QUESTION: 1

### The length of the diameter of the circle which touches the x-axis at the point (1, 0) and passes through the point (2, 3) is

Solution:

Let the equation of the circle is

(x-1)2 + (y-k)2  = k2

It passes through (2, 3)

⇒ (2-1)2 + (3-k)2 = k2

⇒ 1+9+k2-6k = k2

⇒ 10-6k=0

⇒ k=-10/-6

⇒ k = 5/3

⇒ diameter = 10/3 QUESTION: 2

### The value of ii is :

Solution:

Let A=ii

⇒ log A = i log i

∵ ei θ = cos θ + i sin θ

∴ eiπ/2 = i

∴ i . π/2 = log i

∴ log A = i · i π/ 2 = - π / 2

⇒ A = e-π/2

QUESTION: 3

### If two vertices of a triangle are (5, -1), (-2, 3) and the orthocentre of the triangle lies at the origin, then the third vertex is

Solution:

Let the third vertex C be (x1 , y1) since O(0, 0) is the orthocenter

mCO × mAB = – 1 ⇒ y 1 - 0 x 1 - 0 · 3 - - 1 - 2 - 5 = - 1

⇒ y 1 x 1 · 4 7 = 1

⇒ 7 x 1 = 4 y 1

Also mBO × mAC = – 1

⇒ 3 - 2 × y 1 + 1 x 1 - 5 = - 1

⇒ 3 y 1 + 3 = 2 x 1 - 1 0

⇒ 3 × 7 4 x 1 + 3 = 2 x 1 - 1 0

⇒ x1 = – 4

y1 = – 7

Hence, the third vertex is (– 4, – 7)

QUESTION: 4

If a < 0, the function f(x) = eax + e- ax is a monotonically decreasing function for values of x

given by :

Solution:

f(x) = eax + e- ax

But a < 0

∴ e ax - e - ax > 0

⇒ e ax > e - ax

⇒ ax > - ax ⇒ 2 ax > 0

∴ ax > 0, then x < 0 (∴ a < 0)

QUESTION: 5

How many three-digit numbers can be formed without using the digits 0, 2, 3, 4, 5 and 6 ?

Solution:

Three-digit numbers are to be formed by using the digits 1, 7, 8 and 9.

To form a number of three digits, we are to fill up three places : the hundred's, the ten's and the unit's. The hundreds place can be filled in 4 different ways because anyone of 1, 7, 8 and 9 can fill up this place.

Similarly, ten's and unit's places can also be filled in 4 different ways each.

Accordingly, by FPC, the no. of three-digit numbers = 4 × 4 × 4 = 6 4
