Find the value of k if the points A(2,3), B(4,k) and C(6,-3) are colliner |
|
Answer» When three points are collinear then the condition isx1 (y 2 - y3) + x2(y3 - y1) + x3(y1 - y2) = 0Where, x1 = 2, x2 = 4, y1 = 3, y2 = k, x3 = 6, y3 = -3Substituting the values,2(k + 3) + 4(-3 - 3) + 6(3 - k) = 02k + 6 + 4(-6) + 18 - 6k = 02k + 6 - 24 + 18 - 6k = 0-4k + 0 = 0k=0Therefore, The value of k is 0.

Prove that the product of two consecutive positive integer is divisible by2 |
| Answer» Let the two consecutive positive integers be x and x + 1Product of two consecutive positive integers = x (x + 1)= x2 + xCase (i): x is even numberLet x = 2k⇒x2 + x = (2k)2 + 2k = 4k2 + 2k= 2k ( 2k + 1) Hence the product is divisible by 2Case (ii): x is odd numberLet x = 2k + 1⇒ x2 + x = (2k + 1)2 + (2k + 1) = 4k2 + 4k + 1 + 2k + 1= 4k2 + 6k + 2\xa0= 2 (2k2 + 3k + 1) Clearly the product is divisible by 2From the both the cases we can conclude that the product of two consecutive positive integers is divisible by 2. | |

√5is irrational |
| Answer» Let √5 be a rational number and a and b it\'s simplest form .√5=a/b on squaring both sides 5=a²/b² _____ 5b²=a²____ It shows that 5 divides a² then 5 divide a .Put the value of a =5c , Then 5b²=(5c)²_____ 5b²= 25c²_____ b²=5c²____ here 5divides b² then 5 divide b This contradict the fact that a and b are the simplest form of √5. As it is having 5as it\'s common factor. This happen because of our default assumption that √5 is a rational number. So , we conflude that √5 is an irrational number. | |
