the graph models the decay of a sample of iodine - 125, where x is the time that has passed and y is the amount remaining in the sample in grams. what was the size of the sample at the beginning of the experiment? 12.5 grams 25 grams 50 grams 120 grams

the graph models the decay of a sample of iodine - 125, where x is the time that has passed and y is the amount remaining in the sample in grams. what was the size of the sample at the beginning of the experiment? 12.5 grams 25 grams 50 grams 120 grams

Answer

Explanation:

Step1: Identify the initial time value

At the beginning of the experiment, time ( x = 0 ).

Step2: Find the corresponding ( y )-value from the graph

The graph shows the point ((0, 50)), where ( y = 50 ) when ( x = 0 ).

Answer:

50 grams
