How much of a 40 g sample would be left after 90 years
Since the series has a common ratio then it is a geometric series.
thus it will follow the explicit formula given by:
an=ar^(n-1)
plugging in the values we get:
an=14(1.03)^(n-1)
thus the 12th term will be:
a12=14(1.03)^(12-1)
a12=19.38
I believe it is either A or B. sorry if this is no help
Draw number line from -5 to 10. .number that line.
Then show a point in 9 and -4
I hope that's what you mean from question
