A) \[\pm 1\]
B) \[\pm \frac{1}{3}\]
C) \[\pm \sqrt{5}\]
D) None
Correct Answer: C
Solution :
[c] We have, z = 0 for the point where the line intersects the curve. Therefore, \[\frac{x-2}{3}=\frac{y+1}{2}=\frac{0-1}{-1}\] \[\Rightarrow \frac{x-2}{3}=1\] and \[\frac{y+1}{2}=1\] \[\Rightarrow x=5\] and y=1 Put these value in \[xy={{c}^{2}},\] we get \[5={{c}^{2}}\] \[\Rightarrow c=\pm \sqrt{5}\]You need to login to perform this action.
