數學考題練習:美是一種感覺,當人的肚臍是人的身高的黃金分割點

更新時間:2024-01-12 16:28:29作者:貝語網校

美是一種感覺,當人的肚臍是人的身高的黃金分割點時,人的下半身長與身高之比約為0.618,人的身段成為黃金比例,給人一種美感.某女士身高165cm,下半身長與身高的比值是0.60,為盡可能達到勻稱的效果,她應穿高跟鞋的高度大約為

A.4cm

B.5cm

C.6cm

D.8cm

試題答案

D

試題解析

先求得下半身的實際高度,再根據黃金分割的定義求解.

解答:∵某女士身高165cm,下半身長與身高的比值是0.60,

∴此女士下半身長是165×0.60=99cm,

設需要穿的高跟鞋是xcm,根據黃金分割的定義得:

=0.618,

解得:x≈8.

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.
