12 sai, C mới là đáp án đúng 

13 sai, A đúng, \(sin-sin=2cos...sin...\)

18.

\(\Leftrightarrow\left\{{}\begin{matrix}a=m>0\\\Delta'=m^2-m\left(-m+3\right)< 0\end{matrix}\right.\)

\(\Leftrightarrow\left\{{}\begin{matrix}m>0\\2m^2-3m< 0\end{matrix}\right.\) \(\Leftrightarrow\left\{{}\begin{matrix}m>0\\0< m< \dfrac{3}{2}\end{matrix}\right.\) \(\Rightarrow m=1\)

Đáp án B

22.

Để pt có 2 nghiệm pb \(\Leftrightarrow\left\{{}\begin{matrix}m-2\ne0\\\Delta'=\left(2m-3\right)^2-\left(m-2\right)\left(5m-6\right)>0\end{matrix}\right.\)

Theo hệ thức Viet: \(\left\{{}\begin{matrix}x_1+x_2=\dfrac{-2\left(2m-3\right)}{m-2}\\x_1x_2=\dfrac{5m-6}{m-2}\end{matrix}\right.\)

\(\dfrac{-2\left(2m-3\right)}{m-2}+\dfrac{5m-6}{m-2}\le0\)

Đề bài câu này dính lỗi, ko có điểm M nào cả, chắc là đường thẳng đi qua A

Đường tròn (C) tâm I(1;-2) bán kính R=4

\(\overrightarrow{IA}=\left(1;3\right)\)

Gọi d là đường thẳng qua A và cắt (C) tại 2 điểm B và C. Gọi H là trung điểm BC

\(\Rightarrow IH\perp BC\Rightarrow IH=d\left(I;d\right)\)

Theo định lý đường xiên - đường vuông góc ta luôn có: \(IH\le IA\)

Áp dụng Pitago cho tam giác vuông IBH: 

\(BH=\sqrt{IB^2-IH^2}\Leftrightarrow\dfrac{BC}{2}=\sqrt{16-IH^2}\)

\(\Rightarrow BC_{min}\) khi \(IH_{max}\Leftrightarrow IH=IA\)

\(\Leftrightarrow IA\perp d\Rightarrow d\) nhận \(\overrightarrow{IA}\) là 1 vtpt

Phương trình d: 

\(1\left(x-2\right)+3\left(y-1\right)=0\Leftrightarrow x+3y-5=0\)
