已知集合A={x|x2－2014x＋2013<0},={x|log2x

}(m∈n∗),若a⊆b,则m的最小值是__.

As shown in Fig.3, AB=6, BC=8, CA=10. Point P is inside of the triangle ABC. DE, FG, and IH all pass point P and are parallel to AB, BC, and CA, respectively. The lengths of DE, FG and IH are all equal to d,then d= ___.(英汉小词典:parallel平行)

若函数f(x)=(a+2)x2-ax+(2a-1)的两个零点分别在区间(-2,-1)和区间(0,1)内,则a的取值范围是___.

若关于x的不等式2kx2>(x-2)2恰有4个整数解,则实数k的取值范围是___.

若函数f(x)={-x+1,x-1,x

设f(x)是R上的减函数,且f(0)=3,f(3)=-1.已知P={x||f(x+t)-1|
