3. An element has a half-life of 29 hours. If 100 mg of the element decays over a period of 58 hours,
how many mg of the element will remain?

They are both unlikely.  certain would be 100%, likely would be anywhere above 50%, and unlikely would be under 50%can i have brainliest, ?

The answer is    (d) 7/2======we have    we also  have an integral      notice how function f splits up at x = 0. there's a left piece and a right pieceso we'll need to do the same thing with our integral: split it at x = 0we use a property of integrals that allows us to split up and sum:     notice that for the piecewise function f, the function has the equationf(x) = x when x  ≤ 0. so for the integral  , f(x) = x so it changes into      for the piecewise function f, the function has the equationf(x) = x+1  when x  > 0. for the integral  , we have    therefore, back to our splitted integral:
