After the release of radioactive material into the atmosphere from a nuclear power plant in a country in 1992, the hay in that country was contaminated by a radioactive isotope (half-life 7 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?
The

days for it to be safe to feed the hay to the cows.
The farmers needed to wait approximately
(Round to one decimal place as needed.)

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i
