Select the equation that is the inverse of the given function.
f(x) = * = 3
.
f-1(x) = 5x + 15
f-1(x) = 5x + 3
f-1(x) = 3x - 5
-1(x) = x
done

the answer is two. hope this !

10 down (bang1)

5 up

5down (2)

2.5 up

2.5 down (3)

1.25 up

1.25 down (4)

now add them up : )

hoped i lol

i believe the answers 600m

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
