问题 填空题

给出两个命题:p:ax2+ax+1>0对x∈R恒成立.q:函数y=(a2-2a-2)x是增函数.若“p∧(¬q)”是真命题,则实数a的取值范围是______.

答案

若命题:p:ax2+ax+1>0对x∈R恒成立为真命题.

则a=0或

a>0
a2-4a<0
,综上可得0≤a<4

若命题q:函数y=(a2-2a-2)x是增函数.

则a2-2a-2>1,解得:a<-1,或a>3

又∵“p∧(¬q)”是真命题,

故p为真命题,q为假命题

0≤a<4
-10≤a≤3

解得0≤a≤3

故答案为:0≤a≤3

Although I love my life ,it hasn't been a lot of fun as I've been ill for 28 years

Music has always been a great love of mine and ,in my 20s,when my_21_was move manageable ,I  22  ten years as a professional singer in restaurant .playing and singing falk songs.  23 that was years ago and times have changed . __24__ I live with my mother on a country farm .

My family are all musicians ,so I was _29 when I went into our local music store .I explained that I waned to sing again but using  recurded knraoke music I knew that discs were very expensive and I really didn't have a lot of  _30 to get started ,And    31    you find only three to four songs out of ten on a disc that you can __32__use.

When I told the owner of the shop about my    33  ,he gave me a long use the gave me a long ,thoughtful  __34__.

“This means a lot to you , doesn't it ?"be said . “Come with me.”

He led me    35  the crowded shop and to a bench with a large professional karaoke box on it.  He placed his large hand   36  on his treasure and said . “I have 800 karaoke songs in here. You can take your   37    and I´ll record them for you .That should get you started.”

His   40  still warms my heart and makes me do just that bit extra , which I have the chance.
