Guess the song, 100 POINTS One, two, three, four
Need a boy who can cuddle with me all night
Keep me warm, love me long, be my sunlight
Tell me lies, we can argue, we can fight
Yeah, we did it before, but we'll do it tonight
An afro, black boy with the gold teeth
With dark skin, looking at me like he know me
I wonder if he got the G or the B
Let me find out and see, coming over to me, yeah
These days, I'm way too lonely
I'm missing out, I know

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
