Explanation Given: The given initial boundary value problem is: y ″ − 4 y ′ + 13 y = 0 ; y ( 0 ) = 0 , y ( π ) = 0 Procedure used: Solution for homogeneous equation: Consider the equation, a y ″ + b y ′ + c y = 0 . First find the roots of the auxiliary equation: a r 2 + b r + c = 0 If the roots are conjugate complex α ± β i , then the general solution form is: y ( x ) = c 1 e α x cos β x + c 2 e α x sin β x After that, use the initial condition to find the value of the constants in the general solution. Quadratic formula for finding the roots: − b ± b 2 − 4 a c 2 a Here, a, b and c are coefficients of the quadratic equation. Calculation: Consider the given initial boundary value problem: y ″ − 4 y ′ + 13 y = 0 ; y ( 0 ) = 0 , y ( π ) = 0 The auxiliary equation is: r 2 − 4 r + 13 = 0 Find the roots of the equation by using the quadratic formula: r = − ( − 4 ) ± ( − 4 ) 2 − 4 × 1 × 13 2 = 4 ± 16 − 52 2 = 4 ± − 36 2 = 2

Suppose that a room containing 1300 cubic feet of air is originally free of carbon monoxide (CO). Beginning at time t = 0, cigarette smoke containing 4% CO is introduced into the room at a rate of 0.8 cubic feet per minute. The well-circulated smoke and air mixture is allowed to leave the room at the same rate. Let A(t) represent the amount of CO in the room (in cubic feet) after t minutes. (A) Write the DE model for the time rate of change of CO in the room. Also state the initial condition. dA dt A(0) (B) Solve the IVP to find the amount of CO in the room at any time t > 0. A(t) (C) Extended exposure to a CO concentration as low as 0.00012 is harmful to the human body. Find the time at which this concentration is reached. t= minutes
