Two number are in the ratio of 7:5. If they differ by 18, what is the number? |
|
Answer» Answer: Step-by-step EXPLANATION: The numbers are 56 and 40. A/B = 7/5 (1) A-B = 18 (2) From (1) we GET 5A = 7B or 5A - 7B = 0 (3) From (2) we get 5A - 5B = 80 (4) Subtract (3) from (4) and get 2B = 80 so B = 40. A = 40 + 16 = 56 |

State and prove remainder theorem |
|
Answer» Answer: Statement of Remainder Theorem: Let f(X) be any polynomial of degree greater than or equal to ONE and let ‘ a‘ be any number. If f(x) is DIVIDED by the linear polynomial (x-a) then the remainder is f(a). Remainder Theorem Proof: Let f(x) be any polynomial with degree greater than or equal to 1. Further suppose that when f(x) is divided by a linear polynomial p(x) = ( x -a), the quotient is q(x) and the remainder is r(x). In other words , f(x) and p(x) are TWO polynomials such that the degree of f(x) \geq degree of p(x) and p(x) \neq 0 then we can find polynomials q(x) and r(x) such that, where r(x) = 0 or degree of r(x) < degree of g(x). By division algorithm f(x) = p(x) . q(x) + r(x) ∴ f(x) = (x-a) . q(x) + r(x) [here p(x) =x–a] SINCE degree of p(x) = (x-a) is 1 and degree of r(x) < degree of (x-a) ∴ Degree of r(x) = 0 This implies that r(x) is a constant, say 'k' So, for every real value of x, r(x) = k. Therefore f(x) = ( x-a) . q(x) + k If x = a, Then f(a) = (a-a) . q(a) + k = 0 + k = k Hence the remainder when f(x) is divided by the linear polynomial (x-a) is f(a). ✨✨Hope it will be helpful.✨✨ |

The diagnols of a rhombas are 8cm and 6cm. Find the length of each side of the rhombas |
|
Answer» Answer: 5 cm Step-by-step explanation: SINCE diagonals of rhombus ABCD divides the rhombus into 4 parts, let's take ∆AOB from rhombus (O is the point of intersection of diagonal AC and BD). Since it is right-angled at angle AOB, using the Pythagoras's theorem, we can say that (AO)^2 + (OB)^2 = (AB)^2 => 4^2 + 3^2 = (AB)^2 {Diagonals of rhombus are perpendicular BISECTOR of each other} =>16 + 9 = (AB)^2 => 25 = (AB)^2 => 5 = AB Therefore SIDE of rhombus is 5cm. |
