＝﹣2（x﹣1+2）2+3．故得到抛物线的解析式为y＝﹣2（x+1）2+3．故答案为：y＝﹣2（x+1）2+3．16．【解答】解：设这两次的百分率是x，根据题意列方程得100×（1﹣x）2＝81，解得x1＝0.1＝10%，x2＝1.9（不符合题意，舍去）．答：这两次的百分率是10%．故答案为：10%．17．【解答】解：如图，作点D关于直线AB的对称点H，连接CH与AB的交点为E，此时△CDE的周长最小．∵D（，0），A（3，0），∴H（，0），∴直线CH解析式为y＝﹣x+4，∴x＝3时，y＝，∴点E坐标（3，），故答案为：（3，）．18．【解答】解：∵四边形ABCD是菱形，∴AB＝5，AC⊥BD，AC＝2AO，BD＝2BO，∴∠AOB＝90°，∴AO2+BO2＝AB2＝52＝25，∵对角线AC，BD的长度分别是一元二次方程x2﹣2（m+1）x+8m＝0的两实数根，∴2AO+2BO＝2（m+1），2AO•2BO＝8m，∴AO+BO＝m+1，AO•BO＝2m，∴AO2+BO2＝（AO+BO）2﹣2AO×BO＝25，∴（m+1）2﹣4m＝25，解得：m1＝6，m2＝﹣4，∴当m＝﹣4时，AO•BO＝﹣8＜0，不符合题意，舍去，即m＝6，则AO•BO＝12，AC•BD＝2AO•2BO＝4AO•BO＝48，∵DH是AB边上的高，∴S＝AB•DH＝AC•BD，菱形ABCD∴5DH＝，∴DH＝．故答案为：．三、解答题（本大题共8个小题）19．【解答】解：（1）原式＝2﹣1+4+﹣2＝3+1；（2）∵2x2+4x﹣1＝0，∴x2+2x＝，∴x2+2x+1＝+1，即（x+1）2＝，∴x+1＝±，所以x1＝﹣1+，x2＝﹣1﹣．20．【解答】解：原式＝÷＝•＝，∵a2﹣2a＝0，∴a1＝0，a2＝2，而a＝0时，原式没有意义，∴a的值为2，当a＝2时，原式＝＝．21．【解答】解：（1）a＝1﹣20%﹣10%﹣15%﹣30%＝25%，本次抽测的人数为：60÷30%＝200，则测试成绩为6个的学生有：200×25%＝50（人），补全的条形统计图如右图所示；（2）在这次抽测中，测试成绩的众数是5个，中位数是5个；（3）600×（25%+20%）＝600×45%＝270（人），即两校体育中考中选报引体向上的男生能获得14分及以上的有270人．22．【解答】（1）证明：∵点E是边AC的中点，∴AE＝EC．又∵EF＝DE，∴四边形ADCF是平行四边形．又∵点D、E分别是边AB、AC的中点，∴DE是△ABC的中位线，∴DE∥BC．又∵∠ACB＝90°，∴∠AED＝90°．∴AC⊥DF．∴四边形ADCF是菱形．（2）解：∵四边形ADCF是菱形，∴CD＝CF＝AF＝AD，在Rt△ABC中，AB＝＝＝2，∵D是AB的中点，∴AD＝AB＝，∴四边形ADCF的周长＝4．23．【解答】解：（1）依题意，得：y＝600﹣10（x﹣40）＝﹣10x+1000．（2）依题意，得：（x﹣30）（﹣10x+1000）＝10000，整理，得：x2﹣130x+4000＝0，解得：x1＝50，x2＝80．当x＝50时，利润率＝×100%≈66.7%＜100%，符合题意；当x＝80时，利润率＝×100%≈166.7＞100%，不合题意，舍去．答：该礼盒的销售单价应定为50元．24．【解答】解：（1）过点E作EK⊥AD于点K，如图1，设OE＝x，∵AE平分∠OAD，∴KE＝OE＝x，则DE＝EK＝x，∵四边形ABCD为正方形，∴AOD为等腰直角三角形，则BD＝AD＝2＝2OD＝2（OE+ED）＝2（x+x），解得x＝（﹣1），则DE＝x＝2﹣2；（2）过点E作AB的平行线交AD于点G，交BC于点H，过点E作ES⊥AB于点S，∵BD是正方形ABCD的对角线，故∠EBH＝45°，∴△BEH为等腰直角三角形，同理△BES为等腰直角三角形，故四边形SEHB为正方形，则SE＝BH＝AG＝EH，即AG＝EH，∵∠AEG+∠FEH＝90°，∠FEH+∠EFH＝90°，∴∠AEG＝∠EFH，而∠ESA＝∠EHF＝90°，∴△ESA≌△EHF（AAS），∴AE＝EF；（3）在图2的基础上，过点E作ER⊥CD交于点R，根据正方形的对称性，AE＝EC，而AE＝EF，∴EF＝EC，则FC＝2CH＝2ER，则FC＝2HC＝2GD＝2×DE＝DE．25．【解答】解：（1）对于y＝﹣2（x+1）2+3，令x＝0，则y＝1，故点A（0，1），顶点P的坐标为（﹣1，3），则“风车线”的表达式为y＝k（x+1）+3，将点A的坐标代入上式并解得：k＝﹣2，故“风车线”的解析式为y＝﹣2（x+1）+3＝﹣2x+1；（2）y＝kx+3k﹣2＝k（x+3）﹣2，故点P的坐标为（﹣3，﹣2），故平移后的抛物线表达式为y＝﹣（x+3）2﹣2；（3）∵抛物线的表达式为y＝﹣2（x﹣2）2+1，则点P（2，1），则“风车线”的表达式为y＝k（x﹣2）+1，联立，解得，故点A（2，5），故AP＝5﹣1＝4，则△ABC的面积＝S+S△APC＝×4×（x C﹣x B）＝12，△APB解得：x C﹣x B＝6，设点B的横坐标为t，则点C的横坐标为t+6，点B在直线m上，则点B（t，t+3），同理点C（t+6，﹣2t﹣3），将点B、C的坐标分别代入y＝k（x﹣2）+1，得，解得或，故“风车线”的表达式为y＝k（x﹣2）+1＝﹣（x﹣2）+1＝﹣x+3或y＝1．26．【解答】解：（1）∵点D坐标是（，6），B点的坐标是（4，6），四边形OABC为矩形，∴BC＝AO＝4，OC＝AB＝6，CD＝，BD＝BC﹣CD＝，∵将矩形沿直线DE折叠，∴DF＝CD＝，∴BF＝＝＝2，∴AF＝6﹣2＝4，∴点F（4，4）．（2）如图2中，连接PF交DE于J．当四边形EFDP是矩形时，△PDE≌△FED≌△CED，∵C（0，6），F（4，4），∴直线CF的解析式为y＝﹣x+6，∵DE垂直平分线段CF，∴直线DE的解析式为y＝2x+1，∴E（0，1），D（，6），∵DJ＝JE，∴J（，），∵PJ＝JF，∴P（﹣，3）．（3）如图3中，连接FN，以FN为对角线构造正方形NMFM′，连接MM′交FN于K．设N（m，2m+1），则K（，），M（，），M′（，），当点M落在x轴上时，＝0，解得m＝﹣，当点M′落在X轴上时，＝0，解得m＝﹣9，∴满足条件的点N的坐标为（﹣，）或（﹣9，﹣17）．。
