解题方法
【推荐2】潮汐现象是发生在沿海地区的一种自然现象,是指海水在天体(主要是月球和太阳)引潮力作用下所产生的周期性运动,我们把海面垂直方向涨落称为潮汐,地球上不同的地点潮汐规律不同.
下表给出了某沿海港口在一天(24小时)中海水深度的部分统计数据:
(1)请结合表中数据,在给出的平面直角坐标系中,选择合适的点,画出该港口在一天24小时中海水深度
与时间
的函数图像,并根据你所学知识,请从
,
,
(
,
,
),
(
,
,
)这四个函数解析式中,选取一个合适的函数模型描述该港口一天24小时内水深
与时间
的函数关系,求出其解析式;

(2)现有一货轮需进港卸货,并在白天进行物资补给后且于当天晚上 离港.已知该货轮进港时的吃水深度(水面到船底的距离)为10米,卸货后吃水深度减小0.8米,根据安全航行的要求,船底至少要留出2.8米的安全间隙(船底到海底的距离),如果你是船长,请你规划货轮的进港、离港时间,并计算出货轮在该港口停留的最短时长.(参考数据:
