If h(x) = x - 7 and g(x) = x2, which expression is equivalent to (907)(5)?
O (5-7)?
(5) 2-7
(5)?(5 – 7)
(5 – 7)x2

3+3+3+2*2*2+29*12 = 365

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
