DNA Revisited – Mathematical Proof of Divinity?

March1

A single cell and the DNA that causes it to function is millions of times more intricate than anything man has created. So, is it mathematically possible for us to not be created by a higher power? For illustration purposes, let’s take a 200 page book. Could the cover, the paper, the ink and the […]

Did You Know … DNA factoid

February25

DNA, the long molecules containing our entire genetic blueprint, are about two metres long when unwound, but pack into cell nuclei that measures only 100th of a millimetre across.

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)?]
