Mathematics helps design wind turbines

November11

Mathematics contributes in many ways to the process of converting wind power into usable energy. For example, mathematical weather models are used to find suitable locations for wind farms, while other models specify how to place individual turbines within a farm. Finally, Mathematics (through the use of fluid dynamics) describes air flow and drag around […]

Air Traffic Controller – Math Career

March31

Air traffic controller uses math in order to be able to understand distances and measurements at a moment’s notice. They also must be able to do mental math quickly and accurately. Part of their job is directing aircraft at what altitude and speed to fly. An error in these directions could be fatal so a […]

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)?]
