1978/3

= $\frac{1978}{3} miles/hour$

Use the button under the '1/x' button

I think you meant pi, not pie.

$π=\frac{circumference}{diameter}$

OR

$π = \frac{1}{2}\frac{circumference}{radius}$

15P2 = 210

210 ways

e is the amount of energy

m is the mass

c is the how far light can travel in 1 seconds in a vacuum (Speed of light)

51.1 = 8000^3(a)

a = 51.1 / (8000^3) ≈ 9.98046875 x 10^-11

Press the '2nd' button and look for where the '÷' sign, and you get modulus button! 

area = 1/2 x b x c x sin A = 1/2 (6)(3)(sin 50) = 9 sin 50 ≈ 6.894 square ft

${-b \pm \sqrt{b^2-4ac} \over 2a}$

It is the solution to any quadratic equations ax²+bx+c=0
