17.某网球中心欲建连成片的网球场数块,用128万元购买土地10000平方米,该网球中心每块球场的建设面积为1000平方米,球场的总建筑面积的每平方米的平均建设费用与球场数有关,当该网球中心建球场 块时,每平方米的平均建设费用(单位:元)可近似地用 来刻画。
(1)求球场数 的取值范围;
且 ,数列{ }是以1为首项,1为公差的等差数列
又 ∠BAD=∠ADC=90°, ,
∴ ,∠CAB=45°,∴ , BC⊥AC.………………5分
又 , 平面BB1C1C, AC⊥平BB1C1C.…7分
(Ⅱ)存在点P,P为A1B1的中点.………………………………………8分
证明:由P为A1B1的中点,有PB1‖AB,且PB1= AB.…………………9分
