Question

Juan analyzes the amount of radioactive material remaining in a medical waste container over time. He writes the function f(x) = 10(0.98)x 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?

Answer 1

I believe this is right

Answer 2

Answer: 8.2

Explanation:

Given: Juan analyzes the amount of radioactive material remaining in a medical waste container over time. He writes the function
`f(x) = 10(0.98)^x` to represent the amount of radioactive material that will remain after x hours in the container.

Then , the amount of radioactive material will remain after 10 hours is given by :-

`f(10)=10(0.98)^(10)$$8.17072806888=8.17072806888\approx8.2`

Hence, the amount of radioactive material will remain after 10 hours =8.2 (units)
