Suppose $Q=Ce^{kt}$ satisfies the differential equation $$\frac{dQ}{dt}=-0.08 Q.$$ What (if anything) does this tell you about the values of $C$ and $k$?

Either:
$C =$ , and
$k =$
(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:
$C =$ , and
$k =$
(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.)
