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.
I did a big campaign for New Look and was in all of their shops. It must have totalled around Â£35,000 over about seven years. Now I'd say most regular models are getting paid less and less for more and more work. You're expected to do longer hours and do the whole social media thing. If you have fewer than 10,000 followers on Instagram you'll lose the job to someone with more followers, as they can give the brand a broader advertising reach.
