A particular radioactive isotope has a decay rate of -0.173% where time is measured in years. A scientist started with 1,490 milligrams of this material. Use the Continuous Decay Formula: F=Pert to find how much of the material will exist in 640 years?

Adeposit of 5500 at 6% for 3 years equals

Given the system of equations presented here: 2x + 4y = 14 4x + y = 20 which of the following actions creates an equivalent system such that, when combined with the other equation, one of the variables is eliminated? multiply the second equation by â’4 to get â’16x â’ 4y = â’80 multiply the second equation by â’1 to get â’4x â’ y = â’20 multiply the first equation by 2 to get 4x + 8y = 28 multiply the first equation by â’1 to get â’2x â’ 4y = â’14
