The sum of the first n term of a series is given by: Sn = 5n^2 - 2n A sequence U1, U2, U3,........ is defined by Ur = Sr - Sr - 1 Express Ur in terms of r in its simplest form and show that the sequence is linear (a.p). Find: (1) the sum Sn of the of the first n terms of the sequence whose rth term is 4 x 2^-r (ii) the value of n for which the difference between S and 4 is less than 10^-4 |

Good afternoon math guru. I will appreciate if this can solve now.

Prove that the relation R in the set of non zero integers Io defined by aRb if a^b = b^a for every a,b element of Io is reflexive and symmetry. |
Re: Nairaland Mathematics Clinic by mathefaro(m): 8:17am On Jan 26, 2022 |
Entrepreneurrr:By definition, the relation is symmetric, because aRb implies that a^b = b^a which in turn implies that b^a = a^b that is, bra. Also, R is reflexive because, a^a = a^a, hence aRa. 1 Like |

Please, help with this question: A ship 'A' steaming due north at 10 km/hr sight at noon, a second ship 'B' in a direction due east and 1⅔ km away, steaming north east at 8 km/hr. Calculate to the nearest degree the bearing of A from B at 12:15 pm. |

Abbeycaesar: Check the algebra I did it in a hurry but I think it should be correct

Re: Nairaland Mathematics Clinic by Abbeycaesar(m): 7:56am On Feb 05, 2022 |
Well done Sir. The question's from MAN Mathematics for Senior Secondary Schools, Book 2. I arrived at the same answer but the answer at the back of the textbook is different (N60.5°W). That could be a mistake from the author. lordbeans: |

MrEDUCATION: Let the square root be sqrt(a)-sqrt(b) Continue with squaring it and equating to the original expression a-2sqrt(ab)+b=28-10sqrt(3) collecting like terms, we have a+b=28................(i) a=28-b.........(ii) -2sqt(ab)=-10sqt(3).......(iii) simplify (iii), ab=75..,.(iv) sub (ii) into (iv) you have, 28b-b^2=75 solving the equation, you get b=25 or 3 i.e when b=25, a=3 and vice-versa hence, your final answer is 5-sqt(3) or sqt(3)-5 |

X is 40° Your answer is wrong. Does that look like a right angle to you in your wildest imagination?? A mathematician solved it and solution is attached. All the angles were solved for. An when you sum up individual triangles, they ALL give you 180 degrees. x is 50°
|
Re: Nairaland Mathematics Clinic by Tradegood: 11:30pm On Apr 13, 2022 |
jackpot: That is not a 90° Someone helped out. All the angles were solved for and when you sum all the angles of all the triangles in the diagram, they all give 180° by the solution below
