The shortest distance from the line \(3 x+4 y=25\) to the circle \(x^2+y^2-6 x+8 y=0\) is
- A \(\frac{9}{5}\)
- B \(\frac{7}{5}\)
- C \(\frac{8}{5}\)
- D \(\frac{13}{5}\)
Answer & Solution
Correct Answer
(B) \(\frac{7}{5}\)
Step-by-step Solution
Detailed explanation
We have a line \(3 x+4 y=25\) and a circle \(x^2+y^2-6 x+8 y=0\) for shortest distance. We draw a perpendicular from \(\mathrm{C}=\) \((3,-4)\) to the straight line. \(\Rightarrow \mathrm{d}=\frac{|9-16-25|}{\sqrt{9+16}}=\frac{32}{5}\) hence shortcut distance…
