求這道題的詳細解答過程(計算也要詳細過程)。謝謝!
3樓:西域牛仔王
圓方程配方,
得 (x - 1)²+(y - 2)²=5,圓心 (1,2),半徑 r=√5,
圓心到已知直線的距離為 d=|3 - 2 - 6| / √(9+1)=√10 / 2,
所以弦長 |ab|=2√(r² - d²)=√10 。
請問下面的五道四則運算題怎麼做, 要帶過程和答案,謝謝啦

=28/25+[(9/6+16/6)÷15/4-0.4]+80/9=28/25+[(9/6+16/6)÷15/4-0.4]+80/9=28/25+[10/9-10/25]+80/9=10+18/25
=10又18/25
b. [(15/28-11/36)×
答21/29+6又2/7÷16/21]÷16又1/2=[45/(4×29)-77/(12×29)+(44×21)/(7×16)]÷33/2
=[1/6+33/4]÷33/2

=101/198
c. 1-[(2又1/2-1又1/3)÷1又1/6]÷4又1/2+2又1/3
=1-[7/6÷7/6]÷9/2+7/3
=1-2/9+21/9
=1+19/9
=3又1/9
d.[1÷(3.1-3.09)]÷(1/3+0.8+8/15)=100÷5/3
=60e. 1998×1999-1995×2002=1998×1999-(1998-3)×(1999+3)=1998×1999-(1998×1999-3×1999+1998×3-9)
=1998×1999-(1998×1999-12)=12
