Business › CBN Probes Naira Depreciation In Parallel Market by Obinoscopy(op): 7:39pm On Jul 17, 2015
Naira has depreciated by N42 in the parallel market since June 28, when the apex bank banned 41 items from the foreign exchange market.

From N220 per dollar as at June 28, the parallel market exchange rate rose to N242 as at yesterdayMiffed by the pace of this depreciation, Vanguard investigations revealed that the CBN dispatched three of its directors to Lagos, Tuesday, to conduct market surveillance.

Specifically, they were given the mandate to discuss with Bureau de Change (BDC) operators to ascertain what is causing depreciation of the Naira in the parallel market, and measures that can be deployed to address the depreciation.

Confirming this development to Vanguard, Managing Director, Sabil BDC, Alhaji Aminu Gwadabe, said the CBN team wanted to know why the Naira is depreciating even  on Wednesdays when the CBN sells to BDCs.

“We told them that the reason is that the forex users know that CBN sells to BDCs on Wednesdays, hence they always position their demand against what the BDCs will get from CBN. But because what the CBN sells to us is not enough to meet the demand, the exchange rate rises further.

“We also told them that the solution is to increase the amount of forex they sell to BDCs. That is how we can narrow the N46 gap between the official rate and the parallel market exchange rate.

”This was corroborated by Managing Director, H. J. Trust BDC, Mr. Harrison Owoh, saying: “The depreciation of the Naira in the parallel market is driven by genuine demand from importers banned from the foreign exchange market. You know we cannot sell to them. They can only buy from the black market. Hence the black market is dictating the rate.

“More so, BDCs have only two sources of dollars — what we buy from CBN and from walk-in-customers. So, we don’t have supply, we also are limited in who we can sell to. So the market is determined by the black market. The solution is for the CBN to increase dollar sales to BDCs, otherwise the rate might continue to go up.”

Ok, that rules out testicular cancer. However you urgently need to see a doctor.

Dollyak:
Factoring the coeeficient of friction mean the net force on the skier on the ski jump parallel to the ski jump surface is a combination of the gravitation force and the frictional force,
For simplicity
F(net)= mg (sinθ -μcosθ)

The net work done on the skier as he travels down the jump is W= FL where L is the length of the jump, L=50/sinθ


By the work-energy theorem the skier launches horizontally from the bottom of the jump with a speed
v(=(2gh(1-μcotθ))^2
After the skier launches (and treating the launch point as x,y=0), the horizontal and vertical position of the skier are
and at the moment of impact, (x,y)=(0,0)
x=vt, y=-1/2 (gt)
The landing spot is on the line , so we have a system of equations we can solve for t=3.794 seconds.
v=29.919m/s check attached pictures to see how I solved for v


More detailed calculation using conservation energy. ..

Using the conservation of energy principle, the work done by friction must be equal to the change in the mechanical energy of the system (h = 50m, alpha = 30°),
(1/2mv^2)-mgh=-μmgcosθ(h/sin30)
This implies
v=sqrt (2gh (1-μcot30))
During the fall, using parallel (x axis pointing 'downwards') and perpendicular (y axis pointing 'upwards') axes in respect to the hill, we can write down the variation of y with time as
y=y[size=4pt]0[/size]+vsin30t-(g cos at^2)/2)
Setting y=0 and solving for t(h'=5m)
t=vtana/g (1+sqrt (1+(2gh'/v^2 tana^2)))=3.795
This is more like it. You can see that your previous calculation was wrong:

Dollyak:
Number 4 is quite easy too as well.
If you think about this. The total amount spent in the air by the skier is the same as the time taken to slope down(starting from the horizontal position) the whole distance of 50meters.
thus distance gives =1/2 at t^2
Therefore 50=1/2 × gt^2 = 1/2 (9.8 )t^2 =50 solve for t
T= 3.2 seconds

Very easy because time only depends on gravity in this case.
Nevertheless I must say I'm impressed. I doff my hat for you.

You didn't make use of the coefficient of friction (0.05)?

To solve 4:

I can use the conservation of energy formula: KE + Frictional Energy = PE
Therefore 0.5mv2 = 0.95mgh. From there we can calculate v.

To get t: We can use the formula s = ut + 0.5gt2
Where u = v and g = -9.8
This gives us a parabola.
The parabola made intersections with the straight line (which made an angle 30 with the horizontal)
Equating the parabola with the straight line should give us the value of t

mickyeddi:
Nice try dude but this another take:

suppose, p_n(x)=x^6+n=x^6±y^a.
the expressions "x^6+y^a" & "x^6-y^a" can be factorized only for the following values of "a"
x^6+y^6=(x^2+y^2)(x^4-x^2y^2+y^4)
x^6-y^6=(x+y)(x-y)(x^2+xy+y^2)(x^2-x*y+y^2)
x^6-y^4=(x^3+y^2)*(x^3-y^2)
x^6+y^3=(x^2+y)(x^4-x^2y+y^2)
x^6-y^3=(x^2-y)(x^4+x^2y+y^2)
x^6-y^2=(x^3+y)*(x^3-y)
because | n | < 500 and "y" (±y^a=n) must be an integer, for different values of "a" y^6=0,1,64 y^4=0,1,16,81,256 y^3=0,1,8,27,64,125,216,343 y^2=0,1,4,9,16,25,36,49,64,81,100,121,144,169,196,225,256,289,324, 361,400,441,484
possible values of "n" =y^6=0,1,64 =-y^6=0,-1,-64 =y^4=0,1,16,81,256 =y^3=0,1,8,27,64,125,216,343 =-y^3=0,-1,-8,-27,-64,-125,-216,-343 =-y^2=0,-1,-4,-9,-16,-25,-36,-49,-64,-81,-100,-121,-144,-169,-196,-225,-256,-289,-324,-361,-400,-441,-484
We can get all possible values of "n" by making an union of these 6 set of numbers (I am using the word "union" because some values have occurred more than one time). That gives 35 distinct values of "n".
I agree with the logic in your calculation.

Nobody has even attempted the questions. Na wa. I'm busy but let me give the mathematicians in the house my suggested hint on how to solve qxn 1:

https://static2.businessinsider.com/image/51801203eab8ea554100000c-1200/tadewos-abiye-getachew-17-nailed-this-tricky-algebra-question.jpg

x3 + a3 can be factorised into (x + a)(x2 - ax + a2)
Therefore we can express x6 + a6 as (x2 + a2)(x4 - a2x2 + a4)
Thus if we can find the various numbers of n that can be expressed in the form a6 (note that both n and a should be integers)
This means we need to find the various values of a such that a6 is less than 500.

Now that means the values of n are 0 (06), 1 (16) and 64 (26). 3 is not included because 36 is 729 which is greater than 500.

Politics › We Have No Hand In Ekweremadu’s Invitation By Police – APC by Obinoscopy(op): 9:44pm On Jul 05, 2015
In a statement issued in Abuja on Sunday by its National Publicity Secretary, Alhaji Lai Mohammed, the party said it neither wrote a petition to the police nor is it aware that any petition was written against the Deputy Senate President.

“However, if, as the PDP claims, the petition concerns alleged altering of the Senate’s Standing Rules on the process of electing Presiding Officers, that is a clear case of forgery which the police have a duty to investigate. Questioning the right of the police to carry out their duties in this regard amounts to intimidating the security agency.

“Forgery is a crime that is being regularly investigated by the police, and it beggars belief that such investigation will now be interpreted to mean that Nigeria is descending into dictatorship or that democracy and the enjoyment of personal freedoms are now endangered. These claims by the scaremongering PDP are far fetched and preposterous,” it said.

APC said if indeed there is a petition against Senator Ekweremadu, he should gladly heed the invitation by the police so he can clear his name, adding that no one is above the law.

“President Muhammadu Buhari has repeatedly said that at every point, the law must be supreme and everyone must respect the law, if the nation’s democratic system is to survive. Extrapolating a police invitation of anyone, no matter his status, to mean the onset of dictatorship is itself an invitation to lawlessness and anarchy, which permeated the long but ineffective rule of the PDP,” the party added.
