Let the Universal set be the letters a through j: U = {a, b, ..., i, j}. Let A = {a, c, h, i}, B = {a, d, h, j}, and C = {a, c, d, g}

List the elements of the set
A ∩ (B ∪ C)

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?

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 :

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

Therefore,

x = ?

P(x) = 275000

Thus we get,

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