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

Respuesta :

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

Step-by-step explanation:

hope this helps!
