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?

since x  is the number of hours and they give you 10 hours replace 10 for x

 so it becomes 10 x (0.98) x 10 = 98

answer: d. $20

step-by-step explanation:

just took the test

x is greater than 5

step-by-step explanation:

2x+7 is greater than 17

    -7                           -7

2x is greater than 10

divide by 2 each side

x is greater than 5
