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)
