已知点P为曲线xy-5/2x-2y+3=0上任意一点,O为坐标原点,则|OP|的最小值为()(A)5(1/2)/2.(B)6(1/2)/2.(C)2(1/2).(D)2*3(1/2)/3.本题是武汉市2015届高中毕业生二月调考理科数学选择题的最后一题.试题在曲线、函数、不等式的交汇处设计,多视角考查考生的基础知识和基本能力.从不同切入点入手,选取不同途经求解的难度差异较大.若从导数或双曲线的视角入手,则解
Known point P is any point on the curve xy-5/2x-2y+3=0, O is the origin of the coordinate, then the minimum value of |OP| is ()(A)5(1/2)/2.(B )6(1/2)/2.(C)2(1/2).(D)2*3(1/2)/3. This topic is the 2015 Mathematics Selection for the 2015 Senior High School Graduates in Wuhan. The last question of the question. The questions are designed at the intersection of curves, functions, and inequalities. The basic knowledge and basic ability of candidates are examined from multiple perspectives. Starting from different entry points, the difficulty of selecting different paths to solve is greater. If the derivative or double Starting from the perspective of the curve, the solution
