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

  1961

Step-by-step explanation:

Put the given information into the equation and solve for the unknown.

  220,000 = 55,000√(x -1945)

  4 = √(x -1945) . . . . divide by 55,000

  16 = x -1945 . . . . . . square both sides

  1961 = x . . . . . . . . .  add 1945

The population was 220,000 in the year 1961.

answer: i believe c. is the answer sorry if i am wrong

step-by-step explanation:

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
