What is the rate of change from x = π to x = 3 pi over 2?

trig graph with points at 0, 0 and pi over 2, 3 and pi, 0 and 3 pi over 2, negative 3 and 2 pi, 0

negative pi over 6
negative 6 over pi
pi over 6
6 over pi

Answer with explanation:

Rate of change between two points , is equal to

We have to find rate of change from .

Points on the curve are, (0,0) ,

Rate of change using above formula

Option B:  Negative 6 over pi

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
