What correlates to happiness?
Tijne Schols, The Hague, The Netherlands Maslanka’s answers 1 Let 4/x + x = V. Multiply both sides by x: 4 + x2 = Vx, or x2 – Vx = –4. Add (V/2)2 to both sides: x2 – Vx + V2/4 = V2/4 – 4. The left-hand side is (x – V/2)2 and this must be positive; hence V2/4 = 4 ≥ 0, too.2As V must be positive, V ≥ 4. For p /x + 1/x, we have similarly a minimum value of 2p (when x = p); for x = p/x + 1/x, it’s 2√p (for x = √p); p is positive. 2 Square out the brackets: (pq)2 + (rs)2 – 2pqrs + (ps)2 + (qr)2 + 2pqrs = (pq)2 + (rs)2 + (ps)2 + (qr)2. We then recognise this as (p2 + q2)(r2 + s2). 3 Wordpool a) 4 Same Difference RAISE, PRAISE 5 Missing Links a) lips/tick/box; b) dead/line/dancer; c) single/ market/trader; d) ceiling/rose/ water; e) table/top/secret; f) almond/milk/chocolate.
