Question

One of the by products of nuclear power generation is uranium 233 uranium is taking out a constant 30% rate per day if 12,880 pounds are produced from power plantLooks what will the amount be in 20 days

Answer 1

For this case we have a function of the form:
 $y = A * (b) ^ x$
 Where,
 A: it is the initial amount
 b: is the growth rate
 x: it's time
 Substituting values we have:
 $y = 12880 * (1.30) ^ x$
 For 20 days we have:
 $y = 12880 * (1.30) ^ {20}  y = 2447839$
 Answer:
 the amount will be 2447839 pounds in 20 days
