You are standing in Top of a building that is under construction. Someone Drops a box of nails off the side of the building, and you count that it takes at least 5 seconds for the box
to hit the ground. The time
it takes something to fall from a distance d (in meters)can be found from the equation

A. using this equation, Figure out the range of possible heights the building has.

B. Later in the day you decide to try a more precise experiment. You stand at a differnt height in the building and Drops the box of nails, but this time you use a stopwatch. You measure that it took exactly 3.4 seconds for the nails to hit the ground. How high were you when you dropped the nails?

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
