Math problems of the week
Yesterday, I went over to my friend Irene's after having dinner and $4 margerita's at the Harlem Blockheads. By the way that Blockhead's has great food but I think blasting the 90's crappy techno at 7 PM is a bit too much, especially since you can barely hear yourself talk.
Irene teaches math to 9th and 10th graders and she had to make a lesson plan for her class. While I waited, I thought for shits and giggles I'd do the worksheets she was going to teach. WOW. I can't believe how much I forgot. The first worksheet was a practice SAT and the second was all about the number i. I got 11 out of 16 right on the SAT and maybe 1 out of 10 right on the i :-( . Plus it took me like 20 minutes to do the SAT questions! That's disappointing since math was always my favorite subject, my best subject and I was a physics major!
Just to keep that part of my brain active I'll be trying out some random math problems throughout the week. Ok some might see it as me procrastinating on writing my screenplay, but I'm sure those synapses I'm going to rekindle will help with writing..... At least that's my excuse.
So here we go:
1. Factor completely. x2 - 6x + 9
2. Pythagorean Theorem: a=5; b=17; c= ????
3. Solve this quadratic equation : 200 = 8x2
Answers to be provided next week. Have fun!

for number 3
x = 5
because x squared = 200/8
= 25
x = 5 (5*5)
