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

answer: all of the odd numbers were opened

the first person was the one that was opening all of the lockers. since one is odd, this causes all of the odd number lockers to be opened in the end.
