(dy)/(dt)= 9/40-y/(200),y(0)=90

Lösung

\frac{d y}{d t} = \frac{9}{40} - \frac{y}{200}, y (0) = 90

y = 45 + \frac{45}{e ^{\frac{t}{200}}}

Schritte zur Lösung

\frac{d y}{d t} = \frac{9}{40} - \frac{y}{200}

Solve linear ODE:

y = 45 + \frac{45}{e ^{\frac{t}{200}}}

y = 45 + \frac{45}{e ^{\frac{t}{200}}}
