In 1970 the population of the United States was 203 million. Ten years later, in 1980, the population of the United States was 226 million.
Write a function for the exponential growth of population in the U. S using:
-t(0)=203
-t(0)=226

You can model the population of a certain city between 1955-2000 by the radical function p(x)=55,000 sqrt x-1945. using this model, in which year was the population of that city 220,000

F(x) = 1/x g(x)=x-4 can you evaluate (g*f)(0) ? why or why not?

Afarmer has a large field that is x feet in length. he wants to fence in a rectangular section in the middle of the field , leaving a length of 100 feet of open field behind each end of the fenced rectangle.he also wants the width of the fenced-in space to be 100 feet less than its length. find the expressions to represent the length and width of the fenced section of the field
