Question 1117094: On a certain isolated beach the population of a certain shellfish and sea birds were being studied over a number of years.the shellfish were at a risk if there population fell lower than 1900 and they were at a risk If the seabird population was greater than 1300 and was greater than the shellfish population. The number of each species can be modelled by doing the sine and cosine graphs.
The shellfish had a population that was at a peak two years after the study began. The maximum order of shellfish population peaked every four years. The sea bird population peaked every nine years with a minimum of 620 and a maximum of 1780. The number of seabirds began to increase from an initial number of 1200 birds. What is the equation of the shellfish and seabird population?

This sounded like it might be an interesting problem, so I spent way too much time trying to figure out what the given information really was. Unfortunately, with the misspellings, bad punctuation, and the use of some words that don't make any sense at all, I was unable to glean enough information to have a chance of solving the problem.
There is enough information about beginning population, minimum and maximum populations, and period length to find a sine or cosine function for the bird population.
But I found no useful information for finding a function for the shellfish population.
If the two populations can be represented by sine or cosine graphs, then all the given information about the risk to the shellfish population is irrelevant; and that leaves no information at all about the shellfish population.
It's really a shame that you were unable to present the problem in a way that it could be solved.
