案1.B解析(方法一)2+3i3-2i=(2+3i)(3+2i)(3-2i)(3+2i)=13i13=i.(方法二)2+3i3-2i=(2+3i)i(3-2i)i=(2+3i)i2+3i=i.2.A解析 M=x|0 x0,则 a1+a2=(a2-d)+(a5-3d)=(a2+a5)-4d.由于 d的正负不确定,因而 a1+a2的符号不确定,故选项 A 错误.假设 a1+a30,则 a1+a2=(a1+a3)-d.由于 d的正负不确定,因而 a1+a2的符号不确定,故选项 B 错误.假设 0a10.所以 a30,a40.所以?32-a2a4=(a1+2d)2-(a1+d)(a1+3d)=d20.所以 a3?2?4.故选项 C正确.由于(a2-a1)(a4-a2)=d(2d)=2d2,而 d有可能等于 0,故选项 D 错误.8.D解析 连接 PO,由题意知,PO底面 ABCD,PO=R,S正方形ABCD=2R2.因为 V正四棱锥P-ABCD=163,所以13 2R2 R=163,解得 R=2.所以球 O 的外表积是 16.9.D解析 如图,作出题中不等式组所表示的平面区域.由 z=kx-y得 y=kx-z,要使目标函数 z=kx-y 仅在点 A(0,2)处取得最小值,则阴影部分区域在直线y=kx+2的下方,故目标函数线的斜率 k 满足-3k 1.10.D解析 由该几何体的三视图可得其直观图为如下图的三棱锥,且从点 A 出发的三条棱两两垂直,AB=1,PC=6,PB=a,BC=b.文档编码:CD9K10A4A5C5 HT10A5Q7R8E1 ZZ2J4H3C7X10文档编码:CD9K10A4A5C5 HT10A5Q7R8E1 ZZ2J4H3C7X10文档编码:CD9K10A4A5C5 HT10A5Q7R8E1
