If ( + ) is a factor of+ + + , then find the values of a and b given that – = |
|
Answer» Answer: Step-by-step EXPLANATION: Given is the value of a and b. given that (x+1) is a factor of p(x) therefore, -1 is a zero of given p(x) p(x) = 2x3 +ax2 +2bx +1 substituting the value of -1 in the given p(x),we get p(x)=2*(-1)3 +a *(-1)2 +2*b*(-1)+ 1 = -2 + a -2b + 1 = -1 + a - 2b or,a - 2b = 1 so we got two equations; a - 2b = 7 ...(1) 2a - 3b = 4 ...(2) (1)* (2)* (4)- 2 = 2a - 4b = (3) (2)* 1 = 2a - 3b = 4 (4) (4) - (3) = [2a - 2a ] + [-3b - (-4b)] = 4 - 2 -3b + 4b = 2 therefore b = 2 substituting the value of b in (3) 2a - 4b = 2 2a - (4*2) = 2 2a - 8 = 2 2a = 2 + 8 2 = 10 a = 10 / 2 therefore a = 5 so we get the value of a and b that is ; a = 5 and b = 2 |

SinA(1+tanA)+cosA(1+cotA)=secA+cosecA |
|
Answer» Step-by-step EXPLANATION: ANSWER sinA(1+tanA)+cosA(1+cotA) =sinA+sinAtanA+cosA+cosAcotA =sinA+sinA cosA sinA
+cosA+cosA sinA cosA
[∵tanA= cosA sinA
,cotA= sinA cosA
] =sinA+ cosA sin 2 A
+cosA+ sinA cos 2 A
= sinAcosA sin 2 Acos+sin 3 A+cos 2 AsinA+cos 3 A
= sinAcosA sinAcosA(sinA+cosA)sin 3 A+cos 3 A
= sinAcosA sinAcosA(sinA+cosA)(sin 2 A+cos 2 A−cosAsinA)
[∵a 3 +b 3−(a+b)(a 2 −ab+b 2 ) ] = sinacosA (sinA+cosA)sinAcosA+sin 2 A+cos 2 A−sina+cosA
= sinacosA (sinA+cosA).1
[∵sin 2 a+cos 2 A=1 ] = sinAcosA sinA
+ sinAcosA cosA
= CosA 1

Study of profit on sale of shares |
|
Answer» Answer: Profits arising from the sale of equity shares can be taxed as capital gains or business INCOME, depending on various FACTORS (eg, the taxpayer's intention to invest in the shares, the frequency and volume of purchase and sales transactions UNDERTAKEN by the taxpayer and the treatment of shares in the taxpayer's books of accounts). While the classification of gains arising from a sale of shares has previously been litigated, the Bombay High COURT recently dealt with the issue of whether gains arising from such sale by a private trust would be taxable as capital gains or business income. After considering various aspects, the court HELD that such income is taxable as capital gains and not as business income. |

Answer» Answer: Asalamu waliakum RELIGIONS are attempts to reach out to God. Each of them depicts reality differently. It might be possible that all of them are wrong or false, but all of them cannot be true. If you believe that one of them is true, then every other religion is false. So you cannot believe in two or more religions at the same time without getting into problems with reason and logic. Each religion presents itself as the best explanation of the one true reality. For example, when people die, they either: 1. REINCARNATE, or 2. Go to heaven or hell, or 3. Nothing happens, or 4. Something else happens. Each of these options is an exclusive claim. If people reincarnate, then going to heaven or hell or nothing happens are totally wrong. In other words, they cannot be all true. They may all be wrong, but they cannot be all correct. We only have one true reality, and whatever happens to any John DOE will also occur to any Jane Doe. Either both will reincarnate or both will go either to heaven or hell, or nothing will happen to both of them. It is not realistic to believe that if you are a Hindu, you will reincarnate, and if you are a Christian, you will go to heaven, or if you do not believe in God, nothing happens to you. Then we do not have one single reality in this case. But we know there is only one reality! Another example - are there many Gods or is there only one God? Both propositions cannot be true at the same time. If say Hinduism is true, then Judaism, Islam and Christianity are all false. It is the same the other way around. Is Jesus God? Either He is, or He is not; He cannot be God and not God at the same time. Is Jesus the only way to the FATHER or not? Either He is, or He is not. Is Mohammed the true prophet? He is, or He is not. It is one or the other. Both propositions cannot be correct at the same time. Every person should then look for the religion that represents what reality is and seeks God there because there are only true and false religions out there.

a and b together can do a piece of work in 20 days b and c together can do it in 15 days , c and a can do it in 12 days |
|
Answer» Step-by-step explanation: a+B 1 day work = 1/12 -------> EQUATION 1 b+c 1 day work= 1/15 ----------> equation 2 c+a 1 day work= 1/20 -------------> equation 3 by subtracting equation 1 and 2 we get a-c = 1/60 --------------------> equation 4 now adding equation 3 and 4 we get A's one day work a=1/30 ------------------------> equation 5 now PUTTING value of equation 5 in equation 1 and 3 we can get value of C and B RESPECTIVELY 1/20 and 1/60 A's one day work + B's one day work + c's one day work = 1/10 if they work together it will TAKE 10 days to complete them the whole work ! |
