If you add the digits and it divides by 9 then it divides for that number

Like 765 is 7+6+5=18 since 18/9=2 then 765 divides by 9

Find the solution of the given initial value problem. ty' + 6y = t2 − t + 1, y(1) = 1 6 , t > 0

gtnhenbr [62]

Answer:

Step-by-step explanation:

Given is a differential equation as

$ty' + 6y = t^2 - t + 1, y(1) = 1 6 , t > 0$

Divide this by t to get in linear form

$y'+6y/t = t-1+1/t$

This is of the form

y' +p(t) y = Q(t)

where p(t) = 1/t $e^(\int 1/tdt) = t$

So solution would be

$yt = \int t^2-t+1 dt\\= t^3/3-t^2/2+t+C$

siubstitute y(1) = 16

$16 = 16^3/3-128+1+C\\C = -1206$

The polygons are similar. Find the missing side length. NO LINKS!!!!

timurjin [86]

Answer:

CD = 27

Step-by-step explanation:

Given the triangles are similar then the ratios of corresponding sided are equal, that is

$\frac{CD}{KD}$ = $\frac{CB}{KL}$ , substitute values

$\frac{CD}{9}$ = $\frac{30}{10}$ = 3 ( multiply both sides by 9 )

CD = 27
