1 Which description below best describes the motion that could be occuring at section B on the graph above?

The bicycle rider is returning home.

The bicycle rider is stopped because he got a flat tire.

The bicycle rider is speeding up because he is traveling uphill.

The bicycle rider has slowed down because he is traveling uphill.

thus, the first answer choice, y = sec x, is the correct one

answer:

probably the same as it is today since you did not eat the corn dogs yet

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
