Explanation Given Information: The prediction of an epidemic of influenza is done by,: d d t A = 1 10 A ( 20 − A ) Where, A is the number of people infected in millions and t is the number of months after the epidemic starts. If, 20 , 000 cases are reported initially. Shown by the substitution y = C L e − a L t + C where C is an arbitrary constant. Formula used: The provided differential equation has the form d y d x = a y ( L − y ) . A simple differential equation has the form d y d x = f ( x ) g ( y ) . Solve a separable differential equation by separating the x s and the y s algebraically, writing 1 g ( y ) d y = f ( x ) d x , And then integrating: ∫ 1 g ( y ) d y = ∫ f ( x ) d x . Calculation: Consider that prediction of an epidemic of influenza to follow the function as: d d t A = 1 10 A ( 20 − A ) Where, A is the number of people infected in millions and t is the number of month after the epidemic starts. If, 20 , 000 cases are reported initially Since, the solution for a differential pattern d y d x = a y ( L − y ) is y = C L e − a L t + C Where, C is an arbitrary constant Compare the provided equation d d t A = 1 10 A ( 20 − A ) with equation d y d x = a y ( L − y ) as: Then the value of a = 1 10 and L = 20 . If value of A is, A = C L e − a L t + C Put the value of a = 1 10 and L = 20 in A = C L e − a L t + C as: A = 20 C e − 2 t + C According to the given condition A = 0
