The circumference involves 360 degrees.
60 degrees is one sixth of the circle (60/360)
So, one sixth of 72 is 12.
For an exponential function the y-intercept is the "initial value" (not the common ratio).

will always be 2. if that's what you need
note that

because anything to the power of zero equals 0 (mathematically it's deciding something by itself)
Step-by-step explanation:
Note the system of equation, PEMDAS. First, you solve parenthesis, then multiplication, then subtraction.
In this case, solve each of the expression given to us. Remember that parenthesis is first:
(12 - 23) * 2 = (-11) * 2 = - 22
12 - (3 * 2) = 12 - (6) = 6
- 22 ≠ 6
