7.	Find g(x),ig p(x)=x²+5x+13 wheb q(x(=(x+2) and r(x)=7
Answer» ANSWER :- Given :- p(X) = x² + 5x + 13 Q(x) = x + 2 r(x) = 7 To Find :- g(x) Solution :- We know that, → p(x) = g(x) × q(x) + r(x) Substituting the values in FORMULA :- → x² + 5x + 13 = ( x + 2 ) × g(x) + 7 → x² + 5x + 13 - 7 = ( x + 2 ) × g(x) → x² + 5x + 6 = ( x + 2 ) × g(x) → x² + 2x + 3x + 6 = ( x + 2 ) × g(x) → x ( x + 2 ) + 3 ( x + 2 ) = ( x + 2 ) × g(x) → ( x + 3 ) ( x + 2 ) = ( x + 2 ) × g(x) → ( x + 3 ) ( x + 2 ) / ( x + 2 ) = g(x) → g(x) = x + 3 Value of g(x) = x + 3

7.

Find g(x),ig p(x)=x²+5x+13 wheb q(x(=(x+2) and r(x)=7

Answer»

ANSWER :-

Given :-

p(X) = x² + 5x + 13
Q(x) = x + 2
r(x) = 7

To Find :-

g(x)

Solution :-

We know that,

→ p(x) = g(x) × q(x) + r(x)

Substituting the values in FORMULA :-

→ x² + 5x + 13 = ( x + 2 ) × g(x) + 7

→ x² + 5x + 13 - 7 = ( x + 2 ) × g(x)

→ x² + 5x + 6 = ( x + 2 ) × g(x)

→ x² + 2x + 3x + 6 = ( x + 2 ) × g(x)

→ x ( x + 2 ) + 3 ( x + 2 ) = ( x + 2 ) × g(x)

→ ( x + 3 ) ( x + 2 ) = ( x + 2 ) × g(x)

→ ( x + 3 ) ( x + 2 ) / ( x + 2 ) = g(x)

→ g(x) = x + 3

Value of g(x) = x + 3

36.	N(A)=n then find the number of elements in power set A
Answer» Answer: If a non-empty SET A contains n elements, then its power set contains 2 n elements. This can be PROVED using mathematical induction. Base Case: suppose ∣A∣=0⟹A=ϕ. But, empty set is only subset of itself. So, ∣P(A)∣=1=2 0 . Now, suppose ∣A∣=n. By induction hypothesis, we know that ∣P(A)∣=2 n ⟶1 Let B be a set with (n+1) elements, B=A∪{a} Now, there are 2 kinds of subsets of B: those that include ′ a ′ and those that don't. The first ONES are EXACTLY the subsets of X which do not contain ′ a ′ and there are 2 n of them. The second one are of the form C∪{a}, where C∈P(A). since there are 2 n possible choices for C, there must be exactly 2 n subsets of B of which ′ a ′ is an element. ∴∣P(B)∣=2 n +2 n =2 n+1 . so, if set has n elements, then power set has 2 n elements. Hence proved. $please mark this answer as a brainliest.$ brainly.in/question/39427321

The first ONES are EXACTLY the subsets of X which do not contain

′

a

′

and there are 2

n

of them.

The second one are of the form C∪{a}, where C∈P(A). since there are 2

n

possible choices for C, there must be exactly 2

n

subsets of B of which

′

a

′

is an element.

∴∣P(B)∣=2

n

n

so, if set has n elements, then power set has 2

Prove it...please prove the question step by step

Answer»

cos6x = 32cos⁶x - 48 cos⁴x + 18 cos²x - 1

LHS ↓

cos6x = cos(2×3x)

cos2x = 2cos²x - 1

cos6x = 2cos²(3x) −1

cos6x = 2 (cos 3x)² − 1

cos3x = 4cos³x − 3cosx

cos6x = 2 (4cos³x − 3cosx)² –1

cos6x = 2(16cos⁶x – 24cos⁴x + 9cos²x) – 1

cos6x = 32cos⁶x −48cos⁴x + 18cos²x – 1

RHS ↑

LHS = RHS

Answer» Answer: 2. 5.5cm Step-by-step explanation: IN ENGLISH, GIVEN: PQRS is a RECTANGLE which Diagonals bisects each other at point O. &Diagonal PR = 11cm Solution: Diagonals of a rectangle are ALWAYS equal. so, Diagonal PR = Diagonal SQ = 11cm We know that both diagonals of a rectangle bisect each other into two equal parts. Hence, OS = Diagonal SQ/2 = 11/2 = 5.5cm ANS. IN MARATHI, दिलेः PQRS एक आयत आहे जे कर्ण बिंदू O वर एकमेकांना विभक्त करते आणि कर्ण PR = 11 सेमी उपाय: आयताचे कर्ण नेहमी समान असतात. तर, कर्ण PR = कर्ण SQ = 11 सेमी आम्हाला माहित आहे की आयताचे दोन्ही कर्ण एकमेकांना दोन समान भागांमध्ये विभाजित करतात. म्हणून, OS = कर्ण SQ / 2 = 11/2 = 5.5 सेमी ANS.

आयत PQRS चे कर्ण परस्परांना 'O' बिंदूत छेदतात. जर कर्ण PR ची लांबी 11 सेमी असेल तर l (OS ) = ? 1️⃣ 11 सेमी 2️⃣ 5.5 सेमी 3️⃣ 22 सेमी 4️⃣ 5 सेमी

Answer»

Answer:

2. 5.5cm

Step-by-step explanation:

IN ENGLISH,

GIVEN: PQRS is a RECTANGLE which Diagonals bisects each other at point O. &Diagonal PR = 11cm

Solution:

Diagonals of a rectangle are ALWAYS equal.

so, Diagonal PR = Diagonal SQ = 11cm

We know that both diagonals of a rectangle bisect each other into two equal parts.

Hence, OS = Diagonal SQ/2

= 11/2 = 5.5cm ANS.

IN MARATHI,

दिलेः PQRS एक आयत आहे जे कर्ण बिंदू O वर एकमेकांना विभक्त करते आणि कर्ण PR = 11 सेमी

उपाय: आयताचे कर्ण नेहमी समान असतात.

तर, कर्ण PR = कर्ण SQ = 11 सेमी

आम्हाला माहित आहे की आयताचे दोन्ही कर्ण एकमेकांना दोन समान भागांमध्ये विभाजित करतात.

म्हणून, OS = कर्ण SQ / 2

= 11/2 = 5.5 सेमी ANS.
