Achemist has two large containers of sulfuric acid solution, with different concentrations of acid in each container. blending 305 ml of the first solution and 580 ml of the second gives a mixture that is 10.24% acid, whereas blending 85 ml of the first mixed with 490ml of the second gives a 6.10% acid mixture. what are the concentrations of sulfuric acid in the original containers?

The rate of decay of a radioactive substance depends upon the amount present initially. the mass y (mg) of the radioactive substance cobalt-60 present in a sample at time t (years) is represented by the exponential equation y=50e −0.1315 t . answer the following questions in complete sentences. 1. how does the exponential equation above compare to the equation for simple interest that is compounded continuously? explain the similarities. 2. what is the initial amount of cobalt-60 in the sample? 2. how much cobalt-60 is left after 8.4 years? show your work. 3. what would be the y-intercept of the graph? what does it represent? 4. after how many years will the amount of cobalt-60 left be 6.25 mg? explain what happens to the cobalt-60 after 50 years? 5. discuss some “real-world” examples and uses of cobalt-60
