Answer:

10 months

Step-by-step explanation:

22x+80=30x

subtract both sides by 30x

-8x+80=0

then subtract 80 from both sides

−8x=−80

divide both sides by -8

x=10

Consider xưy" – 14xy' + 56y = 0. Find all values of r such that y=x" satisfies the differential equation for x > 0. Enter as
beks73 [17]

I bet the ODE is supposed to read

x^2y''-14xy'+56y=0

Then if y=x^r, we have y'=rx^{r-1} and y''=r(r-1)x^{r-2}, and substituting these into the ODE gives

r(r-1)x^r-14rx^r+56x^r=0\implies r(r-1)-14r+56=r^2-15r+56=0

Solving for <em>r</em>, we find

r^2-15r+56=(r-8)(r-7)=0\implies \boxed{r=8\text{ or }r=7}

so that y_1=x^8 and y_2=x^7 are two fundamental solutions to the ODE. Thus the general solution is

\boxed{y(x)=C_1x^8+C_2x^7}

Given that y(1)=4 and y'(1)=3, we get

\begin{cases}4=C_1+C_2\\3=8C_1+7C_2\end{cases}\implies C_1=-25\text{ and }C_2=29

So the particular solution is

\boxed{y(x)=29x^7-25x^8}
