Solve the differential equation (x^2+3)y" - try' + 16y = 0, y(0) = -1, 7(0) = 3 by means of a power series about = 0. (a) find the recurrence relation, and also (b) find the first four nonzero terms in each of two linearly independent solutions.

57.09 minus 7.0435 equals

step-by-step explanation:

just subtrach them both and u get the answer of 50.0465

just go here

its what i use

step-by-step explanation:

ending amount = beginning amount / (2^n)

where "n" = number of half-lives (or elapsed time / half-life)

ending amount = 50 mg / (2 ^10 / 5.3)

ending amount = 50 mg / (2 ^ 1.8867924528)

ending amount = 50 m / 3.6981210597

ending amount = 13.5203794557 mg

or about 13.5 mg remain
