的变量.其中的2,3只是作为判断用,下面的数据是需操作的2 100,200 200,300 2 50,100 100,200 3100,300 200,400150,250 函数y=log2[(a²-1)x²+(a-1)x+1]的定义域为R,则a的取值范围是函数y=log2[(a²-1)x²+(a-1)x+1]的值域为R,则a的取值范围是 when i call you this morning,nobody answer the phone. where____? 答案填were you,为什么...when i call you this morning,nobody answer the phone. where____? 答案填were you,为什么不可以写did you go.? No one answered when I phoned this morning.Where were you?—I for teeth in the dental clinicA.was being treated B.have been treated C.was treated D.treated解释为什么选A Where were you this time yesterday morning?I just stayed home and __TV at thA:wacth B:was wacthing c:had wacthed Where were you this time yesterday morning?I just stayed home and __TV at the moment.A:wacthed B:was wacthing 已知定义域为0到正无穷的函数f(x),同时满足条件:f(2)=1,f(6)=4,f(xy)=f(x)+f(y),求f(3)和f(9 二项式定理过程我插呀 题目没错啊 是你能力有问题吧?! 有关二项式定理(1-3a+2b)^5展开式中不含b的项的系数之和是多少?请问为什么可以把b令成0,再把a令成1,然后得到-32, 二项式定理是什么 Where were you when I was burned and broken?Where were you when Iwas hopeless?Because the things you say and the tings you do surround me.I was staright into the shinning sun,lost in throught and lost in time.中文翻译. 英语翻译十万火急! Where were you when I was burned and broken?Where were you when I was hopele (—0.25)+(—3)—负1又4分之3的绝对值—(—3) 化简(二项式定理):(1+√x)^5+(1-√x)^5 如何用二项式定理推算(x+(1/x)-1)^5的展开式? 3(x-1)²-18=0 二项式定理:(1-根号x)^6*(1+根号x)^4展开式中x的系数是?^指的是平方 若多项式的值与字母x的取值无关求ab的值 已知两个集合A,B是全集U的两个子集合,用维恩图说明集合A交CuB与集合B交CuA的交集是空集最好有图,不画的话把意思说明白也行, 关于二项式定理的.C10取9 + C11取9 + C12取9 + ...+ C19取9 = 结果是C20取10 -1吧还是+1怎么算的?把步骤写下来, 高中必修2数学解析几何复习题2的答案 设全集I={x|1≤x<9,x属于N},求满足{1,3,5,7,8}与B的补集的集合为{1,3,5,7}的所有集合B的个数 多项式与多项式的差与其中的几个字母因数的取值无关是什么意思?
