Starpress:Well, I wasn't following his story. I thought the wife was angry at the DNA testing being made public. If that be the case, then I would say Gyan is a hypocrite and has no regard and respect for his wife. Personally, if I were the wife, I would divorce and dump his ass. |
Darivie04:When you place various masses on a plane, there is a point on the plane at which the plane(together with the masses) would balance on a pencil tip. What is that centre of balance for the mass system I gave in question four? |
ubunja:I understood you right from time, I am just explaining to him. He is new to this thread. ![]() |
Things like this make me wanna say nyash is a fundamental human right.

MARCH - JANUARY ME : hello bae? GIRL : *no response* FEBRUARY 13th GIRL : Hi luv ME :

Amakavula:I made that comment the day you posted your answer. You booked space, remember? |

Hermes019:He doesn't have any evidence or sound basis to believe in god instead he believes by FAITH. Any attempt to make him bring evidence will fail. |
NB : Show your working 1) Give me the formula for the volume V of a solid formed by taking a sphere of radius R and boring a cylindrical hole of radius r through it with the centre of the sphere lying on the axis of symmetry of the cylinder. ![]() 2) Find the mass of the solid sphere of radius 5 metres whose variable density at every point on the sphere is such that it is linearly proportion to the distance from the centre of the sphere. 3) Give me the coordinates of the centre of the region in the plane bounded by the graphs of f(x) = 4 - x² and g(x) = x + 2 ? 4) I placed the following six masses : 7kg, 6kg, 5kg, 4kg, 3kg and 2kg on the cartesian plane and they have the following coordinates (2, 3), ( ½, 4), (-3, 2), (-4, 1), (3, - 2) & (1, 1) respectively. What are the coordinates of the point on which I can balance the cartesian plane on the tip on a pencil without it tipping over? |
COOL10:The direction of a vector in the plane is given by the angle θ it makes with the positive direction of the x-axis. The direction of the vector V = X i + Y j is given by finding θ in the equation tan θ = Y ÷ X . Try this with both vectors and you won't get the same θ . Another technique is to observe that if two vectors, say V and T , are pointing in the same direction, then there exist a positive scalar k Such that V = k T . Consequentially , T = (1/k) V . ![]() |
Kelly2713:1) The total area of the metal sheet is equal to the total area of the box. Given that the box has square ends and rectangular sides the the surface area SA of the closed box is SA = 4yx + 2x² = 216 , this reduces to 2yx + x² = 108 . 2) The volume V of the box is given by V = V(x,y) = x²y . Solving for y in the surface area gives y = (108 - x²) ÷ 2x . Substituting this into the volume equation yields V = V(x) = 54x - (½)x³ . This is the equation to be maximised and by logic, the domain of x is the open interval 0 < x < (216)^½. 3) To find the value of x that yields the maximum volume, you need to find the critical number(s) of the volume function. The critical number for this equation will only occur at x - values for which dV/dx = V'(x) = 0 . Given that dV/dx = V'(x) = 54 - 2(¾)x² , the x - values for which dV/dx = V'(x) = 0 are ±6 , we pick 6 because it lies in the feasible domain of x . So the value of x that maximises V = V(x) is 6cm. 4) to find the corresponding value of y that maximises V = V(x) = V(x,y) , put the value of x that maximises V= V(x) into the surface area equation and solve for y . Doing this yields y = 6cm . 5) So if the square ends of both boxes are 6cm × 6cm and the four rectangular sides are of the dimensions 6cm × 6cm , you will get the maximum volume. ![]() |
ubunja:Anyone that believes in god and is still asking if he said god was alive really puts a lot of mud in the water. As a religious man, you need not say god is alive because all religious gods are supposedly alive. Anyways on this topic of god, I don commot hand for your matter.

ubunja:Okay then. I assumed you were a christian because of this post of yours.
|
If I were Gyan, I would have done the DNA test in secret as I see no reason for treating the issue in public. Besides, the fact that the children turned out to be his doesn't mean madam didn't cheat. Madam should try and forgive that childish man. |
ubunja:Okay then, I just have two question. 1)Are you a christian? 2)What's your idea about god? |
ubunja:You didn't need to say so, the bible makes it clear that god is alive. Don't you believe that god is alive? |
ubunja:Iol. I no know wetin do UyaiIncomparabl. As I have said, I don commot hand for her matter. ![]()

Lol. You are wrong. It's impossible for that exact force to "directly" cause such an acceleration. Remember that mass is a scalar and force(vector) is a scalar multiple of acceleration(vector) ie. F = m a . This show that the acceleration must be in the same direction as the force that's causing it. So given that such force isn't in the same direction with the object, the question to ask is "what vector component of the force F = 10 i + 5 j is acting in the direction of the acceleration a = 4 i + j ?" that vector component is the force F' = (1/17)[180 i + 45 j ]. So you will get your mass by looking for the scalar m that satisfies F' = m a by using component equality. So (180/17) = m(4) or (45/17) = m(1) The mass is (45÷17)kg = 2.65kg (3 s.f) ![]() |
Ubunja and akin1212, there is no need to quarrel. Let the discussion not stray from maturity. |
CAPSLOCKED: ![]() |
Amakavula:Nobody believed the Black Swan because there were no evidences to support it's existence, that's rational of them. They then changed their minds when they saw sound evidence for the Black Swan, that's completely rational of them. I would expect the same from people when it comes to the existence of god. Martinez39 doesn't believe in the existence of god because there are no evidences to support such, that's rational. Martinez39 will only believe in god if you provide sound evidences for his existence. If I go by your logic, I would say that there are two dragon eggs on CAPSLOCKED's head and you should believe it because, just like the Black Swan, it exists even though people haven't seen sound evidences for their existence yet. ![]() |
Gluckudom1:Your inability to understand my simple topic despite the clarifications is not my fault.
