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  

Step-by-step 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)
