Answer:

0.1. Let x be rational and y be irrational. Is xy necessarily irrational ? Justify your

answer by an example.

0.2. += -1(x, y# 0), Find the value of x3 – y3.

0.3. By Remainder Theorem find the remainder, when p(x) is divided by g(x),

where p(x)=x3 - 2x2 - 4x -- 1

g(x) =

x+1

0.4. What is relation between height, radius and slant height of a cone?

0.5. Check whether the graph of the equation

y = 3x + 5 passes through the origin or not.
