A sample of a radioactive isotope had an initial mass of 360 mg in the year 1998 and decays exponentially over time. A measurement in the year 2004 found that the sample's mass had decayed to 270 mg. What would be the expected mass of the sample in the year 2011, to the nearest whole number?

an altitude of 15,000 feet

step-by-step explanation:

his chances of getting a coin of higher value is 4/19

step-by-step explanation:

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus
