Let \( P(x, y) \)
\[ \frac{(x - 2)^2 + (y - 1)^2}{(x - 1)^2 + (y - 3)^2} = \frac{25}{16} \]
Expanding and simplifying:
\[ 9x^2 + 9y^2 + 14x - 118y + 170 = 0 \]
From the equation:
\[ a^2 + 2b + 3c + 4d + e = 81 + 18 + 0 + 56 - 118 \]
Calculating:
\[ = 155 - 118 \]
\[ = 37 \]
If the four distinct points $ (4, 6) $, $ (-1, 5) $, $ (0, 0) $ and $ (k, 3k) $ lie on a circle of radius $ r $, then $ 10k + r^2 $ is equal to
The shortest distance between the curves $ y^2 = 8x $ and $ x^2 + y^2 + 12y + 35 = 0 $ is:
Let the equation $ x(x+2) * (12-k) = 2 $ have equal roots. The distance of the point $ \left(k, \frac{k}{2}\right) $ from the line $ 3x + 4y + 5 = 0 $ is
