Suppose Q=Ce^kt satisfies the differential equation dQ/dt = -0.02Q
What (if anything) does this tell you about the values of C and k?
a) 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.)
[I got C=anything, k=-.02 and it is right]
b) 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.)
[I got a) C=anything, k=-.02 and it is right but I don't know how to do part b]

dQ/dt = -.02Q
dQ/dt = Ck*e^(kt) = -0.02C*e^(kt)
k = -0.02
dQ/dt = Ck*e^(kt) = -0.02C*e^(kt)
k = -0.02
