\(P(A \cap \bar{B})=P(A)-P(A \cap B) \)
\(\frac{1}{2} =\frac{7}{10}-P(A \cap B) \)
\(P(A \cap B) =\frac{7}{10}-\frac{1}{2}=\frac{1}{5} \)

\(\frac { \pi }{ 4 } \)

\(\log _{\sqrt{x}} 0.25 =4 \)
\((\sqrt{x})^{4} =0.25 \)
\((\sqrt{x})^{4} =\frac{1}{4} \)
\(x^{2} =\frac{1}{4} \)
\(\Rightarrow x=\frac{1}{2}=0.5\)

\(x^{2}+a x+b=0\)
\(\text { Let } \tan \alpha \text { and } \tan \beta \text { be the roots. }\)
\(\tan \alpha+\tan \beta =-a \)
\(\tan \alpha \tan \beta =b \)
\(\frac{\sin (\alpha+\beta)}{\sin \alpha \sin \beta} =\frac{\sin \alpha \cos \beta+\cos \alpha \sin \beta}{\sin \alpha \sin \beta} \)
\(=\cot \beta+\cot \alpha \)
\(=\frac{1}{\tan \alpha}+\frac{1}{\tan \beta} \)
\(=\frac{\tan \alpha+\tan \beta}{\tan \alpha \tan \beta}=\frac{-a}{b} \)

10.

\(f(x) =\sin x+\cos x \)
\(f(-x) =\sin (-x)+\cos (-x) \)
\(=-\sin x+\cos x \)
\(-f(-x) =\sin x-\cos x \)
\(f(x) \neq-f(-x) \)
f(x) is neither odd function nor even function.
