Question

A radioactive compound with mass 470 grams decays at a rate of 3% per hour. Which
equation represents how many grams of the compound will remain after 6 hours?Submit Answer

Answer 1

The standard exponential function is expressed as:

$C=A(1-r)^t$

Where:

A = 470

r = 3% = 0.03

t = 6 hours

So, substitute the values in the formula:

$C=470(1-0.03)^6$

Answer:

$C=470(1-0.03)^{6}$
