Answer:
c) 1 2 4 8
Step-by-step explanation:
<u>Explanation </u>:-
<u><em>Geometric sequence</em></u>
The sequence is of the form a , a r , a r² , a r³ ,.......
'a' is the first term
'r' is the common ratio
1 , 1(2) , 1( 2)² , 1( 2 )³ ...... is a geometric sequence
here a = 1
common ratio
<em>The sequence 1 2 4 8 is a geometric sequence</em>
Mass of an element = 310 grams
Percentage of the element that will decay in a minute = 5.7%
Quantity of the element that will decay in one minute :
Thus, 17.67 grams of the element will decay every minute.
Quantity of element that will decay after nine minutes :
Thus, 159.03 grams of the element will decay after 9 minutes.
Quantity of element that will remain after 9 minutes :
Thus, 150.97 grams of the element will remain after nine minutes.
We can round off 150.97 to 151.00.
Therefore, <u>151.00 grams</u> of the element will remain after 9 minutes.
