### America’s Cup by the Numbers

September25

The Formula 1 of yachting – the America’s Cup. Outstanding technology where the boats are now sailing over twice the speed of the wind. Also a victory as Oracle came from 1-8 wins behind to beat Team New Zealand 9-8. How did this ‘one of the greatest comebacks in sport’ happen? It was all down […]

Researchers from the Miguel Hernández University of Elche have used mathematical techniques and game statistics from the Association of Tennis Professionals (ATP) to rank tennis players based on assessing their play. Their results complement the ATP ranking obtained on the basis of matches […]

10 x 9 x 8 + (7 + 6) x 5 x 4 x (3 + 2) x 1 = 2020

NCEA Level 2 Algebra Problem. Using the information given, the shaded area = 9, that is:
y(y-8) = 9 –> y.y – 8y – 9 =0
–> (y-9)(y+1) = 0, therefore y = 9 (can’t have a distance of – 1 for the other solution for y)
Using the top and bottom of the rectangle,
x = (y-8)(y+2) = (9-8)(9+2) = 11
but, the left side = (x-4) = 11-4 = 7, but rhs = y+? = 9+?, which is greater than the value of the opp. side??
[I think that the left had side was a mistake and should have read (x+4)?]
