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:

8.2 units of radioactive material will remain after 10 hours

Step-by-step explanation:

Given : f(x)=10(0.98)^{x}

To Find : , how much radioactive material will remain after 10 hours?

Solution :

Since we are given a function that represents the amount of radioactive material remaining in a medical waste container over time.

f(x)=10(0.98)^{x}

Where x denoted hours

Since we are asked to find the amount of radioactive after 10 hours .

So, put x = 10 in the given function

f(10)=10(0.98)^{10}

f(10)=10*0.8170

f(10)=8.170

Thus f(10)=8.17 ≈ 8.2

Hence 8.2 units of radioactive material will remain after 10 hours

For radioactive decay, the amount should decrease over time. Given the function:
f(x)=10(0.98)^x
We substitute the time of x = 10 hours:
f(10)=10(0.98)^{10} \\ f(10) = 8.17
Therefore 8.2 units will remain after 10 hours.

Which expression shows how 6 • 45 can be rewritten using the distributive property?
tatuchka [14]
6*45=270 is the first step you should do to get the answer you are looking for. The next thing I would do is go to all the answers to see which one comes out the same way. The first one comes to be 246, the next one is 54, the next is 270 and the last one is 220. 6*40+6*5 is the correct answer.
