If 2tan(A-B)=cotB then the value ofcotB+tanB |
|
Answer» tan A is the answer . Step-by-step explanation: we know , tan ( A - B ) = (tan A - tan B) / ( 1 + TANA tanB ) now , using this FORMULA , we have , 2 [ tan A - tan B ] / 1 + tanA tanB = COT B => 2 { tan A - tan B } = cot B ( 1 + tan A tan B ) => 2 tan A - 2tan B = cotB + tan A (tanB × cotB) => 2 tan A - 2 tan B = cot B + tan A (1) => 2 tan A - tan A = cot B + 2 tan B => tan A = cot B + 2 tan B |

The product of two consecutive positive integers is 306 we need to find integers. |
|
Answer» Step-by-step EXPLANATION: Let two consecutive NUMBERS are X and (x + 1) A/C to QUESTION, product of x and (x + 1) = 306 ⇒x(x + 1) = 306 ⇒x² + x - 306 = 0 ⇒ x² + 18x - 17x - 306 = 0 ⇒x(x + 18) - 17(x + 18) = 0 ⇒(x + 18)(x - 17) = 0⇒ x = 17 and -18 Hence, numbers are x = 17 and (x +1) = 18 |

There are 21 girls in a queue including Saisha.The number of children behind Saisha is four times the number of children ahead her.What is Saisha's position in the queue? |
|
Answer» Answer: Saisha's position in the queue is 5th. Step-by-step EXPLANATION: Let, there are a number of STUDENTS ahead Saisha. And due to this, position of Saisha should be ( a + 1 )th. Here, The number of children behind Saisha is FOUR times the number of children ahead her. Total number of girls is 21. = > Number of girls behind Saisha = four times of the number of girls ahead Saisha. = > Number of girls behind Saisha = 4 X a = > Number of girls behind Saisha = 4a Then, = > Total number of girls = 21 = > Number of girls ahead Saisha + 1( that's Saisha ) + number of girls behind Saisha = 21 = > a + 1 + 4a = 21 = > 5a + 1 = 21 = > 5a = 21 - 1 = > 5a = 20 = > a = 20 / 5 = > a = 4 Hence the present position of Saisha is ( a + 1 )th i.e. ( 4 + 1 )th i.e. 5th. |

if AB*BA=BCB ehere a b c stand for one digit then calculate A+B+C=...? where Anot equal to B not equal to C. |
|
Answer» Finding place VALUES: ab*ba = bcb (10a + b)* (10b + a) = 100b + 10c + b 100ab + 10(A2 + b2) + ab = 101b + 10c 101ab + 10(a2 + b2) = 101b + 10c Equating like terms: When, a (b) = a(c), b = c ab = b ; a = 1 assume b not equal 0. a2 + b2 = c (substituting with value of a) BECOMES 12 + b2 = c a +b + c (after substituting with values) become 1 + b + 1 + b2 = 2 + b + b2 b = 1 and b=0 is not possible SINCE b is not equal to a. For other values of b except 2 c is a double digit number which is not possible. So b = 2 ; hence a + b + c = 2 + 2 + 4 =8 I hope I will help you please mark on berilent answer |

Find the roots of the following quada odioequation by applying the quadratic formulas2x2+x=4=0. |
|
Answer» Answer: hello again Step-by-step EXPLANATION: now see carefully the QUADRATIC equation is given by 2x^2+x-4. see the general form of quadratic equation is ax^2+bx+c. so, a=2, b=1, c=-4. THE FORMULA FOR FINDING ROOTS OF A QUADRATIC EQUATION IS:- -b+_ sq.rt (b^2-4ac)/2a. so, it is seeming easy now, the roots are -1+_sq.rt {(-b)2-4×2×(-4)}/2×2 =-1+_sq.rt (1^2+32)/4 =-1+_sq.rt 33/4. now, -1 +_ root 33/4=0 so it will be either -1+root 33 or -1-root 3 hope this helps u be happy keep smiling keep raising questions |
