How did you get 16t^2?
A zombie steps off a 35-foot wall by mistake, landing in the river below. How long will it take the zombie to fall?
Check the site that Elena gave the lenntech one -it gives chemical properties. Pretty detailed, too.
Go to Google --> Periodic table ---> properties. Not that hard -.-
Thanks a ton!
Show that if A, B, and C are the angles of an acute triangle, then tan A + tan B + tan C = tan A tan B tan C. I tried drawing perpendiculars and stuff but it doesn't seem to work? For me, the trig identities don't seem to plug in as well. Help is appreciated, thanks.
a*z^2 + b*z^2 + a*z^3 + b*z^3 reorder: a*z^3 + b*z^3 + a*z^2 + b*z^2
the pattern is 2, 4, 6, 8, ..... 2+4+6+8+10+12+14+16+18 = 90 Thus for the next, there will be 10 red and 10 green. So, there will be 10 more red than green: x+y = 100 x=y+10 y = 45 x = 55 So, x, or the number of red beads is 55
If I don't misunderstand, it means "What does the news say about the subject/topic?"

Yay thanks man for the help
