Construct a quadrilateral abcd in which ab=3.5cm bc=6.5cm , angle a=75 degrees degrees, angle b=105 degrees and angle c=120 degree |
|
Answer» Step-by-step explanation: Procedure to DRAW a quadrilateral 1. Draw a line segment of ab = 3.5 cm 2. MEASURE ANGLE 60° from point 'a' by using protractor. 3. According to property of Quadrilateral
∠a + ∠B + ∠c + ∠d = 360° 60° + ∠b + 120° + 75° = 360° ∠b = 105° 4. Measure ∠105° AT point b and draw a line. 5. measure length = 6.5 cm with the help of compass and cut the arc at the line from point 'b'. you will get point 'c' 6. at point 'c' measure ∠120° and draw a line, which cuts the line drawn from point 'a'. 7. measure the angle 'd', you will find that it measures 75° Read more on Brainly.in - brainly.in/question/1842485#readmore |

If 1/5 and – 2 are respectively product and sum of the zeroes of a quadratic polynomial. Find the polynomial. This is a grade 10 NCERT problem. |
|
Answer» GIVEN: PRODUCT of the zeroes = 1/5 Sum of zeroes = -2 TO FIND: The quadratic polynomial SOLUTION: We know that, The standard FORM of quadratic polynomial is, k {x² - (sum of zeroes)X + product of zeroes} Where, k ≠0 => k {x² - (-2)x + (1/5) => k {x² + 2x + 1/5} When k = 5 => 5(x² + 2x + 1/5) => 5x² + 10x + 1 Therefore, the required polynomial is 5x² + 10x + 1. |

What is Prime number theorem |
|
Answer» Answer: Step-by-step explanation: Prime number theorem, formula that gives an approximate value for the number of primes less than or equal to any given positive real number x. The usual notation for this number is π(x), so that π(2) = 1, π(3.5) = 2, and π(10) = 4. The prime number theorem states that for large VALUES of x, π(x) is approximately equal to x/ln(x). Ancient Greek mathematicians were the first to STUDY the mathematical properties of prime numbers. (Earlier many people had studied such numbers for their SUPPOSED mystical or spiritual qualities.) While many people noticed that the primes seem to “thin out” as the numbers get larger, Euclid in his Elements (c. 300 BC) may have been the first to prove that there is no largest prime; in other words, there are INFINITELY many primes. Over the ensuing centuries, mathematicians sought, and failed, to find some formula with which they could produce an unending sequence of primes. Failing in this quest for an explicit formula, others began to speculate about formulas that could describe the general distribution of primes. Thus, the prime number theorem first appeared in 1798 as a conjecture by the French mathematician Adrien-Marie Legendre. On the basis of his study of a table of primes up to 1,000,000, Legendre stated that if x is not greater than 1,000,000, then x/(ln(x) − 1.08366) is very close to π(x). This result—indeed with any constant, not just 1.08366—is essentially equivalent to the prime number theorem, which states the result for constant 0. It is now known, however, that the constant that gives the best approximation to π(x), for relatively small x, is 1. The great German mathematician Carl Friedrich Gauss also conjectured an equivalent of the prime number theorem in his notebook, perhaps prior to 1800. However, the theorem was not proved until 1896, when the French mathematicians Jacques-Salomon Hadamard and Charles de la Valée Poussin independently showed that in the limit (as x increases to infinity) the ratio x/ln(x) equals π(x). |
