For the differential equation dy/dt=ky, k is a constant, y(0)=24, and y(1)=18. What is the value of k?
Gre4nikov [31]

The equation is separable, so solving it is trivial:

\dfrac{\mathrm dy}{\mathrm dt}=ky\implies\dfrac{\mathrm dy}y=k\,\mathrm dt

Integrating both sides gives

\ln|y|=kt+C\implies y=e^{kt+C}=Ce^{kt}

Given y(0)=24 and y(1)=18, we find

24=C

18=Ce^k=24e^k\implies e^k=\dfrac34\implies k=ln\dfrac34

so the answer is E.

It seems like you have the answer already. but heres how its calculated.
\frac{100}{15} = \frac{?}{3} 
so the missing number is 20 **cross multiply 100 and 3 to get 300 then divide 15 into 300 to get 20**

\frac{160}{100} =  \frac{80}{?} 
so the missing number is 50
 **cross multiply 100 and 80 to get 8000 then divide 160<span> into 8000 to get 50**</span>
