谁能告诉我这几个英语单词和句子怎么读啊?用汉语标出来.单词：active,quiet,very.句子:who s your art teacher?wat s he like?He s short and thin.who s your principal?no she s oid.she s very kind.句子帮我翻译一下，那个2楼的，我不是不想学音标，是因为我实在掌握不好，我试过，你有没有什么好的办法能告诉我，

反三角函数求定义域,
若二次函数y=x2+x+m（m-2）的图象经过原点，则m的值必为（　　）A. 0或2B. 0C. 2D. 无法确定
∵y=x2+x+m（m-2）的图象经过原点，把点（0，0）代入得：m（m-2）=0，解得m=0或m=2．故选A．
如图,二次函数图像过A、C、B三点,点A的坐标为（-1,0）,点B的坐标为（4,0）,点C在y轴正半轴上,且AB=OC1.求C点坐标；2.求二次函数的解析式,并求出函数的最大值.
0,得：a">-1,4即为两根,可设y=a(x+1)(x-4)=a(x^2-3x-4)y(0)=-4a>0,得：a
matlab怎么调用function函数给变量赋值计算如下函数function a =fun2(m,Cd,p,Ax,Vx,Ay,Vy,Az,Vz,t)x = 1/(4*m)*Cd*p*Ax*(Vx*t)^2;y = 2*m/(Cd*p*Ay)log(1/(2*m)*Cd*p*Ay*Vy*t+1)； %在MATLAB中lnx用log(x)表示z =1/(4*m)*Cd*p*Az*(Vz*t)^2;a = [x y z];end最好能输出结果和图像log前加一个*
设全集U=R,集合A={X/Y=log2底（-X方+2x+3)},B={Y/Y=2的X方,（-无穷,2）},C={X/a小于X小于2a-1} (1) 求(1) 求A B(2) 若C包含于（A交B),求实数a的取值范围
(1).A={X/Y=log2底（-X方+2x+3)}-X方+2x+3＞0-1＜x＜3A=（-1,3）B={Y/Y=2的X方,（-无穷,2）}可画图,由图得,0＜y＜4B=（0,4）（2）A∩B=（0,3）1,C是空集,则a＜12,C不是空集,则1＜a＜2综上所述,a的取值范围是（-无穷,2）
图象恒在x轴上方所以(2a)^2-4*34a^2a^2所以-√3f(x)=x＾2+2ax+3f(a)-f(a+1)=-9f(a)=a^2+2a^2+3=3a^2+3f(a+1)=(a+1)^2+2a(a+1)+3=a^2+2a+1+2a^2+2a+3=3a^2+4a+4所以(3a^2+3)-(3a^2+4a+4)=-93a^2+3-3a^2-4a-4=-9-4a-1=-94a=8a=2

自动挡驾驶技巧(新手一定要读一读)
Automatic driving skills (novice must read).Txt 'cable' as many people earned the youth live sometimes touching is not worth mentioning things. Are broken is not the most cruel and most cruel is stepping on these fragments but pretended not to find the stubborn pain if I meet again how perfect people are the future, there is a disadvantage, he is not you, _____ next life to be male, marry a girl like me. Automatic car driving skills (novice must read)
Happy holidays have fun, travel to their car will know, if it is open automatic car riders, and then look at the following post experience. (this copy for a long time, he did not see the update, some content may be older, but this post is a good post, to open automatic speaking to buy automatic car riders often friends.)
1. gear introduction
The so-called automatic, as the name suggests, is no driver to manually shift, the vehicle will be based on the speed and traffic conditions automatically select the appropriate gear travel. But why are there still so many gears in the automatic transmission? Now let's make a brief introduction to the various gears and functions of the automatic transmission.
Take the Honda accord as an example. The gearbox of the new accord has P, R, N, D and 3,2,1 gears,
P stands for parking, parking (off engine and idle parking for extended periods)! ~
R stands for reverse gear, and I'm sure I don't need to explain! ~
N stands for neutral and manual transmission, meaning for short parking! ~
D indicates the forward gear. Under this gear, the gearbox will switch automatically in the 1~5 gear according to the speed and the throttle
3, also the forward gear, in this gear, the gearbox in the 1~3 stalls automatically switch, will not rise to 4, 5, two files. It can be used as a restricted gear when the traffic is not smooth, and the jumping between the 3 gears and the 4 stalls can be avoided! (specifically how it is avoided will be introduced below)
2 stands for the 2 gear, w
