14.	If a = (√3 + √2)-3 and b = (√3 - √2)-3, find (a + 1)-1 + (b + 1)-1 .
Answer» a = (\(\sqrt3 + \sqrt2\))^-3 and b = (\(\sqrt3 - \sqrt2\))^-3 Now (a + 1)^-1 + (b + 1)^-1 = \(\frac1{a+1}+\frac1{b+1}=\frac{a+b+2}{(a+1)(b+1)}\) \(\therefore\) (a + 1)^-1 + (b + 1)^-1 = \(\frac{a+b+2}{ab+a+b+1}\)-----(1) Now, ab = (\(\sqrt3 + \sqrt2\))^-3 (\(\sqrt3 - \sqrt2\))^-3 = ((\(\sqrt3 + \sqrt2\))(\(\sqrt3 - \sqrt2\)))^-3 (\(\because\) a^mb^m = (ab)^m) = ((√3)² - (√2)²)^-3(\(\because\) (a + b) (a - b) = a² - b²) = (3 - 2)^-3 = 1^-3 = \(\frac1{1^3}=1\) \(\therefore\) (a + 1)^-1 + (b + 1)^-1 = \(\frac{a+b+2}{1 + a + b+1}\) (From 1) = \(\frac{a+b+2}{a + b + 2}=1\) Hence, (a + 1)^-1 + (b + 1)^-1 = 1

14.

If a = (√3 + √2)-3 and b = (√3 - √2)-3, find (a + 1)-1 + (b + 1)-1 .

Answer»

a = (\(\sqrt3 + \sqrt2\))^-3 and b = (\(\sqrt3 - \sqrt2\))^-3

Now (a + 1)^-1 + (b + 1)^-1 = \(\frac1{a+1}+\frac1{b+1}=\frac{a+b+2}{(a+1)(b+1)}\)

\(\therefore\) (a + 1)^-1 + (b + 1)^-1 = \(\frac{a+b+2}{ab+a+b+1}\)-----(1)

Now, ab = (\(\sqrt3 + \sqrt2\))^-3 (\(\sqrt3 - \sqrt2\))^-3

= ((\(\sqrt3 + \sqrt2\))(\(\sqrt3 - \sqrt2\)))^-3 (\(\because\) a^mb^m = (ab)^m)

= ((√3)² - (√2)²)^-3(\(\because\) (a + b) (a - b) = a² - b²)

= (3 - 2)^-3 = 1^-3 = \(\frac1{1^3}=1\)

\(\therefore\) (a + 1)^-1 + (b + 1)^-1 = \(\frac{a+b+2}{1 + a + b+1}\) (From 1)

= \(\frac{a+b+2}{a + b + 2}=1\)

Hence, (a + 1)^-1 + (b + 1)^-1 = 1

15.	In ∆ABC right angled at B, if tan A= √3, then cos A cos C- sin A sin C = (a) -1(b) 0(c) 1(d) √3/2
Answer» Correct answer is: (b) 0 tan A= √3 = tan 60° so ∠A=60°, Hence ∠C = 30°. So cos A cos C- sin A sin C = (1/2)x (√3/2) - (√3/2)x (1/2) =0

15.

In ∆ABC right angled at B, if tan A= √3, then cos A cos C- sin A sin C = (a) -1(b) 0(c) 1(d) √3/2

Answer»

Correct answer is: (b) 0

tan A= √3 = tan 60° so ∠A=60°, Hence ∠C = 30°.

If a ∶ b = 4 ∶ 7 and b ∶ c = 9 ∶ 4 then find the a ∶ b ∶ c.1. 36 ∶ 63 ∶ 282. 24 ∶ 35 ∶ 143. 40 ∶ 15 ∶ 174. 45 ∶ 35 ∶ 63

Answer» Correct Answer - Option 1 : 36 ∶ 63 ∶ 28

Given:

a ∶ b = 4 ∶ 7

b ∶ c = 9 ∶ 4

Calculations:

Making the ratio of b in both the condition as equal

a	b	c
4 × 9 = 36	7 × 9 = 63
	9 × 7 = 63	4 × 7 = 28

The ratio of a, b and c = 36 ∶ 63 ∶ 28

∴ a ∶ b ∶ c is 36 ∶ 63 ∶ 28

20.	Consider the following statement:"If the diagonals of a quadrilateral bisect each other, then the quadrilateral is a parallelogram."This statement is a/an1. definition2. theorem3. axiom4. proposition
Answer» Correct Answer - Option 2 : theorem If the diagonals of a quadrilateral bisect each other, then the quadrilateral is a parallelogram. This statement is a theorem. Theorem is said to be proposition that is not self-evident but that can be proved from accepted premises and so is established as a law or principle. There are many properties of a parallelogram. We draw a parallelogram and draw both its diagonals intersecting at the point. Measure the lengths of these lines. We observe that the mid-point of the diagonals. Repeat this activity with some more parallelograms. Each time we will find that the mid-point of both the diagonal. We can use the previous concept like length, mid-points etc. Hence we can prove this theorem by accepted premises.
