Oh there's no immediate rush, but hopefully by my early 30s. I spoke to my father's friend who had a masters in mathematics, began her career in Accenture and worked her way up to being a partner. She was earning 7 figures. :P Although I know that's a rare feat it's something that I'd aspire to...

Hi all, I'm a student in Mathematical Science in which I'm specialising in Mathematics and a little Computer Programming. I love Maths and definitely have a flair for it. I'm also extremely ambitious and am massively motivated by money, I love it. :P Ideally I'd be earning over 250k or even more...

Forces F1 =j + 3k, F2 = j + k and F3 = 2i + j act at the point (0; 1;2), (1;0;3) and (1;1;0) respectively. (a) Find the total force and the total moment about the origin. (b) Find an equivalent system of forces consisting of a single force acting at the (1;0;0) together with a couple.Ok so for...

I figured out another way anyway, thanks though ! :)

Hi all, my end of year Physics exam is tomorrow and I need some help on this question and if someone could help I'd appreciate it. Carbon-14 has a half life of 5730 years, and an equilibrium concentration in the Earth’s lower atmosphere of approximately one atom per 8.3 x 1011 atoms of normal...

Obviously >.< *Facepalm* Thank you.

Hi all, I've answered a question but there's no answer for it, and if ye could tell me if I'm doing it right I'd appreciate it thanks :) Permutation: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 --------------------2 3 1 6 5 4 8 10 13 11 12 7 14 9 (i) Write it as a product of transpositions. I...

Hey, thanks for the feedback. Well for conservation of energy I did this: E = (1/2)*m*v(max)^2 - G*M*m/r(min) = (1/2)*m*v(min)^2 - G*M*m/r(max) I then canceled the 'm's .. and I'm not sure if you can really extract any other information from there?? And if you're talking about this...

A satellite undergoes an elliptic orbit about the Earth of mass M, with maximum distance 6R and minimum distance 3R from the Earth's centre. (a) Show that twice the minimum velocity v(min) = the maximum velocity v(max) = (2/3)*sqrt(GM/R) (b) Show eccentricity = 1/3 We are told that we...

Homework Statement A 100g particle hangs freely at rest on the end of a spring of stiffness 10N/m. If the particle is projected upwards with a speed of 2m/s, find the time taken until it first comes to rest and the distance travelled. Homework Equations Well, there's F = -k.x and of course the...

Nevermind, I got a solution off a friend.

Let T : R2 -> R2 and S : R2 -> R2 be linear transformations defined by: T(x; y) = (5x + y ; 2x + 2y) and S(x; y) = (3x + 2y ; x): (i). Find the image of the line 2x + 3y = 5 under T. (ii). Find the natural matrices of the linear transformations T o S and T^-1 Sorry, I haven't done...
