**geometry**

V = (pi*r^2*h) / 3 = 54pi. Vn = (pi*(r/3)^2*(h/3)) / 3 = 54pi, Vn = (pi*(r^2/9)*(h/3)) / 3 = 54pi, Vn = (pi*r^2*(1/27)*h) / 3 = 54pi, We have divided the left side of our Eq by 27. Therefore , we must divide the rt. side by 27 also: Vn = (pi*r^2*(1/27)*h) / 3 = 2pi. = New ...

**Physics**

V = 19.8m/s, East. V = at=4.08m/s^2*1.94s = 7.92m/s,West. Vn = 19.8 - 7.92 = 11.88m/s, East. Vn = Net velocity.

**maths**

Vn = Vt-Vb = 46-10 = 36km/h. Vn = 36km/h = 36000m/3600s. = 10 m/s = Net velocity of train. d = V*T = 10m/s * 22s = 220 m. = Length of train.

I disagree with your premise, if that were true, nails would not get hot when struck. Momentum conservation: 550*3.8=550Vh' + 10Vn' Vh'=3.8-1/55 3.8Vn' energy conservation 1/2 550*3.8^2=1/2 550 Vh'^2 + 1/2 10 Vn^2 put the Vh' expression found into this equation, do the math, ...

**math**

There is one step in a proof that I don't understand. Could someone please explain? u = any vector in vector space S W = finite dimensional subspace of S with orthonormal basis of vectors {v1, v2, ..., vn} The theorem to prove is: u can be expressed exactly one way as u = w1...

I'm having trouble visualizing your cash flow picture. Further, I dont have whatever lookup tables you are using. Sorry. That said, the formula for converting something to a present value is PV=Vn/(1+r)^n -- where n is the number of years in the future, and r is the interest (...
