The numerically greatest term in the expansion of $$(2 + 3x)^5$$ when $$x = \frac{5}{4}$$ is
The value of x for which the matrix $$\begin{bmatrix}x-2 & 2x-3 & 3x-4 \\x-4 & 2x-9 & 3x-16 \\x-8 & 2x-27 & 3x-64 \end{bmatrix}$$ does not possess inverse, is
In the adjoining figure, ABCD is a cyclic quadrilateral in which AC and BD are its diagonals. If $$\angle DBC = 55^\circ$$ and $$\angle BAC = 45^\circ$$, then $$\angle BCD =$$
A and B are the end points of the longest line drawn in the circle with centre x. If C is a point on the circle such that AC = Ax = 3. Then the perimeter of $$\triangle ABC$$ is
A, B and C are three points on the circumference of a circle with centre O. If in $$\triangle ABC \angle B = 60^\circ$$ and $$\angle C = 70^\circ$$ then $$\angle BOC = $$
If A(3, 10), B (-3, 4) and C (5, 8) are the vertices of a $$\triangle ABC$$ and AD and CF are its medians. then the ratio of the length of AD to the length of CF is
If (-2, -1), (1, 0) and (4, 3) are three consecutive vertices of a parallelogram, then the sum of the lengths of the diagonals of that parallelogram is
