6 C 2  = 15

(I think!)

n=25.92 degrees

-6x-2y-2

85cm * 64cm * x cm = 92000 cm^3

x = 92000/(85*64) = 16.91 cm

One centillion + 1        LOL

Tan = 3/4 = sin/cos      remember   sin^2 + cos^2 =1    and  sqrt(sin^2 + cos^2) = 1

sqrt (3^2 + 4^2) = 5     but it should equal ONE   so the num and denominator need to be reduce by a factor of 5

tan = 3/5  /  4/5     Now   sqrt(sin^2 + cos^2)  = 1      

also   1-cos^2 = sin^2

1-(4/5)^2 = sin^2

9/25 = sin^2           which means sin = 3/5   or - 3/5   (.6  or -.6)  

g(x) = sqrt x    so g (4pi^2) = sqrt(4pi^2) = +-2pi

f(x) = sin^2 x    so f(+- 2pi) =  sin^2 (+-2pi) 

= 0

The highest  common factor of 12 and 18 is 6    He can make 6 identical arrangements each having 2 carnations and 3 tulips.

35100*.8 = 28080    Just use the calculator....

A=(a+b)/2  x h     where 'a' and 'b' are the parallel sides and 'h' is the distance between them.
