The graph of f (x) = rootindex 3 startroot x + 8 endroot is shown.

on a coordinate plane, a cube root function goes through (negative 16, negative 2), has an inflectio point at (negative 8, 0), and goes through (0, 2).

which statement is true?

the function is only increasing when x ≥ −8.
the function is only increasing when x ≥ 0.
the function is always decreasing.
the function is always increasing.

Explain step-by-step how to simplify -5(2x – 3y + 6z – 10).

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

Can someone me and do the problem plz so i can understand it more better
