Scribepost for February 24th, 2009

Tuesday, February 24, 2009
Today in class, Mr. Harbeck wasn't there in the morning so we just corrected the homework from yesterday with Mr. Bartz. Well, we learned more about the pythagorean theorum (a2+b2=c2).

For homework we got 4 triangles with a side that is not solved yet but I am only going to explain to you 2 of them.




(The 2's mean squared)

c2-a2=b2

10 2-6 2=b2

100-36=b2

64=b2

find the square root of 64 which is 8 and the way you can find that is by using a calculator.

8=b

(The 2's still stand for squared)

c2-a2=b2

50 2-30 2=b2

2500-900=b2

1600=b2

The square root of this is 40.

40=b

This is a video I found. It is also one of the videos Mr. Harbeck showed us last week.

The next scribe is Robin. If he did already, then I pick Richard.
