Question

# The line among the following that touches the is

Hint:

### The equation of tangent to parabola is given as with slope = m.

Similarly find the equation of tangent to parabola with slope = and simplify.

## The correct answer is:

### Condition 1

The line with slope 'm' is a tangent to parabola

The equation of tangent to parabola is given as (slope = m)

Condition 2

If slope = , then equation of tangent

Thus, equation of lines touching parabola with slope is .

### In how many ways can six different rings be wear in four fingers?

It is important to note that we have used a basic fundamental principle of counting to find the total ways. Also, it is important to notice that each ring has 4 ways as it has not been given that each finger must have at least one ring. So, there can be 6 rings in a finger alone and remaining all the fingers empty.

### A tea party is arranged of 16 persons along two sides of a long table with 8 chairs on each side. 4 men wish to sit on one particular side and 2 on the other side. In how many ways can they be seated ?

Whenever we face such types of problems the key point is to make special arrangements for the people who are in need of it, then arrange the remaining. Now combination comes with permutation as there are possibilities of these 8 people sitting on one side to rearrange. Thus this concept into consideration, to get through the answer.
