B I’m guessing, never really worked with something like this before though
Answer:
352 cm/s
Step-by-step explanation:
circ = 44pi
speed = distance * time
distance = circ * 4 = 176pi
speed = 176pi/0.5
We saw under Functional Notation that y = 3x + 2 and f (x) = 3x + 2 can be interpreted as equivalent notations, where y has been replaced by f (x), or y = f (x). In y = 3x + 2, we see “y as a function of x”
You were right, its the second choice CA=CB+BA
101.65 x .30= 30.50 saving
so take 101.65 - 30.50= 71.15
