If g(x, y) = x2 + y2 − 6x, find the gradient vector ∇g(2, 4) and use it to find the tangent line to the level curve g(x, y) = 8 at the point (2, 4). gradient vector correct: your answer is correct. tangent line equation correct: your answer is correct. sketch the level curve, the tangent line, and the gradient vector.

nswer: a   y-axis

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
