After the release of radioactive material into the atmosphere from a nuclear power plant in a country in 1988, the hay in that country was contaminated by a radioactive isotope (half-life 5 days). If it is safe to feed the hay to cows when 12%of the radioactive isotope remains how long did the farmers need to wait to use this hay?

it would more likely be bald eagle because its has more in the box so about 75%.

step-by-step explanation:

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
