>>Just tried to do the 2009 exam as fast as I could.
Finished it in 21 minutes and 50 seconds. Scored 95%. lols
Pretty sure the times are the same everywhere. Mine are at 9 or 9:30 I think.I'm so pumped for Tuesday. Does anyone know the times of the exams or is it different from school to school.
tan90 is undefined as on a graph it runs 0, and since tan=gradient=rise/run, tan90 needs to divide by 0, which is undefined.Im not sure if this is SC worthy but...
Explain why tan90 is undefined (i.e. plug into calculator it becomes a math error)
If not then Ill try something safer with this.
(1). The shorter my hair is the faster is will grow, likewise the longer my hair is the slower it will grow. If there was a curve to describe my hair growth, describe the gradient of the curve.
OR
(2). True/False
a. A rhombus is a square
b. A square is a rhombus
(3). 3+5*9+(4-2)= ?
455% of a people are flying first class
15% Are flying business class
the rest of the plane is economy class
Is 240 people flew economy class, how many flew business class?
The graphs y=ax and y=2x ALWAYS intersect at the originax=2x
x(a-2)=0
x=0 and 2 ?
http://www.wolframalpha.com/input/?i=y=5000xY=5000x does not intercept the origin. I agree with 2, 0
i think that is the question and yeah it is for all values of x.Awesome and all correct:
How about another question:
I have two lines:
y=ax
y=2x
The lines intersect at the origin, what values for a are there?
NOTE: This question is more simpler than you might think
Total number of people flying=240/(100-15-5)*100=300 people5% of a people are flying first class
15% Are flying business class
the rest of the plane is economy class
Is 240 people flew economy class, how many flew business class?
