A sample of a radioactive isotope had an initial mass of 620 mg in the year 2003 and decays exponentially over time. A
measurement in the year 2005 found that the sample's mass
had decayed to 390 mg. What would be the expected mass of
the sample in the year 2010, to the nearest whole number?

y = x + 95

y = 42 + 95

y=137 mm hg

incomplete question. how do you expect anyone to you when you do not post the question in its entirety?

a

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|
