在日常生活和生产技术中,我们常常会遇到一些最佳选址的问题.对于此类问题,同学们往往是望而生畏,不知从何入手.此时如果能够灵活运用解析几何知识,最佳选址还是容易确定的.下面举例分析,希望对同学们能够有所启迪.1利用直线确定最佳选址例1如图1所示,两个生物制药厂A、B座落于通江运河河岸的同侧,工厂A、B距离河岸分别为4km、2km,它们之间的距离为6km.现要在运河的工厂这侧
In daily life and production technology, we often encounter some of the best site for the problem .For such problems, students are often daunting, I do not know where to start .At this time if you have the flexibility to use analytic geometry, the best choice The site is still easy to determine the following example analysis, I hope the students can be enlightened.1 using straight line to determine the best site Example 1 As shown in Figure 1, two biopharmaceuticals A, B is located in the river bank Of the same side, the factory A, B from the riverbank were 4km, 2km, the distance between them is 6km. Now on the side of the canal factory
