The problem is: S = an^2 + bn Where a and b are constants. Possible values for S are: 6, 15, 27, 42 and 60 Possible values for n are: 1 when S=6, 2 when S=15, 3 when S=27, 4 when S=42 and 5, when S=60. I am asked to find the values of a and b. The way I tried to tackle it was...

I might not be the brightest bob in the bunch but I am having trouble with a simple quadratic equation. k^2 + (k + 4)^2 = 346 According to my manual expands to: k^2 + k^2 + 8k + 16 = 346 Everything is going fine until I see the 8k. Where did the 8k come from? Or is my...

Thanks mate. Initially I tried it with -0.6 m/s/s but still came out with a nonsense answer. My problem it seems is the mathematics of the problem and being able to isolate "d". I left school a long time ago and have a vague memory of how to solve basic equations, thankyou for clearing the...

Sorry to waste your time on wot should be a simple question: A boat is traveling at 30 metres per second and begins to decelerate at 0.6 metres per second/per second. How much distance would it cover ( in metres) would it cover before it comes to a compete stop? I have tried solving this...
