Vedclass · Answer

(B) Given equations are $y^2 = 4x$ and $x^2 + y^2 = 5$.Substituting $y^2 = 4x$ into the circle equation: $x^2 + 4x = 5$.$x^2 + 4x - 5 = 0 \Rightarrow (x + 5)(x - 1) = 0$.Since the intersection is in the first quadrant,$x = 1$.For $x = 1$,$y^2 = 4(1) = 4$,so $y = 2$ (as $y > 0$ in the first quadrant).The point of intersection is $P(1, 2)$.The equation of the tangent to $y^2 = 4x$ at $(x_1, y_1)$ is $yy_1 = 2(x + x_1)$.Substituting $(1, 2)$: $2y = 2(x + 1) \Rightarrow y = x + 1$.Checking the options,for $x = \frac{3}{4}$,$y = \frac{3}{4} + 1 = \frac{7}{4}$.Thus,the tangent passes through $\left( \frac{3}{4}, \frac{7}{4} \right)$.

The tangent to the parabola $y^2 = 4x$ at the point where it intersects the circle $x^2 + y^2 = 5$ in the first quadrant,passes through the point
