A point on the parabola

{y^2} = 18x

at which the ordinate increases at twice the rate of the abscissa, is

View answer and explanation

Correct option: D

\left( {\frac{9}{8},\frac{9}{{\;2}}} \right)\;

Option D

\left( {\frac{9}{8},\frac{9}{{\;2}}} \right)\;

is correct because it satisfies the given condition where the ordinate increases at twice the rate of the abscissa on the parabola.

cubic meters per minute, then the rate (in meters per minute) at which the radius of the balloon decreases 49 minutes after the leakage began is: A solid box is formed by placing a cylinder, having equal height and radius on top of a cube such that, the circular base of cylinder is the inscribed circle for square top of the cube. If the radius of cylinder is changing at the rate
