设[x]表示不超过x 的整数中最大的整数.如[1.97]=1,[-1.35]= -2,根据规律计算:[-6.2]-[一又二分之一] 设[x]表示不超过x 的整数中最大的整数.如[1.97]=1,[-1.35]= -2,根据规律计算:(1)[2.9]-[-3] 设[x]表示不超过数x的整数中最大的整数,例如:[2.53]=2,[-1.3]=-2,根据此规定做下列运算：1 [5.3]+[3] 2 [-4.3]+[2/3] 3 [5/3]-[-1又2/1] 4 [0]+[-2.7] 曲线C与抛物线y^=1/2 x 关于直线y=x对称,求曲线C的方程?抛物线y^=2x上各点与焦点连线中点的轨迹方程? He doesn't know where he can do.(同义句）He doesn't know where _____ _____ _____where he can go。 已知点H(-3,0),点P在y轴上,点Q在x轴的正半轴上,点M在直线PQ上,且满足向量HP乘以向量PM等于0,向量PM等于-3/2向量MQ.（1）当点P在y轴上移动时,求点M的轨迹C的方程.（2）过T（-1,0)作直线与轨迹C交于A 改错：He doesn's know where can he go. 求 如图所示 希望用弦长定理、点到直线距离求解 其它方法的绕行吧 希望用弦长定理、点到直线距离求解 其它方法的绕行吧 希望用弦长定理、点到直线距离求解 其它方法的绕行吧 希望用弦长定理 1：Were you interested in them?（变陈述句） 2：I went to a moved yesterday.（变成否定句） you,in,them,interested,were连词组句 设y=[x/(12+1/2)]·[-(12+1/2)/x]其中[x]为不超过x的最大整数,若0 设［x］表示不超过x的整数中最大的整数,如［1.97］=1,［-1.35］=-2,根据此规律计算:（1）［2.9］-［-2.9］；（2）［-6.2］-［1又2/1］. 设【x】表示不超过x的整数中最大的整数,如:【1.99】=1,【-1.02】=-2根据此规律计设【x】表示不超过x的整数中最大的整数,如：【1.99】=1,【-1.02】=-2根据此规律计算 （1）【-0.6】= （2）【2】= （ 设【X】表示不超过X的整数,如【1.99】=1,【-1.02】=-1,根据此规律计算（是什么意思） he doesn't knowA.what does the boy like B.what the boy does like C.what the boy like D.what the boy likes Where are you going this afternoon 答句 他不知道乘哪辆车英语 He doesn”t know （ ） （ ） （ ） He doesn't know ___(该做什么). 判断对错.there is a bike in the picture All the students were very interested in the film.All the students ___ great ___in the film.
