Question

The half-life of an element in the periodic table measured over a period of time, t, is modeled by the function f(t)=16(1) What is the initial amount of the element?A-12OB.8OC.16OD.OReset Selection

Answer 1

Answer: C. 16

Step-by-step explanation

We are given the function model:

`f(t)=16((1)/(2))^t`

To know the initial amount of element, this means that t = 0:

`f(0)=16((1)/(2))^0`

And as something elevated to 0 equals 1, then:

`f(0)=16\cdot1=16`
