Answer: 
Step-by-step explanation:
If we model the clock as a circumference, we will be able to see that a complete turn (the whole circumference) represents 
, hence:
Now we have to find the equivalence between 
and 
and degrees. So, in order to do this, we can make a Rule of Three:
For :

Answer:
23
Step-by-step explanation:
Maybe you want to evaluate ...
f(x) = 3x^2 -2x +7
for x = -2.
Put the value of x where x is, then do the arithmetic.
f(-2) = 3(-2)^2 -2(-2) +7 = 3(4) +4 +7
f(-2) = 23
