The distance the tip travels is
2π·(40 m) = 80π m
Then its speed is
(80π m)/(10 s) = 8π m/2 ≈ 25.1 m/s
From reading the problem we see that y = 0 and x = 16.
To find the correct equation, simple plug in the values for x and y for each equation and see which equation is true.
The correct answer is 5x + 4y = 80
5(16) + 4(0) =80
80 + 0 = 80
80 = 80
Answer:
y = -2x - 3
