Answer:
A. Yes, because by 2206, the radioactive element remaining in the area is less than 800 Bqs.
Step-by-step explanation:
Function for the amount of radioactivity:
The function for the amount of radioactivity, in t years after 1996, is given by:
Find f(220) to determine the amount of becqurels in 2206.
121.42 < 600, so the area will be safe, and the correct answer is given by option A.
70 / 50 = 1.4
1.4 * 1.4 = 1.96
So, the stopping distance increases by a factor of 1.96
170 feet * 1.96 = 333.20 feet
