9. Given the graph, state the domain and range of the function using interval notation.
Domain: [5, -2] U (1,3)
Range: (-4,4]
Domain:(-5,-2) U (1,3]
Range: (-4,4)
Domain: (-4,4)
Range: (-5,-2) U (1,3]
Domain: (-5,3]
Range: (-4,4)

8+10

step-by-step explanation:

you multiply 4 by 2 and 5 by 2

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
