If x+y=12 and xy=27 then what is (x+y)^2 and x^2+y^2 |
|
Answer» Answer: ( X + y )² = 144 x² + y² = 142 Step-by-step EXPLANATION: Given, x + y = 12 xy = 1 To find : - 1. ( x + y )² 2. x² + y² 1. ( x + y )² = 12² = 144 2. ( x + y )² Formula / Identify : - ( a + B )² = a² + b² + 2ab Here, a = x b = y ( x + y )² = x² + y² + 2ab x² + y² = ( x + y )² - 2ab = 144 - 2 ( 1 ) = 144 - 2 x² + y² = 142 |

|
Answer» Question :
Solution :
We know That - CSA of cylinder = 2πrh Volume of cylinder = πr²h ATQ , πr²h / 2πrh = 1520 / 440 r² / 2 = = 1520 / 440 r ²= 1520×2/ 440 r²= 1520/220 r= √1520/220 BUT WE ARE GIVEN THAT πr²h = 1520 22/7 ×(√1520/440)²×H = 1520 22/7×1520×440× h = 1520 h = 7/ 22×440 h = 0 .007 m |

7 The simple interest on a certain sum for 3 1 by 2 at 7% p.a. is rupee 225 more than the simple interest onthe same sum for 4 years at 5% p.a. Find the sum. |
|
Answer» Step-by-step explanation: Let the SUM be x case (i) Principle = x, Rate = 7%, time = 3.5 yrs Interest = \frac{PTR}{100} 100 PTR
= \frac{x (7)(3.5)}{100} 100 x(7)(3.5)
= \frac{24.5x}{100} 100 24.5x
case (ii) Principle = x, Rate = 5%, time = 4 yrs Interest = \frac{PTR}{100} 100 PTR
= \frac{x (5)(4)}{100} 100 x(5)(4)
= \frac{20x}{100} 100 20x
given that, the SIMPLE interest for case (i) is Rs 225 more than the simple interest for case (ii) \frac{24.5x}{100} - \frac{20x}{100} = 225 100 24.5x
− 100 20x
=225 \frac{4.5x}{100} 100 4.5x
= 225 x = \frac{22500}{4.5} 4.5 22500
x = 5000 The sum = Rs 5000 |

The eighth term of a linear sequence is 26. The term-to-term rule is 'add 3Work out the fourth term of the sequence.Explain the method you used to solve this problem. |
|
Answer» Answer: The FOURTH term of the sequence is 14. The METHOD used to solve this is Arithmetic Progression (AP). Step-by-step EXPLANATION: In the AP, d = 3 a₈ = 26 ⇒ a + 7d = 26 [aₙ = a + (n-1)×d] ⇒ a + (7 × 3) = 26 ⇒ a + 21 = 26 ⇒ a = 5 ∴ a₄ = a + 3d = 5 + (3 × 3) = 5 + 9 = 14 |
