Q:
# The birth rate of a population is b(t) = 2300e0.024t people per year and the death rate is d(t)= 1450e0.019t people per year, find the area between these curves for 0 β€ t β€ 10. (Round your answer to the nearest integer.)

Accepted Solution

A:

Answer:Area = 10025.66 square unitsStep-by-step explanation:We are given the following in the question:The birth rate of a population:[tex]b(t) = 2300e^{0.024t}[/tex]The death rate of a population:[tex]d(t)= 1450e^{0.019t}[/tex]The area between the curve for 0 β€ t β€ 10, is given by:[tex]\displaystyle\int_0^{10}b(t) - d(t)~ dt\\\\\displaystyle\int_0^{10} 2300e^{0.024t}-1450e^{0.019t}~dt\\\\= \Bigg[\frac{2300e^{0.024t}}{0.024}\Bigg]_0^{10}-\Bigg[\frac{1450e^{0.019t}}{0.019}\Bigg]_0^{10}\\\\= \Bigg[\frac{2300e^{0.24}}{0.024}-\frac{1450e^{0.19}}{0.019}\Bigg]-\Bigg[\frac{2300}{0.024}-\frac{1450}{0.019}\Bigg]\\\\= 29543.2058565 - 19517.5438596 \approx 10025.6[/tex]
