Research Assignment: Modeling Radioactive Decay

Research a radioactive material used within your community (city, state, or country) whose decay can be modeled using a differential equation.
State the equation for your model and cite the reference.
Graph the equation for the model. The graph does not have to be to scale.
Make a prediction using the model.
Find the limit of your model. How long will it take for the material to become “safe”? “Safe” means that the radiation coming from the material is no longer a danger to public health.

where's the diagram?

step-by-step explanation:

answer: integers are just whole numbers: positive, negative, and zero.

i = {-∞, -2, -1, 0, 1, 2, 3, ∞}

let x = 1st integer

let y = 2nd integer

x = 3y + 17   {equation 1}

xy = -24         {equation 2}

substitute 3y+17 in place of x n equation 2

and solve for y.

(3y+17)y = -24

3y2 + 17y = -24

3y2 + 17y + 24 = 0

from quadratic equation:

y = [-17±√(172-4(3)(24))]/(2(3))

y = (-17 ±√1)/6

y = (-17+1)/6   or     y = (-17-1)/6

y = -16/6           or     y = -18/6

y = -2 2/3         or   y = -3

since we are dealing with

y = -3

x = 3y+17 = -9+17 = 8

the integers are -3, 8

step-by-step explanation:

54.667> 54.666

17.889< 17.899

these are both true
