3. ### For what values of the constant k will the following function NOT be its own inverse.?

Let (x - k) / (x - 1) = y x - k = yx - y x = yx - y + k x - yx = y + k x(1 - y) = y + k x = (-y + k) / (1 - y) x = (y - k) / (y - 1) It would seem that the function is generally its own inverse...

5. ### How do I factor 3x² 16x k?

You can't. You have to know what k is. That said, if you have other conditions which...like: (3x + m)(x + n) where m and n are integers, and: mn = k m + 3n = 16 ==> m = 16 - 3n k = n(16 - 3n) = 16n - 3n² So, pick...

7. ### Prove If K is convex, then cl(K) is convex?

Let K be a convex subset of R^p and let x,y be in the closure of K. Then there exist sequences (x_n), (y_n) of points in K such that lim x_n = x and lim y_n = y. The line segment between x_n and y_n...

10. ### given that 1^2+2^2+3^2+.....+k^2=k*(k+1)*(2k+1)/6,what is the smallest integer k such that?

k(k+1)(2k+1)/6 must be divisible by 100 means k(k+1)(2k+1) divisible by 600 which is 5x5x2x2x2x3 2k+1 is odd, and only one of k or k+1 can be even so you need k or k+1 divisible by 8 one of k, k+1, and 2k+1 will always be divisible...
