A farmer filled two cylindrical silos with wheat . The wheat in both silos has a density of 50 pounds per cubic foot . He had the wheat tested for protein content . The larger silo has a radius of 5 feet , a height of 10 feet , and the wheat is 12 % protein . The smaller silo has a radius of 6 feet , a height of 6 feet , and the wheat is 15 % protein . The farmer states that the wheat in each silo contains over 5000 pounds of protein . Which of these is a correct evaluation of the farmer's statement ?

If f(x) = 3-2x and g(x) =1/x+5 to what is the value (f/g)(8)

With these: 18/36 = 1/? missing number change 1 5/8 to improper fraction. change 19/5 to a mixed number.

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
