Answer» Step-by-step explanation: 1. (9/11) -( - 1 /5) = 9*5-(-1*11)/11 = 45+11/55. (as - *- = +) = 56/55 Therefore, 56/55 should be subtracted from 9/11 to get (-1/5). ** you can check the answer by subtracting 56/55 from 9/11 : 9/11 - 56/55 = 9*55 - 56*11/605 = 495 - 616 /605 = - 121/605 = - 0.2 = - 1/5 2. = sum of 3/7 and 2/9 = 3*9 + 2*7/63 = 27+14/63 = 41/63 = product of 3/10 and 7/8 = 3*7/10*8 = 21/80 Now divide 41/63 and 21/80 = 41/63 ÷ 21/80 = 41*80/63*21 = 3280/1323 ( answer) |

10.If the area of the circle x2+y2-4x-2y+k=0 is 250 sq. cms,then k=1)-202) 203) + 20 430 |
Answer» ANSWER :k = -74.6 Solution :★ Note : The standard form of a circle is given as : (x - H)² + (y - k)² = r² where (h,k) is the centre and r is the radius of the circle . Here , The given equation of circle is ; x² + y² - 4x - 2y + k = 0 The given equation of circle can be rewritten as ; => x² - 4x + y² - 2y = -k => (x² - 4x + 2²) + (y² - 2y + 1²) = 2² + 1² - k => (x - 2)² + (y - 1)² = 4 + 1 - k => (x - 2)² + (y - 1)² = 5 - k Now , Comparing the above equation with the standard form (x - h)² + (y - k)² = r² , we have r² = 5 - k . ALSO , The AREA of given circle is 250 cm² . => A = 250 => π•r² = 250 => π•(5 - k) = 250 => 3.14•(5 - k) = 250 => 5 - k = 250/3.14 => 5 - k = 79.6 => k = 5 - 79.6 => k = -74.6 Hence k = -74.6 |
