You can model the population of a certain city between the years 1965 and 1995 by the radical function P(x) = 75,000 ^3sqrt x-19
LuckyWell [14K]

Answer: B. 1975


Step-by-step explanation:

Given:  The model of population of a certain city between the years 1965 and 1995 by the radical function

P(x)=75000\sqrt[3]{x-1940}

To find the x year at which population is 245,000, put this in equation we get

245000=75000\sqrt[3]{x-1940}\\\\\Rightarrow\frac{245000}{17000}=\sqrt[3]{x-1940}\\\\\Rightarrow3.266=\sqrt[3]{x-1940}\\\\\Rightarrow\ x-1940=(3.266)^3..........\text{[by taking cube on both sides]}\\\\\Rightarrow\ x-1940=34.8587\\\\\Rightarrow\ x=1940+34.8587\\\\\Rightarrow\ x=1974.8587\approx1975

Hence, at year 1975 the population of the city is 245,000.
