Activity iLet A = {r|x € N,w |
|
Answer» Answer: This appears to be a way of finding a number a , which when ADDED to x 2 − 16 x ( x + b ) 2
We can write x 2 − 16 x + a = ( x + b ) 2 as x 2 − 16 x + a = x 2 + 2 b x + b 2
Now comparing COEFFICIENTS of SIMILAR terms 2 b = − 16 or b = − 8
and a = b 2 = ( − 8 ) 2 = 64 |

|
Answer» Step-by-step explanation: (i) 6 : 8 and 12 : 16 6 : 8 = 6/8 = 3/4 12 : 16 = 12/16 = 3/4 Thus, the ratios 6 : 8 and 12 : 16 are equal. Therefore, they form a proportion.
24 : 28 = 24/28 = 6/7 36 : 48 = 36/48 = 3/4 Thus, the ratios 24 : 28 and 36 : 48 are unequal. Therefore, they do not form a proportion. |

3x+2y=5 , 2x-3y=12 find the value of x and y |
Answer» Given :
To FIND :The value of x and y. Solution :Analysis :Here we have to solve the linear equations simultaneously. We have to solve it by elimination method. Explanation :3x + 2y = 5 ------(EQ.(i)) 2x - 3y = 12 ------(eq.(ii)) Multiplying eq.(i) with 2 and eq.(ii) with 3, 6x + 4y = 10 ------(eq.(iii)) 6x - 9Y = 36 ------(eq.(iv)) Subtracting eq.(iv) from eq.(iii), ⇒ 4y + 9y = -26 ⇒ 13y = -26 ⇒ y = -26/13 ⇒ y = -2 ∴ y = -2.
⇒ 3x + 2y = 5 ⇒ 3x + 2(-2) = 5 ⇒ 3x + (-4) = 5 ⇒ 3x - 4 = 5 ⇒ 3x = 5 + 4 ⇒ 3x = 9 ⇒ x = 9/3 ⇒ x = 3 ∴ x = 3. The value of x is 3 and y is -2. |

X²+6x+1=0 using quadratic formula |
Answer» Required Answer:-Given:
To Find:Solution:Given equation, ⟹ x² + 6x + 1 = 0 Here,
Roots of a quadratic equation are given by the formula, ⟹ x₁,₂ = (-b ± √∆)/2a Where, ⟹ ∆ = b² - 4ac (Also CALLED DISCRIMINANT) Calculate the value of discriminant, b² - 4ac = 6² - 4 × 1 × 1 = 36 - 4 = 32 Therefore, ⟹ x₁,₂ = (-6 ±√32)/2 ⟹ x₁,₂ = (-6 ± 4√2)/2 ⟹ x₁,₂ = -3 ± 2√2 ⟹ x = -3 + 2√2 and -3 - 2√2 Hence, the roots of the given equation are -3 + 2√2 and -3 - 2√2.

9.2. Prove that V2+ V3 is an irrational number |
|
Answer» Step-by-step explanation: Given :-√2+√3 To Prove :-Prove that √2+√3 is an irrational number? Solution:-Given number =√2+√3 Let us ASSUME that √2+√3 is a RATIONAL number Then it must be in the form of p/q where p and q are integers and q≠0 =>√2+√3=a/b,where a and b are co-primes =>√3=(a/b)-√2 On squaring both sides then =>(√3)²=[(a/b)-√2]² =>3=(a/b)²-2(a/b)(√2)+(√2)² =>3=(a²/b²) - 2√2a/b+2 =>(a²/b²)-2√2a/b=3-2 =>(a²/b²)-2√2a/b=1 =>2√2a/b=(a²/b²)-1 =>2√2a/b=(a²-b²)/b² =>2√2=(a²-b²)(b)/ab² =>2√2=(a²-b²)/ab =>√2=(a2-b²)/(2AB) √2 is the form of a/b =>√2 is a rational number. But √2 is not a rational number . This is contradiction to our assumption. √2+√3 is not a rational number. √2+√3 is an irrational number. Hence, Proved Used method:-Method of Contradiction (Indirect method) Note :-SUM of any two irrational Numbers is also an irrational number. √2=1.414... √3=1.732... √2+√3=1.414...+1.732...=3.146...is an irrational number. |
