Given s=(1,2,3,4,5,6,7,8,9,10)and a relation r on a where r=(x,y)x+y=10........find whether r has the following properties or not?I |
|
Answer» Answer: In roster FORM, R= {(1,9),(2,8),(3,7),(4,6),(5,5),(6,4),(7,3),(8,2),(9,1)} Clearly, no (1,1), (2,2).... EXCEPT (5,5). Hence, ¥a€R, (a,a)not€R. So, R is not reflexive. Now, ¥ (a,b)€R, (b,a)€R. So, R is symmetric. However, no c exists such that ¥(a,b)€R and (b,c)€R, there could be (a,c)€R. So, R is not transitive. |

What we use point in daly life |
|
Answer» Answer:Everyday life, daily life or routine life comprises the ways in which people typically act, think, and feel on a daily basis. Everyday life may be described as mundane, routine, natural, habitual, or normal.Human diurnality MEANS most people sleep at least part of the night and are active in daytime. Most eat two or three meals in a day. Working time (apart from shift work) MOSTLY involves a daily schedule, beginning in the morning. This PRODUCES the daily RUSH hours experienced by many millions, and the drive time focused on by radio broadcasters. Evening is often leisure time. BATHING every day is a custom for many. |

If alpha and beta are zeroes of p(x)=x2+x-2, find the value of 1/alpha - 1/beta. |
|
Answer» Answer: 3 / 2 or - 3 / 2 Step-by-step EXPLANATION: Polynomials written in the form of x^2 - Sx + P REPRESENT S as sum of their roots and P as product of their roots. Here, polynomial is x^2 - ( - 1 )x - 2. So S = - 1 and P = - 2. P = αβ = - 2 S = sum of roots = - 1 ⇒ α + β = - 1 Square on both sides: ⇒ ( α + β )^2 = ( - 1 )^2 ⇒ α^2 + β^2 + 2αβ = 1 ⇒ α^2 + β^2 + 2( - 2 ) = 1 ⇒ α^2 + β^2 = 1 + 4 ⇒ α^2 + β^2 = 5 ⇒ α^2 + β^2 - 2αβ = 5 - 2αβ ⇒ ( β - α )^2 = 5 - 2( - 2 ) ⇒ ( β - α )^2 = 9 ⇒ β - α = 3 or - 3 In QUESTION, 1 / α - 1 / β ⇒ ( β - α ) / αβ β - α = 3 or - 3 ; αβ = - 2 ⇒ ( 3 / - 2 ) or ( - 3 / - 2 ) ⇒ - 3 / 2 or 3 / 2 |

two pipes a and b can fill a tank in 20 minutes and 30 minutes respectively . If initially only pipe b was kept open for 2/5th of the total time and both pipes a and b were kept open for the rest of the time then how many minutes would both pipes take to fill the tank |
|
Answer» Step-by-step explanation: Pipe A 1 hr work=1/30 Pipe B 1 hr work=1/20 let total time required to FILL the tank =xhrs since pipe B is open for half hr so work done by pipe B in X/2 hrs =x/40hrs and work done by pipe (A+B) in remaining x/2 hrs=x/24hrs so total work done is =x/40+x/24 1=x/40+x/24 =>1=8x/120 =>120=8x so x=15hrslet x will be COMPLETION time so, x/2*(1/20) + x/2*(1/30 + 1/20)=1 8x=120 x=120/8 x=15 ans I hope it will help you to UNDERSTAND ❤ |

Answer» The Elimination Method This method for solving a pair of simultaneous linear equations REDUCES ONE equation to one that has only a single variable. Once this has been done, the solution is the same as that for when one line was vertical or parallel. This method is known as the Gaussian elimination method.
Example 2. Solve the following pair of simultaneous linear equations: Equation 1: 2x + 3y = 8 Equation 2: 3x + 2y = 7 Step 1: Multiply each equation by a SUITABLE number so that the two equations have the same leading coefficient. An easy choice is to multiply Equation 1 by 3, the coefficient of x in Equation 2, and multiply Equation 2 by 2, the x coefficient in Equation 1: 3 * (Eqn 1) ---> 3* (2x + 3y = 8)---> 6x + 9y = 24 2 * (Eqn 2) ---> 2 * (3x + 2y = 7)---> 6x + 4y = 14 Both equations now have the same leading coefficient = 6
Step 2: Subtract the second equation from the first. -(6x + 9y = 24 -(6x + 4y = 14) 5y = 10 Step 3: Solve this new equation for y. y = 10/5 = 2 Step 4: Substitute y = 2 into either Equation 1 or Equation 2 above and solve for x. We'll use Equation 1. 2x + 3(2) = 8 2x + 6 = 8Subtract 6 from both sides 2x = 2Divide both sides by 2 x = 1 Solution: x = 1, y = 2 or (1,2).... Please mark brainliest and be my follower for sure |

THE PATH FOLLOWED BY A CIRCULAR OBJECT IS A LINE IS CALLED |
|
Answer» Answer: There ACT TWO forces when an object moves in a CIRCULAR MOTION. The force which keeps an object in a circular path with constant speed acts towards the centre. This force is called CENTRIPETAL FORCE. This force pulls the object inwards. Whereas the force which tends to free the object from centripetal force is called CENTRIFUGAL FORCE. This force tries to ESCAPE out to continue the straight line motion of the object. Both these forces balance each other and hence the body moves in a circular motion. Hence, if the centripetal force is absent, the smaller object will tend to move in straight line motion which will be the tangent to the circular path in which it was revolving. For example - Earth attracts the moon towards it through centripetal force and the moon tries to escape this force using its own centrifugal force. Hence, moon revolves around earth. If earth's centripetal force was absent, the moon would pursue a straight line motion from the point the centripetal force became absent. That's your answer. |

Write divisibility rule of 2,3,5,7,9,11 with one example of each |
|
Answer» Step-by-step explanation: The divisibility rule of 2 is that the last digit is EVEN number then that given would be divisible by 2. The divisibility rule of 3 is that the sum of all digit of that given number would be divisible by 3. The divisibility rule of 5 is that the last digit of that given number is 0 or 5 then that number would be divisible by 5. The divisibility rule of 7 is that the last digit of the given number is DOUBLED and thereafter subtract that result from the rest of the number,if that resulting number is divisible by 7. The divisibility rule of 9 is same as the method of 3. The divisibility rule of 11 is that we have to take the ALTERNATING sum of the digits in the number,read from left to right.If that is divisible by 11,sothat is the number which would be divisible by 11. |

Answer» Solution:- Let x-2=h in this case clearly we can ANALYSE that, x=2+h now putting the value of x we get =>{(4-(2+h)^2) (cosπ(2+h)/4)}/(sin(2+h-2) =>{(4-4-h^2-4h)^1/2 ×(cosπ(2+h)/4)}/(sin(h)) =>{-h(h-4)^1/2 ×cosπ(2+h)/4}/(sin(h)) dividing denominator and numerator by h we get =>{(4-h)^1/2 ×cosπ(2+h)/4}/sin(h)/h we know (SINX)/x=1 so,sin(h)/(h)=1 =>{(4-h)^1/2 ×cosπ(2+h)/4}/1 as h is trending to 0 so, NEGLECTING h we get =>2×cosπ/2 =>2×0=0
