Abby's class is taking a field trip to the Bunker Hill Monument. Abby read that to reach the top of the monument she must climb 294 steps, each of which is 8 inches tall. Abby weighs 130 pounds. How many foot-pounds of work will she have to perform to climb to the top of the monument?

the correct answer is c

a natural event such as a flood, earthquake, or hurricane that causes great damage or loss of life.

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

the answer to this would be 5x^3-6x^2-24 over 3x^2

hope this if needed hmu
