Whales are found in open seas throughout the world and occasionally in coastal waters，aswell.Certainspecies migrate，while others remain yearround in the samehabitats.Theskin of whales is usually black，gray，tan andwhite.Theirskin texture is smooth，but like other mammals，whales have hair at some point in theirdevelopmet.Inadutls it's ustallyfoumd only gn the head area，and in some spdcies only in thefetus.Whalesstore energy in an underskin layer of fat，orblubber.theability to store“fuel”in the form of blubber helps wiales survive during long periods ofstarvation.Exceptfor having horizontal tails that move up and down，rather than side to side，whales have tie general shape of fish，though in certain species the head is greatlyenlarged.Overmillions of years，hind limbsremain.Whalesbreathe through lungs，with some large species remaiming under water for as long as two hours.（1）what dose thd text mianly tell us？（not more than 10 words）

選取自由變數的問題
我知道一般是取非主元列為自由變數，但是應該也可以不是的吧？我想知道究竟原則是什麼，比如有這樣一道題
1 -1 2 0 3
0 0 1 3 -2
0 0 0 0 6
問你自由變數不能取成
A x4.x5 B x2，x3 C x2，x4 D x1，x3
因為前三列線性相關，那麼按答案的意思是你選的自由變數要使得剩下的那些不相關才行？然後就根據自由變數個數=n-ra的原則隨便選就行了？

答案是錯的！
這個應該選（C）
非零行（1,2,3行）的首非零元所在列（1,3,5列）對應的變數（x1，x3，x5）是約束變數，
其餘的（x2，x4）才是自由未知量
不知我說明白沒

x的平方—5X+4=0 .X得多少？

x^2-5x+4=0即（x-1）（x-4）=0所以x=1或x=4

集合A={y|y=x²；+2x=1，x∈R}，B={y|y=x²；-2x，x∈R}，則A∩B=_________
RT
請寫出答案與解題思路，謝謝！

A={y|y=x²；+2x+1，x∈R}={y|y=（x+1）^2>=0}={y|y>=0}
B={y|y=x²；-2x，x∈R}={y|y=（x-1）^2-1>=-1}={y|y>=-1}
則A∩B={y|y>=0}

數學計算題：18n+[n（n-1）/2]*（-3）=54怎麼計算的，

18n+[n（n-1）/2]*（-3）=54
36n-3n（n-1）=108
36n-3n^2+3n=108
-3n^2+39n=108
3n^2-39n=-108
n^2-13n=-36
n^2-13n+169/4=-36+ 169/4
（n- 13/2）^2=25/4
n- 13/2 =±5/2
n=±5/2+ 13/2
n=9或n=4

已知函數fx=x+a/x，且f1=2 1，求a 2，用定義證明，函數fx=x+1/x在區間[1，
已知函數fx=x+a/x，且f1=2 1，求a 2，用定義證明，函數fx=x+1/x在區間[1，+無窮）上是增函數

已知一個三角形的三個頂點座標是A（8,5），B（4，-2），C（-6,3），求分別經過其中兩邊種點所作的的三條直線的方程

AB中點為D（6,1.5）
BC中點為E（-1,0.5）
AC中點為F（1,4）
DE為y=1/7x+9/14
EF為y=1.75x+3.5
DF為y=-0.5x+4.5

電能表上面寫著：3000r/kw.h若測得轉盤在6min內轉了30圈，則所接用電器的總功率為___.

3000r/KW·h是表示轉3000圈走1KW·h那麼30圈就是30/3000=1/100KW·h6分鐘=6/60小時=1/10h則所接用電器的總功率P=W/t=（1/100）/（1/10）=0.1KW=100W3000r/kw.h若測得轉盤在6min內轉了30圈，則所接用電器的總功率為_0.1K…

若|a-1|+（b+2）的二次方=0，求（a+b）的兩千零八次方+a的兩千零一次方的值

|a-1|+（b+2）的二次方=0
所以：a-1=0
b+2=0
所以是：a=1 b=-2
（a+b）的兩千零八次方+a的兩千零一次方
=1 + 1
= 2
