分小英与她的父亲、母亲计划外出旅游，初步选择了延安、西安、汉中、安康四个城市.由于时间仓促，他们只能去其中一个城市，到底去哪一个城市三人意见不统一.在这种情况下，小英父亲建议，用小英学过的摸球游戏来决定.规则如下：在一个不透明的袋子中装一个红球延安、一个白球西安、一个黄球汉中和一个黑球安康，这四个球除颜色不同外，其余完全相同；小英父亲先将袋中球摇匀，让小英从袋中随机摸出一球，父亲记录下其颜色，并将这个球放回袋中摇匀，然后让小英母亲从袋中随机摸出一球，父亲记录下它的颜色；假设两人所摸出球的颜色相同，则去该球所表示的城市旅游，否则，前面的记录作废，按规则重新摸球，直到两人所摸出球的颜色相同为止.按照上面的规则，请你解答以下问题:1已知小 英的理想 旅游城市是西安，小英和母亲随机各摸球一次，均摸出白球的概率是多少？2已知小英母亲的理想旅游城市是汉中，小英和母亲随机各摸球一次，至少有一人摸出黄球的概率是多少？23.此题总分值8 分如图，O的半径为4，B是 O外一点，连接OB，且 OB=6.过点 B作 O的切线 BD，切点为D，延长 BO交 O于点 A，过点 A作切线 BD的垂线，垂足为C.(1)求证：AD平 分 BAC；(2)求

M的坐标；3 将抛物线C 平移到 C ,抛物线 C的顶点记为M，它的对称轴于x 轴的交点记为N.如果以点 M、N、M、N为顶点的四边形是面积为16 的平行四边形，那么应将抛物线C 怎样平移？为什么？25.此题总分值12 分问题探究1如图，在矩形ABCD 中，AB=3，BC=4.如果 BC边上存在点P，使 APD为等腰三角形，那么请画出满足条件的一个等腰 APD，并求出此时BP的长；2如图，在 ABC中，ABC=60 ，BC=12，AD是 BC边上的高，E、F分别为边AB、AC的中点.当 AD=6时，BC边上存在一点Q，使 EQF=90，求此时BQ的长；问题解决3有一山庄，它的平面图为如图的五边形ABCDE，山庄保卫人员想在线段CD上选一点M安监控装置，用来监视边AB.现只要使 AMB 大约为 60，就可以让监控装置的效果到达最正确.已知A=E=D=90，AB=270m，AE=400m,ED=285m，CD=340m.问在线段CD上是否存在点M，使 AMB=60？假设存在，请求出符合条件的DM的长；假设不存在，请说明理由.图图图文档编码:CF4N2R3R9B3 HY2B10C6D8Y6 ZE9U5S4M2C5文档编码:CF4N2R3R9B3 HY2B10C6D8Y6
