2. ### what is 5k divided by -k?

k-8/7+k = -1/5 okay :P afraid? maths <3 awesome :P love XD 5(k-8) = -1 (7+k) 5k - 40 = -7 - k 5k+k= -7 + 40 6k = 33 k= 33/6

3. ### Show that p_k = p_(k-1) + (3k-2) for k >=2. Conclude that p_n = sum from k=1 to n of (3k-2).?

Let k ≥ 2. Then p_(k - 1) + 3k - 2 = (k - 1)[3(k - 1) - 1]/2 + (6k - 4)/2 = [(k - 1)(3k - 3 - 1) + 6k - 4]/2 = [(k - 1)(3k - 4) + 6k - 4]/2 = (3k² - 7k...

4. ### k-4 divided by 9=3 help me?

k-4/9=3 you want to isolate k to find the answer, so you have to do the operations in reverse. so k-4=3x9 k-4=27 k=27+4 k=31

5. ### 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...

7. ### From the formula, k(x)=2sin(x+pi)/(sin(x+pi)-3), what is k^-1(x)?

k(x) = 2 sin (x+π) / (sin (x+π) - 3) = 2 (- sin x) / (- sin x - 3) = 2 sin x / (sin x + 3) = [2 (sin x + 3) - 6] / (sin x + 3) = 2 - 6 / (sin x + 3) So for k^-1(x) we get x = 2 - 6 / (sin k^-1(x) + 3) => 6 / (sin k^-1(x) + 3) = 2 - x =>...

9. ### Closed form for 1/(k x (k+1) x (k+2))?

Decomposing 1/[k(k+1)(k+2)], you have: A/k + B/(k+1) + C/(k+2) = 1/[k(k+1.... Therefore: A(k+1)(k+2) + B(k)(k+2) + C(k)(k+1) = 1 which must hold true for all valid values of k. To determine...
