2 Tet x be a rational number and y be an irrational number. Is x+ynecessarily an irrational number? Give an example in support of youranswer(2010, 14) |
|
Answer» Rational Number are those numbers which can be expressed in the form p/q where q is not equal to 0 and p and q belongs to integers a rational number can be expressed in the form of decimal too. Say x = 2and y = 3 It clearly states that x+y =5 ( Product is not following the definition of Rational numbers )Proving that x+y is an irrational number. Rational means number between two integer say x and y are 2 and 3 respectively. =1/2(2+3)=5/2 or 2.5 ( Rational number of x and y we get which follow the definition of Rational number ) |

3, Draw an obtuse angled Δ ST(iii) (aDraw its medians and show the centroidtiudes ond denote the orthocentre |
|
Answer» First of all let me tell you an angle is said to be obtuse if it is greater than 90 and is called acute if it is lesser than 90. Now we can call a triangle is obtuse angled if it has any one of its three interior angle as an obtuse angle. The steps for construction is very easy first of all you have to draw a horizontal line of arbitrary length. Secondly with the help of protractor you have to draw any obtuse angle, i.e. more than 90 degree at one side of the line. On the other side of the line draw an acute angle. Extending both the lines you can find they meet at some point say C, which is again an acute angle. |

Show that if two chords of a circle bisects each other they must be diameters of the circle. |
|
Answer» Let AB and CD be two chords intersecting at point O. Join AC and BD.NowΔAOC≈ΔBOD⇒AC=BD⇒∧AC =∧ BD-----------(1)Now,ΔAOD≈ΔBOC⇒AD=BC⇒∧AD=∧BC--------(2) (1)+(2)⇔∧AC+∧AD =∧BD+∧BC⇒ ANGLE "CAD"= ANGLE "CBD"Then CD divides the circle into two equal parts thus CD is a diameterSimilarly AB is also the diameter and they both meet at point OThus they bisect each other |

|
Answer» Maximum number of columns which is common to both the groups = HCF (616, 32) HCF (616, 32) 616 = (32 x 19) + 8 32 = (8 x 4) + 0 Remainder in this case is zero. ∴ HCF (616, 32) = 8 Hence, the maximum number of columns = 8. Like my answer if you find it useful! |
