Olarewajub:Let y=Log(2x-1) to base 10 Therefore, 10^y = 2x-1 Take the natural log of both sides Ln 10^y = Ln (2x-1) Y Ln10 = Ln (2x-1) Take the derivative of both sides wrt x (dy/dx) Ln10 + 0 = (1/2x-1)x 2 Therefore, dy/dx =( 2/2x-1)(1/Ln10)

pls someboddt shud help me with this question find the Laurent expansion of the indicated singularities. hence name the singularities and state the radius of convergence 1. ( Z - Sin Z )/ Z^3 ; Z = 0 2. ( Z - 3) sin(1/( Z + 2)) ; Z =-2 3. Z/(Z +1)(Z +2) ; Z = -2 4. 1/Z^2 ( Z - 3)^2 ; Z = 3 |

Pls someone should help me with this... Solve: dy/dx+1/2y=3/2 with y(d)=4...thanks |

please friends help solve this 4 workers get paid N160000 for working for five days. How much will 5 workers get paid for a day? Select one: a. N 40,000 b. N 30,000 c. N 25,000 d. N 10,000 |
Re: Nairaland Mathematics Clinic by Nobody: 12:46pm On Jul 16, 2017 |
Kentnickole: If 4 workers work for 5 days, 1 worker will work for 20 days. Hence, 1 worker will earn 160000 in 20 days. Meaning that the worker will earn 8000 in a single day. While 5 workers in a single day will then earn 40000. Thanks. |

Kentnickole:4 workers get paid 160,000 for 5 days 1 worker will get paid 40,000 for 5 days 1 worker will get paid 8000 for 1 day 5 workers will get paid 8000*5 for 1 day Therefore, 5 workers will get paid 40,000 for 1 day 1 Like |

good morning house..pls am in a bit of emergency..we were given an econometrics assingment question to be submitted tomorrow morning..30marks.. Pls i would be grateful if given assistance.. Let me try and type the question as given Yi = -66.1058+0.0650Xi Se= (10.7509) ( ) t = ( ) (18.73 ) R^2 =0.9460 n = 20 questions.. 1, fill in the missing information 2, will you reject the hypothesis that B2(that is B subscript 2) =0 at 50% significance level? 3, tell wether one tail test or two tail test is more appropriate |
Re: Nairaland Mathematics Clinic by kingnas(m): 9:51am On Jul 17, 2017 |
this is also part of the Econometrics assingment question... Thou the 2 questions are not entirely dependent.. Question Given a typical regression model with two independent variables x1 and x2 1, find the ols estimators B1, B2 and B3 2,fine the coefficient of determination relevant to the model. Pls note that x1 means x subscript 1.. And so on... And B1 means B subscript 1 nd so on |
