|
Answer» A collection of rational numbers and irrational numbers make up the set of real number. A real number can be expressed on the number line and has some specific properties. They satisfy:\tThe commutative law of addition. That is, when a and b are two real numbers then a + b = b + a. For example 1 + 3 = 3 + 1 = 4\tThe commutative law of multiplication. That is, when a and b are two real numbers then a x b = b x a. For example 1 x 3 = 3 x 1 = 3\tThe associative law of addition. That is, when a, b and c are three real numbers then a + (b + c) = (a + b) + c. For example 1 + (3 + 4) = (1 + 3) + 4 = 8\tThe associative law of multiplication. That is, when a, b and c are three real numbers then a x (b x c) = (a x b) x c. For example, 1 x (3 x 4) = (1 x 3) x 4 = 12 The number which is represent in number line |

(1,2) (4,y)(x,6)(3,5) are vertices of parallelogram find x and y. |
| Answer» Let A → (1, 2), B → (4, y), C→ (x, 6) and D→ (3, 5).We know that the diagonals of parallelogram bisect each other.So, Coordinates of the mid-point of diagonal AC= Coordinates of the mid-point of diagonal BD{tex}\\Rightarrow \\left( {\\frac{{1 + x}}{2},\\frac{{2 + 6}}{2}} \\right) = \\left( {\\frac{{4 + 3}}{2},\\frac{{y + 5}}{2}} \\right){/tex}{tex}\\Rightarrow \\left( {\\frac{{1 + x}}{2},4} \\right) = \\left( {\\frac{7}{2},\\frac{{y + 5}}{2}} \\right){/tex}{tex}\\Rightarrow \\frac{{1 + x}}{2} = \\frac{7}{2}{/tex}{tex}\\Rightarrow{/tex} 1 + x = 7{tex}\\Rightarrow{/tex} x = 6and {tex}4 = \\frac{{y + 5}}{2}{/tex}{tex}\\Rightarrow{/tex} y + 5 = 8{tex}\\Rightarrow{/tex} y = 3 | |

Solve by using formula method a(x^2+1)=x(a^2+1) |
| Answer» = ax2 + a - xa2 - x= ax2 - xa2 - x + a= ax(x - a) - 1(x - a)= (x - a)*(ax - 1)To find roots, we have to equate (x - a) = 0 and (ax - 1) = 0So, x - a = 0 and ax - 1 = 0=> x = a, ax = 1=> x = a, 1/a | |

Prove root5 is irrational no. |
| Answer» let √5 be rationalthen it must in the form of p/q [q is not equal to 0][p and q are co-prime]√5=p/q⇒ √5 × q = psquaring on both sides⇒ 5× q× q = p× p ------> 1p×p is divisible by 5p is divisible by 5p = 5c [c is a positive integer] [squaring on both sides ]p× p = 25× c× c --------- > 2sub p× p in 15× q× q = 25× c× cq× q = 5× c× c⇒ q is divisble by 5thus q and p have a common factor 5there is a contradictionas our assumsion p &q are co prime but it has a common factorso\xa0√5 is an irrational | |
