A) \[\frac{1}{2}\]
B) \[\frac{3}{2}\]
C) \[\frac{1}{8}\]
D) \[\frac{2}{3}\]
Correct Answer: A
Solution :
Now tangent with slope ?m? to \[{{y}^{2}}=4x\]is\[y=mx+\frac{1}{m}\] ?(1) Also tangent with slope ?m? to\[{{x}^{2}}=-32y\]is \[y=mx+\frac{1}{m}\] ?(2) If (1) and (2) are equations of the same line then their coefficients should match. \[\Rightarrow \]\[8{{m}^{2}}=\frac{1}{m}\]\[\Rightarrow \]\[m=\frac{1}{2}\]You need to login to perform this action.
