x = A sin â¡ ( Ï [ t â K ] ) + b , {\displaystyle x=A\sin(\omega [t-K])+b\ ,}. 1  A is the amplitude (or peak amplitude), 2  x is the oscillating variable, 3  Ï is angular frequency, 4  t is time, 5  K and b are arbitrary constants representing time and displacement offsets respectively.
Modeling agency. A modeling agency is a company that represents fashion models, to work for the fashion industry. These agencies earn their income via commission, usually from the deal they make with the model and or the head agency. The top agencies work with big-budget advertising agencies and fashion designers.
Part-timers and men make less. It mainly depends on what kind of modeling. The more work that is booked, the more money a model can make, however, the salary of the average working model is around $30,000 a year. But some get paid $40,000 a year if you are working for an agency in new york, L.A., and or miami. A & F models get paid about the same amount as a regular editorial or fashion model. They can make $150 an hour or higher but in general, make less than $25-30k a year.
