Imagine a right triangle where a and b are the legs and c is the hypothenuse.
Pitagora: a²+b²=c²
Divide by c
(a/c)²+(b/c)²=1
But a/c=sin(B) and b/c=cos(B)
Thus sin² + cos² = 1
Your function is:
Y= 29 + 0.35x
X represents the money that Tracy is charged per minute
2 x 10 x 7 = 7 x 10 x 2 = 10 x 2 x 7 = 7 x 2 x 10
