6.	Solve: √(3-x)²+(5-7)² - √(4-3)²+(7-5)²
Answer» Answer: For example: x² × x³, 2³ × 2⁵, (-3)² × (-3)⁴ In MULTIPLICATION of EXPONENTS if the BASES are same then we need to add the exponents. Consider the FOLLOWING: 1. 2³ × 2² = (2 × 2 × 2) × (2 × 2) = 23+2 = 2⁵ 2. 3⁴ × 3² = (3 × 3 × 3 × 3) × (3 × 3) = 34+2 = 3⁶

6.

Solve: √(3-x)²+(5-7)² - √(4-3)²+(7-5)²

Answer»

Answer:

For example: x² × x³, 2³ × 2⁵, (-3)² × (-3)⁴

In MULTIPLICATION of EXPONENTS if the BASES are same then we need to add the exponents.

Consider the FOLLOWING:

1. 2³ × 2² = (2 × 2 × 2) × (2 × 2) = 23+2 = 2⁵

2. 3⁴ × 3² = (3 × 3 × 3 × 3) × (3 × 3) = 34+2 = 3⁶

Answer» ANSWER: It is GIVEN that Interest for the FIRST year = 225 Interest for the second year = 240 So the difference = 240 - 225 = 15 Here 15 is the interest on 225 for 1 year (i) Rate = (SI×100)/(P×t) SUBSTITUTING the values =(15×100)/(225×1) So we get = 3 20 =6 3 2 % p.a. (II) We know that Sum=(SI×100)/(R×t) Substituting the values =(225×100)/(20/3×1) It can be written as =(225×100×3)/(20×1) So we get = 225×15 =3375 (iii) Here AMount after second year = 225 + 240 + 3375 = 3840 So the interest for the third year = Prt/100 Substituting the values =(3840×20×1)/(100×3) =256

A sum of money is invested at compound interest payable annually.The interest in two successive year in rs 240. find :-(I) the rate of interest

Answer»

ANSWER:

It is GIVEN that

Interest for the FIRST year = 225

Interest for the second year = 240

So the difference = 240 - 225 = 15

Here 15 is the interest on 225 for 1 year

(i) Rate = (SI×100)/(P×t)

SUBSTITUTING the values

=(15×100)/(225×1)

So we get

=

=6

3

2

% p.a.

(II) We know that

Sum=(SI×100)/(R×t)

Substituting the values

=(225×100)/(20/3×1)

It can be written as

=(225×100×3)/(20×1)

So we get

= 225×15

=3375

(iii) Here

AMount after second year = 225 + 240 + 3375 = 3840

So the interest for the third year = Prt/100

Substituting the values

=(3840×20×1)/(100×3)

=256

In A (-1, 1), B(1, 3) and C(3, a) point and if AB = BC than find a in coordinate geometry

Answer»

$\sf{answer}$

formula required:-

Distance formula :

$d = \sqrt{(x_2 - x_1)^{2} + (y_2 - y_1)^{2} }$

given,

A (-1, 1), B(1, 3) and C(3, a).

to find:-

VALUE of 'a'.

$\sf\underline{solution}$

first we find AB and next BC

in, AB:-

A = (-1,1)

let:- -1 = $\sf{x_1}$

1 = $\sf{y_1}$

B = (1,3)

1 = $\sf{x_2}$

3 = $\sf{y_2}$

.: AB = $\sqrt{(1-(-1))²+(3-1)²}$

= $\sqrt{(2)²+(2)²}$

= $\sqrt{4+4}$

= $\sqrt{8}$

= 2 $\sqrt{2}$

in BC,

B = (1,3)

let

1 = $\sf{x_1}$

3 = $\sf{y_1}$

C = (3,a)

3 = $\sf{x_2}$

a = $\sf{y_2}$

.: BC = $\sqrt{(3-1)²+(a-3)²}$

= $\sqrt{(2)²+(a²-2(a)(3)+(-3)²}$

= $\sqrt{4+a²-6a+9}$

= √a²-6a+13

.: AB = BC

2√2 = √a²-6a+13

squaring on both sides

(2√2)² = (√a²-6a+13)²

4×2 = a²-6a+13

8 = a²-6a+13

a²-6a+13-8= 0

a²-6a+5 = 0

a²-5a-a+5 = 0
