Answer:
the answer is c because the diameter is 20 and half of the circumference will be around 60
I’m sure it’s the last one D
The general form of sine curve is f(x) = a sin (nx)
Where: a is the amplitude and n = 2π/period
Given the points of the sine curve which is
(0, 0) and (160, 1) and (320, 0) and (480, -1) and (640, 0)
the maximum value of f(x) = 1 , and the minimum value of f(x) = -1
∴ amplitude = a =1
And the function complates one cycle from 0 to 640
∴ period = 640 ⇒⇒⇒ n = 2π/640 = π/320
∴ f(x) = 1 * sin (π/320)x = sin (π/320)x
∴ The correct answer is option d
