Calculus population growth problems
WebTo find the population you can integrate: Let R = radius of city; Since x 2 + y 2 = R 2 ,then y = 25 − x 2; since you are only evaluating 1 4 of the circle multiply the integral by 4; let r = x; and you get the Integral ∫ 0 5 4 25 − x 2 ⋅ ( 20 − 4 x) d x I think this is correct. Let me know if I am wrong. Share Cite Follow WebWhat we could do is find the population 𝑃 (𝑡) as the indefinite integral 𝑃 (𝑡) = ∫𝑃 ' (𝑡)𝑑𝑡 = (1∕1.2)𝑒^ (1.2𝑡) − 𝑡² + 𝐶 Then, since we know 𝑃 (2) = 1500 we can use that as the initial condition and find 𝐶: 𝑃 (2) = (1∕1.2)𝑒^2.4 − 4 + 𝐶 = 1500 ⇒ 𝐶 = 1504 − (1∕1.2)𝑒^2.4 ≈ 1494.81 Thereby, 𝑃 (5) ≈ (1∕1.2)𝑒^6 − 25 + 1494.81 ≈ 1806.00
