Answer:

x =5

Step-by-step explanation:

We can use ratios for the side lengths

9 x

--------- = -----------

9+18 x+10

Using cross products

9 (x+10) = x * (9+18)

Distribute

9x+90 = x*27

9x+90 = 27x

Subtract 9x from each side

9x-9x+90 = 27x-9x

90 = 18x

Divide each side by 18

90/18 = 18x/18

5 =x

Find a such that the solution of y'' + y' − 2y = 0, y(0) = a, y' (0) = 1 tends to zero as t → +∞.

Kay [80]

Answer:

Step-by-step explanation:

$y'' + y' − 2y = 0, y(0) = a, y' (0) = 1$

Auxialary equation is

$m^2+m-2=0\\m=-2,1$

General solution is

$y=Ae^{-2x} +Be^x$

$y(0) = A+B =a$

$y'(0) = -2Ae^{2x} +Be^x = -2A+B = 1$

Eliminate B to get

3A =a-1

We know that y tends to 0 when x tends to infinity for any finite A

i.e. a should be a finite real number.
