Answer:
y(t) = 13[1 - e^(-6t)]
does not satisfy the differential equation,
dy/dt = 6(13 - y)
Step-by-step explanation:
Given
y(t) = 13[1 - e^(-6t)].....................(1)
We want to show that this function satisfies the differential equation dy/dt = 6(13 - y).........................(2)
If (1) is a solution of (2), then after differentiating (1) with respect to t, we obtain dy/dy, and substituting the value obtain for dy/dt into (2), (2) is satisfied. Otherwise, it doesn't not satisfy (2).
Now, let us do that.
y(t) = 13[1 - e^(-6t)]
Differentiating with respect to t, we have:
dy/dt = 13×(-6)[1 - e^(-6t)]
= -6×13[1 - e^(-6t)]
But y = 13[1 - e^(-6t)]
So,
dy/dt = -6y
Therefore,
y(t) = 13[1 - e^(-6t)]
does not satisfy the differential equation,
dy/dt = 6(13 - y)
