You can model the populationof a certain city between the years 1995 and 2000 by the radical function P(x) = 55000 sqrt(x  1945). Using this model, in what year was the population of that city 275,000?
a. 1970
b. 1966
c. 1964
d. 1975

Best ResponseYou've already chosen the best response.0The 'BODMAS' concept tells u the order u should follow when simplifying. The order is from top to bottom. B= Brackets ( ) O= Of D= Divide M= Multiplication A= Addition S= Substraction

Best ResponseYou've already chosen the best response.0Okay, but if there is a square root sign, like this one, then how do I know what to do?

Best ResponseYou've already chosen the best response.0Oh sorry, then would I add 1945 to 25 and then it will give me x ?
