Factorise completely x⁴-16

Answer»

Question :

Factorise $\mathtt{x^4-16}$

$\begin {gathered} \end {gathered}$

Answer :

$\mathtt{x^4 - 16 = (x^2 + 4)(x+2)(x-2)}$

$\begin {gathered} \end {gathered}$

STEP - by - Step EXPLANATION :

We have,

$\begin {aligned} (1) \ \bold {x^4 - 16} &\Rightarrow [(x^2)^2 - 4^2]\\\\&[\text{Using <klux>IDENTITY</klux> $a^2 - b^2 = (a + b)(a- b)$}]\\\\&= \bf (x^2 + 4)(x^2 - 4)\end {aligned}$

$\begin {gathered} \end {gathered}$

This can further be Factorised by using the Same Identity GIVEN above . . .

$\begin {aligned} (2) \ \bold {(x^2 + 4)(x^2 - 4)} &\Rightarrow \Big [(x^2 + 4)[(x)^2 - 2^2]\Big ]\\\\&= \bf \Big [(x^2 + 4)(x + 2)(x - 2)\Big ] \end {aligned}$

24.	the compound interest calculated yearly on a certain sum of money for the second year is rs 1650 and for the third year is rs 1815 . Calculate the rate of interest and the sum of money
Answer» Answer: Answer Correct option is A 12000 C.I. for the third year = Rs. 1,452. C.I. for the SECOND year = Rs. 1,320 ∴ S.I on Rs. 1,320 for ONE year = Rs. 1,452− Rs. 1,320= Rs. 132. RATE of interest = 1,320 132×100 =10%. Let the ORIGINAL MONEY be Rs. P. Amount after 2 year − amount after one year =C.I. for second year. P(1+ 100 10 ) 2 −P(1+ 100 10 )=1,320 P[( 100 110 ) 2 − 100 110 ]=1,320 ⇒P[( 10 11 ) 2 − 10 11 ]=1,320⇒P( 100 121 − 10 11 )= Rs. 1,320 ⇒P× 100 11 =Rs.1,320⇒P= 11 1,320×100 = Rs. 12,000 ∴ Rate of interest =10% and Original sum of money = Rs. 12,000

Answer» Answer: B) 24 hours. Step-by-step explanation: John stitches a TROUSER in 4 hours => John stitches 1/4 of a trouser in 1 hour. Jack stitches a trouser in 3 hours => Jack stitches 1/3 of a trouser in 1 hour. So, both WOULD STITCH 1/4 + 1/3 = 3/12 + 4/12 = 7/12 of a trouser in 1 hour. If they both have to stitch 14 trousers together, it would take (14 ÷ 7/12) hours = (14 × 12/7) hours = 24 hours.

Answer»

Answer:

B) 24 hours.

Step-by-step explanation:

John stitches a TROUSER in 4 hours

=> John stitches 1/4 of a trouser in 1 hour.

Jack stitches a trouser in 3 hours

=> Jack stitches 1/3 of a trouser in 1 hour.

So, both WOULD STITCH 1/4 + 1/3 = 3/12 + 4/12 = 7/12 of a trouser in 1 hour.

If they both have to stitch 14 trousers together, it would take (14 ÷ 7/12) hours = (14 × 12/7) hours = 24 hours.

37.	Question:-(Refer to the attachment).________... Answer with proper explanation required.
Answer» Given, AB = AC AD is an angle bisector AD = 2√2 cm Since AB = AC, opposite ANGLES are ought to be equal. $\implies$ ABD = ACD From Angle Sum Properly, A + B + C = 180° $\implies$ 90° + ABD + ACD = 180° $\implies$ 2ABD = 90° $\implies$ ABD = ACD = 45° (ABC = ACB = 45°) Now, tan(ABD) = AD/BD $\longrightarrow$ tan45° = 2√2/BD $\longrightarrow$ BD = 2√2cm Likewise, CD = 2√2cm. We KNOW that, BC = BD + CD = 4√2cm Now, sin(ABC) = AC/BC $\longrightarrow$ sin45° = AC/4√2 $\longrightarrow$ AC = 4√2/√2 $\longrightarrow$ AC = AB = 4cm For perimeter of ∆ABC, AB + BC + AC $\longrightarrow$ 4 + 4 + 4√2 $\longrightarrow$ (8 + 4√2) cm Thus, the perimeter of ∆ABC is 8 + 4√2 cm.

Question:-(Refer to the attachment).________... Answer with proper explanation required.

Answer»

Given,

AB = AC
AD is an angle bisector
AD = 2√2 cm

Since AB = AC, opposite ANGLES are ought to be equal.

$\implies$ ABD = ACD

From Angle Sum Properly,

A + B + C = 180°

$\implies$ 90° + ABD + ACD = 180°

$\implies$ 2ABD = 90°

$\implies$ ABD = ACD = 45° (ABC = ACB = 45°)

Now,

tan(ABD) = AD/BD

$\longrightarrow$ tan45° = 2√2/BD

$\longrightarrow$ BD = 2√2cm

Likewise, CD = 2√2cm.

We KNOW that, BC = BD + CD = 4√2cm

Now,

sin(ABC) = AC/BC

$\longrightarrow$ sin45° = AC/4√2

$\longrightarrow$ AC = 4√2/√2

$\longrightarrow$ AC = AB = 4cm

For perimeter of ∆ABC,

AB + BC + AC

$\longrightarrow$ 4 + 4 + 4√2

$\longrightarrow$ (8 + 4√2) cm

Thus, the perimeter of ∆ABC is 8 + 4√2 cm.

Amount = Principal+S.I

To FIND amount FIRST we have to find S.I

S.I = P×R×T/100
