Question 47851This question is from textbook College Algebra
: A radioactive substance decays in such a way that the amount of mass remaining after t days is given by the function
m(t)= 13e^(-0.015t) where m(t) is measured in kilograms.
a. Find the mass at time t = 0.
m(0) = 13e^(-0.015)(0) = 13 kilograms
b. How much of the mass remains after 45 days?
m(45) = 13e^(-0.015)(45)
= 13(0.509)
= 6.619 kilograms remaining.
Hope this is close,
Thank you very much!! This question is from textbook College Algebra
