One of the byproducts of nuclear power generation is uranium-233. uranium is decaying at a constant 57% rate per day. if 3,820 pounds are produced from a power plant, what will the amount be in 15 days?

Given that the rate of Uranium decay is 57%, this means that after each day, only 0.43 of the mass from the prior day is left. The equation that would best represent the scenario is,
                                    a(t) = a₁(0.43^t)
where a(t) is the mass after t days and t is the number of days. Substituting,
                                    a(t) = 3,280(0.43^15) 
                                           = 0.01 lbs. 

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0

the value of x is equal to 0.
