0.15 × $3,559.07 = $533.86
Coefficients, constant doesn't matter in period. only the "argument" or parameters or the angle matters.
if has a period $T$ then $cf(ax+b)+d$ will have period of $\frac Ta$ (nothing matters other than that), $T$ is the fundamental period.
$\sin(x)$ has fundamental period is $2\pi$ so period of $fx)$ will be $\pi$
I do not think so, but i’m not 100% sure
