The given net pay is not correct because the medicare is not 1.45% of her gross pay. The medicare should be $11.02, making the correct net pay $641.86
Step-by-step explanation:
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

Geometric figure is: line.
