You'll need the 3 hours. (so I've heard)

yeah, i'm so nervous too

Okay next one 5:06 Question 11.a ( curves of the form y=ax^3+d ) Find its equation: It's a positive curve that passes through points (0,10) and (2,20) Look at the coordinate (0,10). THis means that the y intercept is 10. Hence, the d in your equation is 10. y = ax^3 + 10. Substitute (2,20) in...

Hence, my uai aim of 80+ when I should, indeed, be aiming for 90+

Sum of numbers from 1 to 200: 200/2(1+200) = 100 x 201 = 20100 6, 12, 18, 24..... sum of numbers divisble by 6: 33/2[2x6 + (33-1)6] = 3366 sum of numbers from 1 to 200 that are not divisble by 6: 20100 - 3366 = 16734 Correct me if I am wrong :p (pretty sure it's wrong)

The Board is crazy for implementing an easier General course. :p
