Frame the formula from the following table. Make Z the subject of the formula.
`{:(X,1,2,1,2,3),(Y,1,2,2,1,4),(Z,2sqrt(2),sqrt(2),sqrt(5),sqrt(5),5):}`
Correct Answer - B
(2) Tangent to `y^(2)=4x` in terms of m is
`y=mx+(1)/(m)` (1)
Normal to `x^(2)=4by` in terms of m is
`y=mx+2b+(b)/(m^(2))` (2)
Equation (1) and (2) represent same...
Correct Answer - B
(2) Let `y_(1)=3+sqrt(1-x_(1)^(2))andy_(2)=sqrt(4x_(2))`
`orx_(1)^(2)+(y_(1)-3)^(2)=1andy_(2)^(2)=4x_(2)`
Thus, `(x_(1),y_(1))` lies on the circle `x^(2)+(y-3)^(2)=1`.
Also, `(x_(2),y_(2))` lies on the upper half of the parabola `y^(2)=4x`.
Thus, the given expression is...
