d/dx (sin2x) = 2 cos 2x
V of sphere = 4/3 pi r^3
4/3 pi r^3 = 36 pi divide both sides of eq by pi
4/3 r^3 = 36 multiply by 3/4
r^3 = 27 Cube root
r = 3
diameter = 2*r = 6 cm
5000 * .15 x 1/2 = $375 each 6 months
Tan = sin/cos
1/tan = cos/sin = cot
16 + 16 + 2 sqr(12^2 + 9^2) = 62 Using pythagorean theorem to find the missing side(s)....
Where can I get a helicopte for 64,600 ! ? I want one!
SIn (pi - 32) = sin 32 so sin 148 = sin32 = a
cos(pi-32) = -cos(32) so cos(148) = -b
tan (148) = sin(148) / cos(148) = -a/b
Add eq 1 and 3
-x + 3z = 8 (4)
Multiply eq 2 by 3 and add it to eq 3
-11x +16z=37
Multiply (4) by -11 and add to (5)
-17z= -58 so z=3 Sub into (4) to find x = 1
Sub these into any of the equations to find y
x+3y +2z =1
1 +3y +2(3) = 1 thus y = -2
.....using dimensional analysis 18hr * $ 9.45 / hr = $ 170 .10 (don't forget units )
The greatest common divisor of 60 72 and 36 is 12 boxes
