Juan analyzes the amount of radioactive material remaining in a medical waste container over time. He writes the function

f (x) = 10 (0.98) to represent the amount of radioactive material that will remain after x hours in the container.

Rounded to the nearest tenth, how much radioactive material will remain after 10 hours?

O 0.8 units

O 1.3 units

O 8.2 units

O 9.8 units

Correct option: Third one - > 8.2 units

Step-by-step explanation:

Assuming that the function that models the amount of radioactive material remaining after x hours is:

f (x) = 10 * (0.98) ^x

To find the amount of material after 10 hours, we just need to use x = 10 in the equation and find the value of f (x):

f (10) = 10 * (0.98) ^10

f (10) = 8.1707

Rounding to nearest tenth, we have f (10) = 8.2

Correct option: Third one
