The amount of a sample remaining after t days is given by the equation , where A is the initial amount of the sample and h is the half-life, in days, of the substance. A scientist has a 10-mg sample of a radioactive isotope. The isotope has a half-life of 8 days. After 16 days, how much of the radioactive isotope remains? 1.2.0 mg2.2.5 mg 3.5.7 mg 4.7.1 mg

2.5 mg

Step-by-step explanation:

We are given that

A=Initial amount=10 mg

Half life,h=8 days

We have to find the mass of radioactive isotope remains after 16 days.

t=16 days

We know that the amount of radioactive isotope after t days is given by

Using the formula

i would pic false cause it goes down towards negative

step-by-step explanation:

well we know there are 4 clubs in 52 cards so it’s replaced so it should be 3/51
