了解。授人以鱼不如授人以渔嘛！Rio, + U! + U! !

DS题：一条直线T在x轴上截距是-1/4，y轴上截距是1，问另外一条直线U在y轴上的截距是多少。（1）U上的点（a，b）满足T上的点（b，a）（2）不记得了，好像能推出来。最后我选B，不知道对错。

这个答案到底是B还是D啊？

（1）不是可以推出U和T关y=x直线对称么。。。。那截距不是就知道了？

感谢RIO，真是辛苦你了！

请指点一下，下面这道题，谢谢！

542题可能是这道：

A certain company expects quarterly earnings of $0.80 per share of stock, half of which will be distributed as dividends to shareholders while the rest will be used for research and development.  If earnings are greater than expected, shareholders will receive an additional $0.04 per share for each additional $0.10 of per share earnings.  If quarterly earnings are $1.10 per share, what will be the dividend paid to a person who owns 200 shares of the company’s stock?

 

 

A.        $92

B.        $96

C.      $104

D.     $120

E.      $240

这题读懂了应该不难，

1) $0.80 per share of stock, half of which will be distributed as dividends to shareholders ==> 0.4*200

2) an additional $0.04 per share for each additional $0.10 of per share earnings ==> 0.04*200

3) quarterly earnings are $1.10 per share ==> 1.1 - 0.8 = 0.3 ==> 3 个 0.1

2) + 3) ==> 3*0.04*200

所以，0.4*200 + 3*0.04*200 = 104

你的ID让我看了好亲切啊。

建议还是考试的时候看原题

别人回忆的题目你也相信准确性？

B.        $96

C.      $104

D.     $120

E.      $240

 总盈利1.1，其中0.8分配0.4刀

剩下的0.3按照每0.1分配0.04，那么就一共分了0.12

也就是说每股分红0.52

这个人一共有200股，你说分多少？

580.DS题：一条直线T在x轴上截距是-1/4，y轴上截距是1，问另外一条直线U在y轴上的截距是多少。（1）U上的点（a，b）满足T上的点（b，a）（2）不记得了，好像能推出来。最后我选B，不知道对错。
        

还是直线题。

这道题，1）是不是也能推出来啊：（0，－1/4)=(-1/4,0)
