k graphs

Find the value of k , if the graph of the function y = 3 x 2 - 6 x + k has a vertex at (2, 3). => - 24 or 9 or 15 or 3..

Let OAB is an isosceles triangle with O(0, 0) and A is on the positive x -axis such that OA = k which is the base. If B lies on the graph y = 6 - x 2 , then find the area of triangle in terms of k . => k 8 ( 2 4 - k 2 ) or k 8 ( 2 4 - ..

Find the value of k if the line y = k is the horizontal asymptote of the graph of the function f ( x ) = 9 x 2 8 + 9 x 2 . => -9 or 1 or - 1 or 9..

Find the equation of a function whose graph is a parabola with an axis of symmetry of x = - 9 . => y = a ( x + 9) 2 + k or y = a ( x - 9) 2 - k or y = a ( x - 9) 2 + k or y = a ( x + 9) 2 - k..

A graph shown below is plotted with pressure in atmosphere on y -axis and volume in m 3 on x -axis. Which of the following holds well? => P V = constant or PV = constant or PV 2 = k or P 2 V 3 = constant..

The boiling point of a liquid may be defined as the temperature at which the vapor pressure of the liquid becomes equal to the atmospheric pressure. fig 3.9 The vapor pressure curves for the pure solvent and solution consisting of a nonvolatile solute is represented diagrammatically. AB is the vapo..

Identify the incorrect statement from the following. => The graph of a direct variation model is a line that always passes through the origin. or The circumference of a circle is directly proportional to the diameter of the circle. or In the direct variation model 5 x = y , 1 5 is the con..

. Hence, a diode acts like a one-way valve in a circuit, and is then called a rectifie..

The condition in which a particular material exists is described by physical quantities such as pressure, volume, temperature and amount of substance. For example, a tank of oxygen in a welding outfit has a pressure gauge and a label stating its volume. We could add a thermometer and place the tank..

Series Reactions (First Order) - A complex reaction involving two series reactions can be of the type, A reacts to give B, which is then transformed to C. Both the elementary reactions (1) and (2) exhibit first - order kinetics, that is, For this reaction, [A] = [A] o exp (-k 1 t) (36) It..
