The steps below show the work of a student used to calculate the number of yards in 804.5 meters. (1 mile = 1,609 meters)
(1 mile = 1,760 yards)
1 mile
Step 1: 1,609 meters x
= 2 miles
804.5 meters
1,760 yards
Step 2: 2 miles x
= 3,520 yards
1 mile
Step 3: 3,520 yards
(1 mile = 1,609 meters)
(1 mile = 1,760 yards)

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

The clayton family’s pool has vertices at the coordinates (0, 2), (0, 5), (2, 5), (2, 6), (5, 6), (5, 1), (2, 1), and (2, 2). if each grid square has an area of 9 square feet, what is the area of the pool?
