My question got deleted so I'll post these into two separate posts 100 POINTS!

Convert 1 million seconds to years. (Round to 3 decimal places.)

If your teacher is 50 years old, what is their age in seconds?

Convert 46 inches to miles (there are 12 inches in one foot). Round 6 decimal places.

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

Wich statement could be used to explain why the function h(x)= x^3 has an inverse relation that is also a function

10 points? me . its important ‼️‼️
