1.09 that's the answer ! I just wrote extra stuff for the sake of it . x= 1.09
ANSWER: 92
EXPLANATION:
You plug in 30 where t us and solve.
3(30)+2=92
By letting

we get derivatives


a) Substitute these into the differential equation. After a lot of simplification, the equation reduces to

Examine the lowest degree term
, which gives rise to the indicial equation,

with roots at r = 0 and r = 4/5.
b) The recurrence for the coefficients
is

so that with r = 4/5, the coefficients are governed by

c) Starting with
, we find


so that the first three terms of the solution are

Answer:-1 and 0
