Answer»

Answer:

base angles are 70 and 70

Step-by-step EXPLANATION:

so ISOCELES tringle

so, 2 sides are equal 2x

bertex angle is 40 degree

so, base side = y , sex,

2x= 180-40

2x= 140

x= 70

Answer» Answer: a.(y + 4)^3 = y^3+4^3+3(y)(4)(y+4) = y^3+64+12y(y+4) = y^3+64+12y^2+48y = y^3+12y^2+48y+64 b.(4y – 2)^3 = (4y)^3-(2)^3-3(4y)(2)(4y-2) = 64y^3-8-24y(4y-2) = 64y^3-8-96y^2+48y = 64y^3-96y^2+48y-8 c.(y – 6)^3 = y^3-6^3-3(y)(6)(y-6) =y^3-216-18y(y-6) = y^3-216-18y^2+108y =y^3-18y^2+108y-216 d.(6y + 1)^3 = (6y)^3+1^3+3(6y)(1)(6y+1) = 216y^3+1+18y(6y+1) = 216y^3+1+108y^2+18y = 216y^3+108y^2+18y+1

7.

Factorise: a.(y + 4)^3 b.(4y – 2)^3c.(y – 6)^3 d.(6y + 1)^3

Answer»

Answer: a.(y + 4)^3 = y^3+4^3+3(y)(4)(y+4)

= y^3+64+12y(y+4)

= y^3+64+12y^2+48y

= y^3+12y^2+48y+64

b.(4y – 2)^3 = (4y)^3-(2)^3-3(4y)(2)(4y-2)

= 64y^3-8-24y(4y-2)

= 64y^3-8-96y^2+48y

= 64y^3-96y^2+48y-8

c.(y – 6)^3 = y^3-6^3-3(y)(6)(y-6)

=y^3-216-18y(y-6)

= y^3-216-18y^2+108y

=y^3-18y^2+108y-216

d.(6y + 1)^3 = (6y)^3+1^3+3(6y)(1)(6y+1)

= 216y^3+1+18y(6y+1)

= 216y^3+1+108y^2+18y

= 216y^3+108y^2+18y+1

19.	It cosec thita = 13/12find the value of cot thita+tan thita
Answer» Answer: 169/60 Step-by-step EXPLANATION: For simplicity, let's assume angle theta to be equal to angle alpha. Now, it's given that, $\csc( \alpha ) = \frac{13}{12}$ To find the value of , $\cot( \alpha ) + \tan( \alpha )$ From the QUESTION, we have, $\csc( \alpha ) = \frac{13}{12}$ But, we KNOW that, [email PROTECTED] = 1/[email protected] Therefore, we will get, $= > \frac{1}{ \sin( \alpha ) } = \frac{13}{12} \\ \\ = > \sin( \alpha ) = \frac{12}{13}$ Now, we know that, [email protected] = √(1-sin^[email protected]) Therefore, we will get, $= > \cos( \alpha ) = \sqrt{1 - {( \frac{12}{13} )}^{2} } \\ \\ = > \cos( \alpha ) = \sqrt{1 - \frac{144}{169} } \\ \\ = > \cos( \alpha ) = \sqrt{ \frac{169 - 144}{169} } \\ \\ = > \cos( \alpha ) = \sqrt{ \frac{25}{169} } \\ \\ = > \cos( \alpha ) = \frac{5}{13}$ Therefore, we will get, $= > \tan( \alpha ) = \frac{ \sin( \alpha ) }{ \cos( \alpha ) } \\ \\ = > \tan( \alpha ) = \frac{ \frac{12}{13} }{ \frac{5}{13} } \\ \\ = > \tan( \alpha ) = \frac{12}{5}$ Now, we know that, [email protected] = 1/[email protected] Therefore, we will get, $= > \cot( \alpha ) = \frac{5}{12}$ Therefore, we will get, $= > \tan( \alpha ) + \cot( \alpha ) = \frac{5}{12} + \frac{12}{5} \\ \\ = > \tan( \alpha ) + \cot( \alpha ) = \frac{25 + 144}{60} \\ \\ = > \tan( \alpha ) + \cot( \alpha ) = \frac{169}{60}$ HENCE, the required value id 169/60.

It cosec thita = 13/12find the value of cot thita+tan thita

Answer»

Answer:

169/60

Step-by-step EXPLANATION:

For simplicity, let's assume angle theta to be equal to angle alpha.

Now, it's given that,

$\csc( \alpha ) = \frac{13}{12}$

To find the value of ,

$\cot( \alpha ) + \tan( \alpha )$

From the QUESTION, we have,

$\csc( \alpha ) = \frac{13}{12}$

But, we KNOW that,

[email PROTECTED] = 1/[email protected]

Therefore, we will get,

$= > \frac{1}{ \sin( \alpha ) } = \frac{13}{12} \\ \\ = > \sin( \alpha ) = \frac{12}{13}$

Now, we know that,

[email protected] = √(1-sin^[email protected])

Therefore, we will get,

$= > \cos( \alpha ) = \sqrt{1 - {( \frac{12}{13} )}^{2} } \\ \\ = > \cos( \alpha ) = \sqrt{1 - \frac{144}{169} } \\ \\ = > \cos( \alpha ) = \sqrt{ \frac{169 - 144}{169} } \\ \\ = > \cos( \alpha ) = \sqrt{ \frac{25}{169} } \\ \\ = > \cos( \alpha ) = \frac{5}{13}$

Therefore, we will get,

$= > \tan( \alpha ) = \frac{ \sin( \alpha ) }{ \cos( \alpha ) } \\ \\ = > \tan( \alpha ) = \frac{ \frac{12}{13} }{ \frac{5}{13} } \\ \\ = > \tan( \alpha ) = \frac{12}{5}$

Now, we know that,

[email protected] = 1/[email protected]

Therefore, we will get,

$= > \cot( \alpha ) = \frac{5}{12}$

Therefore, we will get,

$= > \tan( \alpha ) + \cot( \alpha ) = \frac{5}{12} + \frac{12}{5} \\ \\ = > \tan( \alpha ) + \cot( \alpha ) = \frac{25 + 144}{60} \\ \\ = > \tan( \alpha ) + \cot( \alpha ) = \frac{169}{60}$

HENCE, the required value id 169/60.

32.	If P and Q are finite sets where n(Q) = 90 and n(P⋂Q) = 30 , n(P⋃Q) = 108 find n(P-Q):
Answer» ANSWER: we have a formula N(PUQ) = n(P) + n(Q) - n(P⋂Q) from that we get 108 = x + 90 - 30 108 + 30 = x + 90 138 - 90 = x x = 48 therefore n(P) = 48 we have another formula n(P-Q) = n(P) - n(P⋂Q) from that n(P-Q) = 48 - 30 n(P-Q) = 18 THEREFORE n(P-Q) = 18

32.

If P and Q are finite sets where n(Q) = 90 and n(P⋂Q) = 30 , n(P⋃Q) = 108 find n(P-Q):

Answer»

ANSWER:

we have a formula

N(PUQ) = n(P) + n(Q) - n(P⋂Q)

from that we get

108 = x + 90 - 30

108 + 30 = x + 90

138 - 90 = x

x = 48

therefore n(P) = 48

we have another formula

n(P-Q) = n(P) - n(P⋂Q)

from that

n(P-Q) = 48 - 30

n(P-Q) = 18

THEREFORE n(P-Q) = 18

33.	Why subtraction is important to write a number in Roman Numerals? If you are asked to exclude subtraction from Roman Numeral System what changes will you suggest? How will you write 49, 495 and 1999 in this case?
Answer» If subtraction has to be removed from roman numerals, then ONE main change that should take PLACE is that a number should be allowed to be repeated more than 3 times. If this change TAKES place then it will be EASY to write any number in the form of roman numerals. 49= XXXXVIIII 495= CCCCLXXXXV 1999= MDCCCCLXXXVIIII Hope it helps!!!!

The presidents, vice presidents, and secretary-treasurers from each of four classes are eligible for an all-school council. How many ways can four officers be chosen from these representatives? How many ways can they be chosen if the president must be selected from the sitting presidents, the vice president from the sitting vice presidents, the secretary from the sitting secretary-treasurers, and the treasurer from everybody who’s left?

Answer»

Given : The PRESIDENTS, vice presidents, and secretary-treasurers from each of four classes are eligible for an all-school council. How many ways can four officers be chosen from these representatives

To find : How many ways can four officers be chosen from these representatives

Solution:

The presidents, vice presidents, and secretary-treasurers from each of four classes

4 Presidents , 4 vice presidents , 4 Secretary , 4 Treasures

HENCE Total = 4 * 4 = 16

four officers be chosen from these representatives = ¹⁶C₄ = 1820 ways

2nd case :

president must be selected from the sitting presidents = ⁴C₁ = 4 ways

vice president must be selected from the sitting vice presidents = ⁴C₁ = 4 ways

the secretary from the sitting secretary-treasurers = ⁸C₁ = 8 ways

3 PEOPLE Selected so remaining = 16 -3 = 3

treasurer can be selected in 13 Ways

Total Ways = 4 * 4 * 8 * 13 = 1664

Trace the curve y2 (x2-1)= 2x-1 with solution

Answer»

Given : Curve y² (x² - 1) = 2x - 1

To find : Trace the Curve

Solution:

y² (x² - 1) = 2x - 1

=> y² = (2x - 1)/(x² - 1)

x² - 1 ≠ 0

y = - when 2x - 1 = 0 => x = 1/2

x = 1/2 x = - 1, 1

y² ≥ 0

x < - 1 2x - 1 is - ve & x² - 1 is + ve hence y² - ve so no solution

for x < - 1

for -1 < x < 1/2 2x - 1 is - ve & x² - 1 is - ve hence y² + ve

so y exist for -1 < x < 1/2

for 1/2 < x < 1 , 2x - 1 is + ve & x² - 1 is - ve hence y² - ve so no solution

for 1/2 < x < 1

for x > 1 2x - 1 is + ve & x² - 1 is + ve hence y² + ve

so y exist for x > 1

x - Domain

-1 < x < 1/2 , x > 1
