During the morning we started to work out some problems that we had from the last homework that everybody had troubles with.
From the homework Exercise sheet
#2.
Determine the equation of the circle which passes throguht the points
J(-3,2) k(4,1) L(6,5).
Points:
J(-3,2)
k(4,1)
L(6,5)
this is an example of how we know where the centre is
( spelling error know = knowing )
we have to find the midpoint.
So we used Rise/Run
Rise/run
m(KL)= 4/2 = 2
m(AL)= -1/2
midpoint
midKe=(5,3)
y-3=-1/2(x-5)
After that the whole class has to do the paper folding again, this time for the "Hyperbola"
Here was a sample of what it turn out to be:
After that we had to calculate what line measures up to.
Pf1 - Pf2 = 56mm-135mm = 79
Qf1-Qf2 =146mm-69mm = 77
Rf1-Rf2 =143mm - 69mm = 76
A1A2= 81
( note: my calculations are different from other students)
During the afternoon mr.K was away , so we just did a quiz & homework on exercise 38
well by3 everyone , next person would be : JOHN!!!!!
