Complete Question:

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 275,000?

Answer:

In 1970 population of that city is 275,000

Solution:

Given that,

You can model the population of a certain city between 1955-2000 by the radical function :

P(x) = 55000\sqrt{x - 1945}

To find: year in which was the population of that city 275,000

Therefore,

x = ?

P(x) = 275000

Thus we get,

275000 = 55000\sqrt{x - 1945}\\\\Divide\ both\ sides\ by\ 55000\\\\\frac{275000}{55000} = \sqrt{x-1945}\\\\5 = \sqrt{x - 1945}\\\\Take\ square\ on\ both\ sides\\\\25 = x - 1945\\\\x = 1945 + 25\\\\x = 1970

Thus, in 1970 population of that city is 275,000

The answer is A. 1970.

Answer: Year 2000 Explanation: Using the radical function P(x) = 55,000./7-1,945, we can determine the population for a certain city at different years. To find the year in which the population is 275,000, we can rearrange the equation to make x the subject. This equation becomes x = 7(55,000/P(x)) - 1945. Substituting our population of 275,000 in the equation gives us x = 2000. Therefore, the population in the certain city was 275,000 in the year 2000.

He took out a pile of shirts and began throwing them, one by one, before us, shirts of sheer linen and thick silk and fine flannel, which lost their folds as they fell and covered the table in many- colored disarray. While we admired he brought more and the soft rich heap mounted higher-shirts with stripes and scrolls and plaids in coral and apple-green and lavender and faint orange, with monograms of Indian blue. Suddenly, with a strained sound, а Daisy bent her head into the shirts and began to cry stormily. It reveals Daisy's respect for Gatsby and how much he has accomplished since they last met. "They're such beautiful shirts," she sobbed, her voice muffled in the thick folds. "It makes me sad because I've never seen such- such beautiful shirts."
