Has Mathematics helped find Malaysia Airlines Flight MH370?

March24

At the time of this post the search for debris (or anything) from Malaysian Flight MH370 is warming up, with new reports of objects floating in the southern Indian Ocean, far off the west coast of Australia. One difficulty with such searches is that, so long after the disappearance of the airliner, that objects in the water are most likely a long way from their point of origin.
AdriftLogoModelling base on real drift data has been compiled, by an Australian company, to gaphically show how two identical objects, when dropped at the same location in the ocean, can end up thousands of kilometers away from each other in a matter of a few weeks.

Update: British firm Inmarsat was behind an earlier analysis that indicated the plane had been flying in one of two big ‘corridors’, one in the northern hemisphere and one in the southern. However last week it went back to its data and tried a new mathematical analysis, which concluded on Sunday. This revealed that the plane had flown south. Read more here.

Prize Object Puzzle: If Sue does not know where the prize is in the first question, it can’t be under the square. She must have been told it is under another shape. Apply this same logic to Colin. It is then obvious that the prize cannot be under a yellow object. That helps Sue eliminate her yellow shapes. Got the idea?

Number of tabs? According to Lifehacker, the ideal number of tabs you should have open is nine. Yes, a single digit. To some, this is like playing a piano and only using a fraction of the notes!

Worst Graph? Where to start. What a visual mess and even some of the lines merge and are impossible to follow. A graph is a visual display of data, with the goal to identify trends or patterns. This is a spider’s web of information which fails to show a clear pattern at all. Solution? Well, different colors would help, or why not group in two or three graphs where trends are similar?

The graph on the left (Coronavirus) is for a time period of 30 days, while the one on the right (SARS) is for 8 months! Very poor graphical comparison and hardly relevant, unless it is attempting to downplay the seriousness of the coronavirus?

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)?]
