(1)Q(10-2T,0)P(T 3)
∵的BP“AQ
∴PQAB一个平行四边形时,BP = AQ
BP = 6吨,AQ = 10-2T
BP = AQ介绍了6吨= 10-2T
解决方案T = 2
(2)∵BP“AQ
∴PQAB等腰梯形QP = AB
AB =√(4 ^ 2 3 ^ 2)= 5
PQ =√[(10-3吨)^ 2 3 ^ 2] =√(9吨^ 2 - 60吨+ 109)
AP = PQ推出9(T).但该模型不能反映污染 - 诱导^ 2-60T +109 = 25
(T).但该模型不能反映污染 - 诱导^ 2-60T +84 = 0
3吨^ 2-20T +28 = 0
(3T?14)(T-2)= 0
>解决方案T1 = 14/3,T2 = 2
∵T = 2 PQAB一个平行四边形((1)已被证实)
吨= 14/3
