If both sides are equal, then

**k**= 0,5 Good luck!2 Answers · Science & Mathematics · 29/01/2012

See binomial equation [1 + x]^n =

**C**(n,0)+ x***C**(n,1) +(x^2)***C**(n,2)+ (x^3)***C**(n,3) ... + [x^n-1]***C**(n,n-1) + (x^n)**C**(n,n) Now differentiate this equation on both sides w.r.t. x n*(1+x)^n-1 = 1***C**(n,1)+ (2*x)***C**(n,2) + (3x^2)***C**(n,3)+ ... + (n-1)*[x^n-2...3 Answers · Science & Mathematics · 28/10/2015

If d divides both

**k**and one of a,b,**c**, then d divides**k**- abc = 1. If d is a positive integer, this implies d = 1. Now apply that to the gcd's.2 Answers · Science & Mathematics · 25/01/2012

(1) By the slope formula, the slope of the line that passes through A and B is just: m = Δy/Δx = (k - 4)/(1 - 3) = (k - 4)/(-2) = (4 - k)/2. (2) Since ABCD is a rectangle, sides AB and BC must be perpendicular to each other...

You just need to calculate the scalar triple product a . (b x

**c**) which is equal to the absolute value of the 3x3 determinant | 1 1 -1 | | 1 -1 1 | | -1 1 1 | Expanding via the first row, I calculate it to be abs(1 x (-1 - 1) - 1 x (1 + 1) - 1 x (1 - 1)) = abs(-4) = 4 cubic units.1 Answers · Science & Mathematics · 11/09/2013
