Answer:
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:
correct answer is C 8.2 units
