The radius of a cone-shaped tank is 4 feet less than its height. if the height of the tank is (x - 3) feet, the expression below shows the volume of the tank.
1 over 3_ (x - 7)2 (x - 3)
what does the factor 1 over 3(x - 7) represent?
the total surface area of the tank
one third of the radius of the tank
one third of the height of the tank

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
