同理:n=(4,一3,-2),…..….13分所以点M的坐标为(4k²-12k-3312k²+6km·n84k²+32.4k²+3设面AED与面ECD 的夹角为6,则cosθ=|cos0恒成立,f(x)在R上单调增;……2分当a>0时,令f(x)=0,解得x=lna,4k+34k²+3若x∈(-0o,lna),则f(x)<0,若x∈(1na,+oo),则f(x)>0,(i)设 P(xo,yo),直线 PM,PN的方程分别为y-y=k(x-xo),y-y=k(x(2)(i)由题意,g(x)=e²-x²-ax-l,g(x)=e-令h(x)=e-ax-a,则h'(x)=e²-a,当a≤0时,由(1)可知,h(x)在R上单调逆增,h(0)=1一a>0,所以g(x)=h(x)>0在(0,+∞∞)上恒成立,所以g(x)在(0,+∞o)上单调递增,所以g(x)>g(0)=0,成立,(合+2)20+(+1)-当01时,由(1)可知,h(x)在(0,lna)上单调递减,(1na,+oo)上单调递增,又h(0)=(各+2)所以Q点的坐标为2yo2(+1)2(+1)12分所以当xE(0,lna)时,g(x)<0,即g(x)在(0,lna)上单调逆减,故g(lna)x,要证x<2x,只要证g(x)0,.........14分所人LFP&=LFPQ.BPPQ分LFPF..x2+1即证e-2x-1>0恒成立.…1.5分yyo4yo<()()()(x)则tanF,PQ=x0+130x。-13xo份1+,tanF,PQ=16分第二节英语1+-y.y所以g(x)>0恒成立,故x<2x成立.17分One possible version:工+13x。Panicking,wecalldataxiandrushed to thenearesthospitaThride seemed totake(ii)详见解析forever,and he painin my legs grewmore intense with every passingminute,I tried to+Y=1(x≠±2);distractmyself by talking tomy friend,bat it was hard to focus on anything other than theburning pain.When we finally arrived at thehospital,Iwas helped intoa wheelchair and3分quickly taken to thecmergencyroom.Thedoctors examinedmylegs and toldmeIhad severe(2)(i)设直线 PM的斜率为k,M(,y),N(x,y).则直线 PM的方程为:y3=k(x-1),sunburn. They applied gentle creams and bandages to my legs and gave me medicine to helpwith the pain.与C联立方程组,消去y可得:3x²+4(kx+3=12After several hoursof treatment,Iwasadmitted to thehospital forfurtherobservation.The nurses were kind end checked on me regularly,making sureIwas as comfortable aspossibleIsent thenextfewdaysinthehospitlfeelingembarrassed anddpressedbecause2由于直线PM与C交于P,M两点,则由韦达定理可得:mycarelessnesshadled to sucha serious situationMyfrindsvisitdmebringinggiftandoffring theirsupport,butIcouldn'tshakethefling ofguilt.Itoldmyself thatwheneverk23_12k²+6kgooutsidhuldtouand tkttiveareshasinueex+1=,即x4k²+34k²+34k²+3wearing protective clothing,and staying in the shade when possible.2合【数学精准预测卷(一)·参考答寓第5页(共6页)】合2【数学络准预测物(一)·参老答客第6页(共6页)】
