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.
Most new models learn quickly that an agency will generally take 20% of your earnings as their fee for getting you the job. What many models donât figure out for a long time is that agencies also generally charge the client a âbooking feeâ for finding them the right model. Example: If the job pays $1,000. As the model your earnings will be $800.00 if the agency takes a 20% fee. The client however will actually pay $1,200 for the booking.
