For the following questions answer them individually
If $$p, q, r$$ are three statements, then $$(p \rightarrow (q \rightarrow r))$$ is equivalent to
The contrapositive of the statement $$p \rightarrow q$$ is
Let $$A = \left\{x ∈ ℝ \mid x^2 < 9\right\}$$ and $$B = \left\{x ∈ ℝ \mid 4 < x^2 < 16\right\}$$ then $$A \cap B =$$
If a set A has 3 elements, then the number of reflexive relations that can be defined on A is
For $$x \neq 0$$ define $$f : ℝ \rightarrow ℝ$$ by $$2f(x) = 3f \left(\frac{1}{x}\right) = x^2$$. Then f(3) =
The y-intercept of the line $$\frac{3y - 7}{4} = \frac{4x + 1}{5}$$
If a line passes through the points (-7, 18) and (32, 5), then the sum of the intercepts made by the line on the coordinate axes is
$$\tan 85^\circ \tan 50^\circ - \tan 85^\circ - \tan 50^\circ =$$
If $$\sec A + \tan A = \frac{1}{5}$$, then the quadrant in which $$\angle A$$ lies is
