Suppose $Q = Ce^{kt}$ satisfies the differential equation
$\frac{dQ}{dt} = -0.09Q$.
What (if anything) does this tell you about the values of $C$ and $k$?
Either:
$C = \text{ }$ and
$k = \text{ }$
(For each of $C$ and $k$, enter the value that the parameter must take, or enter the word anything if there are no restrictions on the value.)
or:
$C = \text{ }$ and
$k = \text{ }$
(For each of $C$ and $k$, enter the value that the parameter must take, or enter the word anything if there are no restrictions on the value.)
