If the sum of first 14 terms of an A•P is 1050 and its first term is 10 find the 20 term |
| Answer» A=10...givenS14=1050⇒ n/2[2a+(n-1)d]=1050⇒ 14/2[20+13d]=1050⇒ 7[20+13d]=1050⇒ 20+13d=1050/7⇒ 20+13d=150⇒ 13d=150-20⇒ 13d=130⇒ d=1020th term = a+19d = 10 + 19×10 = 10 + 190 = 200\xa0 | |

Solve X + Y = 11 and 2 x - 4 Y = - 2 and hence find the value of m for which Y = mx- 3 |
|
Answer» X==7Y==4m==1 By solving these equation, we get, x = 7 and y = 4. Now, by putting the value of x and y in y = mx-3, we get, 4 = m×7-3 => m = 7/7 => m = 1 X = 11 - Y( _1)Putting "X" in othe eq..We get,2×(11-Y) - 4 Y =-222- 2Y -4Y =-2-6Y = - 24 Y= 4 Therefore X = 7Putting in 3rd eq..We get,11= m7 - 3m = 2 |

If 18,a,b,-3 are in A.P then a+b = ? |
| Answer» The answer is 15.Solution: 1st term of A.P(A) =184th term A.P = -3Therefore, -3 = A+(n-1)d -3 = 18+(4-1)d -3-18 = 3d -21 = 3d d= -7.So , a= 18 - 7 a = 11. b = 11 - 7 b = 4.Therefore, a + b = 11 + 4 = 15 | |

|
Answer» GIVEN points are P(2,p), A(6,-5) , B(-2,11)P is the mid point of A & Bfor distance AP : x1= 6 ,y1= -5 , x2 = 2, y2= pAP =√(x1 - x2)² + (y1 - y2)²[ By Distance formula]AP =√[(6 -2)]² + (-5 - p)²AP = √(4)² + [(-5)² +p² +2×5p]AP = √ 16+ [25 +p² +10p]AP = √ 16 + 25 +p² +10pAP = √41 +p² +10pFor distance BP: x1 = -2 ,y1= 11, x2= 2, y2 = pBP=√(-2 -2)² + (11 - p)²= √(-4)² + [(11)² +p² -2×11p]= √ 16 + [121 +p² - 22p]= √ 16 +121 +p² - 22pBP = √137 +p² -22pATQ,AP = BP√41 +p² +10p = √137 +p² -22p[On squaring both sides]41 -137 +p² -p² +10p +22p = 0-96 +32p = 032p = 96p = 96/32p = 3Hence, the value of p is 3. Value of p is 3 The value of p is 3. |
