B-meg company wants to mix exactly 700 pounds of special kind of dog food. there are two principal ingredients in the mixture, both sources of protein p1 and p2. the first source of protein, p1 cost p50 a pound and p2 cost p80 per pound. chemical constraints dictate that the mixture contain no more than 500 pound of p1 and must contain at least 300 pounds of p2. how many pounds of each ingredient must be utilized in order to minimize the cost?

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
