Suppose y(t)=9e^(−5t) is a solution of the initial value problem y′+ky=0, y(0)=y0. What are the constants k and y0?

OpenStudy (turingtest):

plug y(t)=9e^(−5t) into the differential equation and what do you get?

OpenStudy (anonymous):

y′+k9e^(−5t)=0 ??

OpenStudy (turingtest):

what is y' ?

OpenStudy (anonymous):

dy/dt right?

OpenStudy (turingtest):

yes, and what is that for the given y ?

OpenStudy (anonymous):

-45e^(−5t) ?

OpenStudy (turingtest):

yes, plug that into the equation as well and solve for k

OpenStudy (anonymous):

45/9 thank you

OpenStudy (turingtest):

welcome
