.075 x mole = .075 x Avagadro's Number
= .075 x 6.022 x 10^23 = 4.517 x 10^22 ions
....And also , I think
sqrt(-2) x sqrt(-12) = i sqrt 2 x i sqrt 12 = i^2 sqrt(24) = i^2 (2) sqrt 6 = -2 sq rt 6
Remember:
S-O-H-C-A-H-T-O-A
Sin = Opposite/Hypotenuse
Cos=Adjacent/hypotenuse
Tan=Opposite/Adjacent
Area calculations difer for each type of figure
Circle = pi x r^2
triangle = 1/2 b x h
square or rectangle = l x w
etc....
Of what type of figure are you interested in finding the area????
2/3 x^2 = 6 Multiply both sides by 3/2
x^2 = 9
x = +3 or -3
Take the area of the larger circle with the radius of 50 +10
then subtract the area of the circle with the radius 50
....and go ONE step further.....make the perimeter a CIRCLE to maximize the enclosed area......FWIW.
Seven trillion eighty one billion.
ONE more (though not as good as the others)
If the duck 'crossed' at an angle greater than 180 degrees, it wouldn't need to use any 'reflex' to dodge cars!
I'm reading 'this' and all I can see is that "you're" not very good with English ! LOL
