數(shù)學考題練習:美是一種感覺,當人體的下半身長與身高的比值越接

更新時間:2024-01-12 16:25:27作者:貝語網校

美是一種感覺,當人體的下半身長與身高的比值越接近0.618時越給人一種美感.已知某女士身高160cm,下半身長與身高的比值是0.60,為盡可能達到好的效果,她應穿的高跟鞋的高度約為

A.6cm

B.10cm

C.4cm

D.8cm

試題答案

D

試題解析

先求得下半身的實際高度,再根據(jù)黃金分割的定義求解.

解答:根據(jù)已知條件得下半身長是160×0.6=96cm,

設需要穿的高跟鞋是ycm,則根據(jù)黃金分割的定義得:=0.618,

解得:y≈8cm.

故選D.

點評:本題主要考查了黃金分割的應用.關鍵是明確黃金分割所涉及的線段的比,難度適中.
