<span>y = -5 cos x is a basic (simple) variation of the basic trig function y = cos x.
The given </span>y = -5 cos x could be re-written as <span>y = -5 cos 1x.
Compare this to the most general form: y = a cos bx.
Here we see that the coefficient b equals 1.
There is a rule for finding the period of such a function: Period = 2pi/b.
Since b = 1 here, the Period here is 2pi/1, or simply 2pi.
Please stop saying "I'm terrible with math." That does not help you at all. Say, instead, "With just a little help I could understand this just fine."</span>

Answer:
The Greatest Common Factor (GCF) for 56 and 84, notation CGF(56,84), is 28.
Step-by-step explanation:
The factors of 56 are 1,2,4,7,8,14,28,56;
The factors of 84 are 1,2,3,4,6,7,12,14,21,28,42,84.
So, as we can see, the Greatest Common Factor or Divisor is 28, because it is the greatest number that divides evenly into all of them.
