(2)y1=x2-3x+1，y2=ax2+bx+c，

∴y1-y2=(1-a)x2-(3+b)x+1-c=(1-a)·.

又y1-y2与y1互为“对称二次函数”，y1=x2-3x+1=，

∴解得∴y2=2x2-6x+.∴y2=2，

∴y2的对称轴为直线x=，∵2>0，且-3≤x≤3，

∴当x=-3时，y2最大值=2×(-3)2-6×(-3)+.八．(本大题共14分)【考点】相似三角形的判定与性质、全等三角形的判定与性质、勾股定理、等腰直角三角形、正方形的性质以及图形旋转的性质【答案】(1)BD=CF成立.

∵△ABC是等腰直角三角形,四边形ADEF是正方形,

∴AB=AC,AD=AF,∠BAC=∠DAF=90°,

∵∠BAD=∠BAC-∠DAC,∠CAF=∠DAF-∠DAC,

∴∠BAD=∠CAF,∴△BAD≌△CAF.∴BD=CF.

(2)①设BG交AC于点M.

∵△BAD≌△CAF,∴∠ABM=∠GCM.∵∠BMA=∠CMG,∴△BMA∽△CMG.

∴∠BGC=∠BAC=90°,∴BD⊥CF.

②过点F作FN⊥AC于点N.∵在正方形ADEF中,AD=,

∴AN=FN=AE=1.在等腰直角△ABC中,AB=4,∴CN=AC-AN=3,

BC==4.

在Rt△FCN中,tan∠FCN=.

∴在Rt△ABM中,tan∠ABM==tan∠FCN=.∴AM=AB=.

∴CM=AC-AM=4-,BM=.

∵△BMA∽△CMG,∴.

∴,∴CG=.

在Rt△BGC中,BG=.扬州树人学校九年级第二次模拟考试英语试卷202105（试卷分值：120分考试时间：100分钟）一、单项选择（共15小题，每小题1分，共15分）在下列各题A、B、C、D四个选项中选择一个能填入题干空白处的最佳答案。1.Jane'sgrandmotherwantedtowritechildren’sbookformanyyears,butonethingoranotheralwaysgotinway.A.a;不填B.the;theC.不填;the D.a;the2．ofthemenwaschargedwithrobbery，butI’mnotsurewhichwas．A．NeitherB．EitherC．Both D.None3.—Youaren’tsupposedtosmokeinpublic.It’sbadforourhealth.—Sorry,Iwillmycigaretterightnow.A.giveup B.putdown C.putout D.giveaway4.Heusedto_____histimeontheInternetaftersupper,butnowhegetsusedto_____awalk.A.spend;taking B.spending;take C.spend;take D.spending;taking5.ATVseriesnamedIntheNameofPeople
