Two alarm clocksring their alarms at regular intervals of 50 seconds and 48 seconds. If they firsteep together at 12 noon, at what time will they beep again for the first time? |
|
Answer» They will beep together after time intervalwhich is multiple of both i.e. 50 and 48. That means we have to find out the LCM of 50 and 48. 48=2x2x2x2x350=2x5x5LCM of 48 and 50 is = 2x2x2x2x3x5x5= 1200 so the bell will rang together after 1200 s or 1200/60 minutes = 20 minutes time = 12:20 pm |

x**6 %2B 5*x**3 %2B 8 |
|
Answer» x^6 + 5x^3 + 8 = (x)^6+ 5x^3 + 8 + x^3 - x^3 = x^6 + 6x^3 + 8 - x^3 [By adding and subtracting x^3 on both sides] = (x^2)^3+ (2)^3+ (-x)^3 - 3 × (x^2) × (2) × (-x) According to the identity, x^3 + y^3 + z^3 - 3xyz = (x + y + z) (x^2 + y^2 + z^2 – xy – yz – zx) = (x^2 + 2 - x)[(x^2)^2 + (2)^2 + (-x)^2 - (x^2) × (2) - (2) × (-x) - (x^2) × (-x)) = (x^2 - x + 2)(x^4 + x^2 + 4 - 2x^2 + 2x + x^3) = (x2 - x + 2)(x4 + x3 - x2 + 2x + 4) Thus, the facotrs of x6 + 5x3 + 8 are (x2 - x + 2)(x4 + x3 - x2 + 2x + 4). |
