Three vertices of a square are p (-1,-9), Q (3,-1), R(-5,3). Find the coordinates of vertex S. |
Answer» Mid Point Formula→ (x₁+ x₂)/2 , (y₁ + y₂)/2 = (Coordinate of mid point) → (- 1 - 5)/2, (- 9 + 3)/2 = LHS → - 3, - 3 = LHS → (3 + x)/2, (- 1 + y)/2 = RHS Since, in a SQUARE diagnonals are EQUAL and bisect each other. → (3 + x)/2, (-1 + y)/2 = - 3, - 3 → (3 + x)/2 = - 3 and (-1 + y)/2 = - 3 → 3 + x = - 6 and - 1 + y = - 6 → x = - 9 and y = - 5 Hence, Coordinate of VERTEX S is - 9, - 5. Answer : (- 9, - 5) |

Chris gayle has a legacy of hitting sixes in his innings. He loves to hit sixes. Now in a particular match, he already know that he will face total of (n + 1) balls which means that he will get out on (n + 1)th ball. So he has decided to hit sixes in each of the initial n balls. He will require some power pi to hit a six on the ball. |

This question is one of the toughest question which include high thinking skills so answer615 + x^2 = 2^yfind x and y for the following |
|
Answer» Answer: x=59,-59 y=12 Step-by-step explanation: 615 + x2 = 2y First we know x ≥ 0, so 615 ≤ 2y, and so y > 9 since 29 = 512. In order for the two sides to be equal, the last digit of each side must be equal. So let’s start by analyzing the last digit of 615 + x2. Last digit of x – 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 x2 – 0, 1, 4, 9, 6, 5, 6, 9, 4, 1 From the last calculation we can add 5 to get the last digit of 615 + x2: Last digit of 615 + x2 – 5, 6, 9, 4, 1, 0, 1, 4, 9, 6 The powers of 2 have a pattern. The last digit cycles every 4 terms as 2, 4, 8, 6 starting with y = 1, 2, 3, 4, … In order that the last digits are equal, we want 615 + x2 to have an even last digit. Hence we must have a last digit of 4 or 6. The last digit of 4 or 6 only occurs when y is 2, 4, …, or when y is even. So we have established that y is even, or equal to 2N for some integer N. How does this help us? It is actually the entire key to this problem! We can now write: 615 + x2 = 2y 615 + x2 = 22n 615 = 22n – x2 Now we can do a neat algebra trick. The right hand side is a difference of two square numbers, so we can use the formula A2 – b2 = (a + b)(a – b). So we get: 615 = 22n – x2 615 = (2n + x)(2n – x) We now consider the factors of 615. Since 615 = 3 × 5 × 41, there are only a few possibilities: 615 = 1 × 615 615 = 3 × 205 615 = 5 × 123 615 = 15 × 41 We can further limit the possibilities because if the two factors are (2n + x) and (2n – x), then we have sum of factors (2n + x) + (2n – x) = 2(2n) = 2n+1 So we need the sum of the factors to be a power of 2. 615 = 1 × 615, sum(factors) = 616 615 = 3 × 205, sum(factors) = 208 615 = 5 × 123, sum(factors) = 128 615 = 15 × 41, sum(factors) = 56 The only sum that is a power of 2 is 128. So we have 128 = 27 = 2n+1, which means n = 6 and so y = 2n = 12. How to solve for x? An easy way is to use the difference of factors: difference of factors (2n + x) – (2n – x) = 2x or (2n – x) – (2n + x) = -2x So we have 123 – 5 = 118 = 2x, MEANING x = 59; or we have 123 – 5 = 118 = -2x, meaning x = -59. And we’ve proven the only integer solutions are (x = 59, y = 12) and (x = -59, y = 12). We can also verify: 615 + 59^2 = 4096 = 2^12 615 + (-59)^2 = 4096 = 2^12 |

Make a chart on formulas of mensuration with their figures |
|
Answer» Answer: Mensuration FORMULAS Mensuration is the branch of mathematics which deals with the study of Geometric shapes, their area, volume and related parameters. Some IMPORTANT mensuration formulas are: 1. Area of rectangle (A) = length(l) × Breath(b) 
2. Perimeter of a rectangle (P) = 2 × (Length(l) + Breath(b)) 
3. Area of a square (A) = Length (l) × Length (l) 
4. Perimeter of a square (P) = 4 × Length (l) 
5. Area of a parallelogram(A) = Length(l) × Height(h)  
6. Perimeter of a parallelogram (P) = 2 × (length(l) + Breadth(b)) 
7. Area of a TRIANGLE (A) = (Base(b) × Height(b)) / 2   And for a triangle with sides measuring “a” , “b” and “c” , Perimeter = a+b+c and s = semi perimeter = perimeter / 2 = (a+b+c)/2 And also: Area of triangle =  This formulas is also knows as “Heron’s FORMULA”.
8. Area of triangle(A) = Where A, B and C are the vertex and angle A , B , C are respective angles of triangles and a , b , c are the respective opposite sides of the angles as shown in figure below: TwitterStumbleUponFacebookLink To Us घर | जीव विज्ञान | रसायन विज्ञान | पृथ्वी | प्रोजेक्ट्स | भौतिकी | अंतरिक्ष| शब्दकोश विज्ञापन छिपाएँ विज्ञापन के बारे में माहवारी के सूत्र मेंसुरेशन गणित की वह शाखा है जो ज्यामितीय आकृतियों, उनके क्षेत्र, आयतन और संबंधित मापदंडों के अध्ययन से संबंधित है। कुछ महत्वपूर्ण माहवारी सूत्र हैं: 1. आयत का क्षेत्रफल (A) = लंबाई (l) × सांस (b)  2. एक आयत की परिधि (P) = 2 × (लंबाई (l) + सांस (b))  3. एक वर्ग का क्षेत्रफल (A) = लंबाई (l) × लंबाई (l)  4. एक वर्ग की परिधि (P) = 4 × लंबाई (l)  5. एक समांतर चतुर्भुज का क्षेत्रफल (A) = लंबाई (l) × ऊँचाई (h)   6. एक समांतर चतुर्भुज की परिधि (P) = 2 × (लंबाई (l) + चौड़ाई (b))  7. एक त्रिभुज का क्षेत्रफल (A) = (बेस (b) × ऊँचाई (b)) / 2  |
