Calculus Homework Help. 1. The production of a chemical satisfies the following differential equation (dP/dt )= ((20)/(1 + 4t)^ 2 ), where t is time in days and P is the amount in moles. (a) Use integration by substitution
1. The production of a chemical satisfies the following differential equation (dP/dt )= ((20)/(1 + 4t)^ 2 ), where t is time in days and P is the amount in moles.
(a) Use integration by substitution to find the solution, P(t), starting from the initial condition P(0) = 0.
(b) Sketch the rate of change ( dP dt ) and the solution.
(c) What happens to P(t) as t → ∞?
3. An outbreak of a novel infectious disease is initially growing at a rate of f(t) = 1.5e 0.12t
new cases per day (where t is time in days).
(a) Evaluate a definite integral to find the number of new cases that occur during the first 2 weeks.
(b) What’s the average number of daily new cases in the first 2 weeks?
(c) If the rate was initially given by g(t) = 1.5 + 0.12t new cases per day (where t is time in days), how many fewer cases would occur during the first 2 weeks?
