câu 4:

hệ pt: \(\left\{{}\begin{matrix}2x-y=1\\x+y=2\end{matrix}\right.\)\(< =>\left\{{}\begin{matrix}2x-y=1\\2x+2y=4\end{matrix}\right.< =>\left\{{}\begin{matrix}-3y=-3\\2x-y=1\end{matrix}\right.\)

\(< =>\left\{{}\begin{matrix}y=1\\x=1\end{matrix}\right.\) vậy hệ phương trình có nghiệm (x,y)=(1;1)

b, 

gọi thời gian làm riêng của An là x(ngày)

thời gian làm riêng của Bình là y(ngày)

=>1 ngày An làm \(\dfrac{1}{x}\)(công việc)

1 ngày Bình làm \(\dfrac{1}{y}\)(công việc)

2 người làm chung mất 2 ngày

=>pt: \(\dfrac{1}{x}+\dfrac{1}{y}=\dfrac{1}{2}\left(1\right)\)

4 ngày An làm : \(\dfrac{4}{x}\)(công việc)

vì sau 4 ngày An làm việc rồi nghỉ thì Bình làm tiếp trong 1 ngày hoàn thành công việc

=>pt: \(\dfrac{4}{x}+\dfrac{1}{y}=1\left(2\right)\)

từ(1)(2)=>\(\left\{{}\begin{matrix}\dfrac{1}{x}+\dfrac{1}{y}=\dfrac{1}{2}\\\dfrac{4}{x}+\dfrac{1}{y}=1\end{matrix}\right.\)(\(x,y\ne0\)) Đặt \(\dfrac{1}{x}=a,\dfrac{1}{y}=b\)

=>\(\left\{{}\begin{matrix}a+b=0,5\\4a+b=1\end{matrix}\right.< =>\left\{{}\begin{matrix}a=\dfrac{1}{6}\\b=\dfrac{1}{3}\end{matrix}\right.\)=>\(\left\{{}\begin{matrix}\dfrac{1}{x}=\dfrac{1}{6}\\\dfrac{1}{y}=\dfrac{1}{3}\end{matrix}\right.< =>\left\{{}\begin{matrix}x=6\left(TM\right)\\y=3\left(TM\right)\end{matrix}\right.\)

vậy AN làm công việc riêng trong 6 ngày

Câu 1

1) \(A=\sqrt{20}-\sqrt{45}+\sqrt{6+2\sqrt{5}}\)

\(=2\sqrt{5}-3\sqrt{5}+\sqrt{\left(\sqrt{5}\right)^2+2\sqrt{5}+1}\)

\(=-\sqrt{5}+\sqrt{\left(\sqrt{5}+1\right)^2}\)

\(=-\sqrt{5}+\sqrt{5}+1\)

\(=1\)

2) ĐKXĐ: \(x>0;x\ne1\)

\(B=\left(\dfrac{1}{x-\sqrt{x}}+\dfrac{1}{\sqrt{x}-1}\right):\dfrac{\sqrt{x}+1}{\left(\sqrt{x}-1\right)^2}\)

\(=\left(\dfrac{1}{\sqrt{x}\left(\sqrt{x}-1\right)}+\dfrac{1}{\sqrt{x}-1}\right).\dfrac{\left(\sqrt{x}-1\right)^2}{\sqrt{x}+1}\)

\(=\dfrac{1+\sqrt{x}}{\sqrt{x}\left(\sqrt{x}-1\right)}.\dfrac{\left(\sqrt{x}-1\right)^2}{\sqrt{x}+1}\)

\(=\dfrac{\sqrt{x}-1}{\sqrt{x}}\)

\(\Rightarrow B=\dfrac{\sqrt{x}-1}{\sqrt{x}}=\dfrac{1}{2}\)

\(\Leftrightarrow2\left(\sqrt{x}-1\right)=\sqrt{x}\)

\(\Leftrightarrow2\sqrt{x}-2=\sqrt{x}\)

\(\Leftrightarrow2\sqrt{x}-\sqrt{x}=2\)

\(\Leftrightarrow\sqrt{x}=2\)

\(\Rightarrow x=4\left(tmđk\right)\)

2) \(\left\{{}\begin{matrix}2\left(x+2\right)=3\left(y-1\right)\\3x+y=6\end{matrix}\right.\Leftrightarrow\left\{{}\begin{matrix}2x+4=3y-3\\3x+y=6\end{matrix}\right.\)

Áp dụng hệ thức: \(\sin^2\alpha+\cos^2\alpha=1\Rightarrow\cos^2\alpha=1-\sin^2\alpha\)

\(\Rightarrow\cos^2\alpha=1-0,6^2=0,64\)

\(\Rightarrow\cos\alpha=\pm0,8\)

Mà \(\alpha\) là góc nhọn nên \(\cos\alpha>0\) do đó \(\cos\alpha=0,8\)

Ta có: \(\tan\alpha=\dfrac{\sin\alpha}{\cos\alpha}=\dfrac{0,6}{0,8}=0,75\)
