If the point (1, 4) lies inside the circle x ^ 2 + y ^ 2 - 6x + 10y...
If the point lies inside the circle and the circle does not touch or intersect the coordinate axes, then the set of all possible values of is the interval
Options
- A
- B
- C
- D
Correct answer
B.
Step-by-step solution
{x}^{2} + {y}^{2} - 6x - 10y + p = 0∴ and radius is .
the circle.
So,1 + 16 - 6 - 40 + p < 0⇒ p < 29 . . . \left(1\right)\sqrt{34 - p} < 5x - and \sqrt{34 - p} < 3y -⇒ 9 < p and 25 < p⇒ p > 25 . . . \left(2\right)
From equations \left(2\right),
So,
