Cheers.

While researching the task, what steps did you take to ensure that your information and data was accurate, reliable and valid? Any ideas. Please help with something. It's really hard for me to understand.

Make your notes as simple as possible. Do practise tests.

Um, ask if you can not do the preliminary exams. That way, they'll give you averages based on your performance on earlier assessment tasks. In the end, year 11 marks don't go anywhere. Remember a doctor's certificate when explaining your absense from exams and school. Just try and get better...

We're doing identity.

Lyounamu, I thought it was a given that you would be doing extension 2 mathematics. ;) You definitely have the ability. Definitely.

Wow Conics. Nice work. Our school's highest was 61%.

You are right. It's not technically the same but the difference between 2 kelvin is the same as the difference between 2oC if that makes sense. So the temperature change units are interchangable between oC and Kelvin. http://www.answers.com/kelvin&r=67

Why? Those two minutes of my life would've been spent procrastinating anyway.

Draw a diagram on the number plane. Let the vertex of the parabola be the point (0, 0). The diameter of the dish is 4m so draw a line 2 units each left and right horizontal to the x-axis through the y point of 0.4 (to ensure the depth is 0.4m). Use the equation: x2 = 4ay (since the parabola...

3 unit = 76/84 = 90% ---> Aligned to 95% I reckon. 4 unit = 102/120 = 85% ---> Aligned to 95% I reckon.

:uhhuh: If you like them both do the one that will get you a better UAI/marks.

Like any subject. Constant revision and completing set work.

But remember the surface area of cylinder can be figured out through the differentiation of the volume of a cylinder. V = pi.r2.h dV/dr = 2.pi.r.h <---- Equals the rectangular part wrapping around shape. Then just add on the circles that enclose the cylinder: S.A = 2.pi.r2 + 2.pi.r.h.

Aerath is correct. Just to clarify. ΔH = -mCΔT change in heat energy (kJ) = -mass of water (kg).specific heat capacity of water (4.18kJ/kg/K).change in temperature of solution(K) If you wanna get mathematical (here's a sort of proof): ΔH = -mCΔT kJ = kg.(kJ/kg/K).K <----...

64 and 81. 64 from ratio of side of square to square root of number of squares on the border. >5:4 = 10:x 4/5 = x/10 x = 8 > Then square 8 = 64 81 if you take each as a perfect square; > Square root of squares on border is one less than side of square grid 52 for grid (5-1)2 = 42...

Did you guys know the differentiation of the formula of the volume of a 3D shape gives the formula of its surface area? E.g. V = 4/3pir3 = volume of sphere dV/dr = 4pir2 = surface area of sphere

How? Why? Care to elaborate? What instrument/voice? What piece of music?
