'A' is the area of a right angled triangle and 'b' is the side containing right angle. Prove that the length of Altitude/hypotenuse=2AB/√(b^4+4A^2) |
|
Answer» Answer:Base of the right angled triangle is 'B' units. Area of the right angled triangle is "A' sq units. A = 1/2 × b × H ⇒ h = 2A / b Another SIDE of the right angled triangle containing the right angle = 2A / b Hypotenuse of the right angled triangle ACCORDING to Pythagoras theorem: (Hypotenuse)2 = (b)2 + (2A / b)2 ⇒ (Hypotenuse)2 = b2 + (4A2 / b2) ⇒ Hypotenuse = √[b2 + (4A2 / b2)] ⇒ Hypotenuse = √[(b4 + 4A2) / b2] ⇒ Hypotenuse = 1/b √[(b4 + 4A2)] Area of the right angle considering hypotenuse as the base. A = 1/2 × 1/b √[(b4 + 4A2)] × altitude on hypotenuse ⇒ 2A = 1/b √[(b4 + 4A2)] × altitude on hypotenuse ⇒ 2Ab = √[(b4 + 4A2)] × altitude on hypotenuse ⇒ Altitude on hypotenuse = 2Ab / √[(b4 + 4A2)] Therefore, length of the altitude on hypotenuse of the right angled triangle is 2Ab / √[(b4 + 4A2)].

If all the words that can be formed using all the letters of the word 'MOTHER' are listed in a dictionary, then what wull be the 309th word? |
|
Answer» Answer: There are 6 letters, each different Before MOTHER, words from E , H will come Words from E = 5! (there are 5 letters to arrange) Words from H = 5!( there are 5 letters to arrange) Now words starting by M will come. First ME will have = 4! (as 4 letters will be arranged) Then MH = 4! Now words with MO First words starting with MOE... =3! And words starting with MOH... =3! the words starting with MOR... =3! Now, words starting from MOT will come words starting with MOTE.. = 2! then after words starting from MOTH will come and first word will MOTHER so, total no. of words before MOTHER = 5! + 5! + 2* 4! + 3 * 3! = 120 +120 + 48 + 18 = 306 so, RANK of MOTHER = 307 |

The length and breadth of rectangle are measured as 10 cm and 5 cm respectively with 0.1 cm accuracy.Calculate area of r |
Answer» Answer:Area of RECTANGLE in TERMS of error limit = 50 ± 1.5 cm sq. Explanation:Given:Length of Rectangle with accuracy = 10 ± 0.1 cm BREADTH of Rectangle with accuracy = 5 ± 0.1 cm To Find: Area of Rectangle in terms of error limits. Now, we know that,=> Area of Rectangle = length × breadth => Area of Rectangle = 10 × 5 => Area of Rectangle = 50 cm sq. Now, we will find area of Rectangle by error limit.=> ∆A = A × (∆L/L + ∆B/B) Now, put the values=> ∆A = 50 × (0.1/10 + 0.1/5) => ∆A = 50 × (0.01 + 0.02) => ∆A = 50 × (0.03) => ∆A = 1.5 So, Area of Rectangle in terms of error limit are 50 ± 1.5 cm sq. |
