Answer:

                         S(t)=450\times(1/3)^t

Explanation:

The element is <em>einstenium-253</em>. That means that the mass number, i.e. numbrer of protons plus neutrons, of this isotope is 253, but that is not relevant to answer the question.

It is said that the element <em>loses about 2/3 of its mass every month, </em>then to find the remaining amount, every month you have to multiply by 1/3.

With that you can create a decaying function that gives a sample's mass in grams:

         

        Initial\text{ }mass=M_0\\ \\ Mass\text{ }after\text{ }1\text{ }month=M_0\times1/3\\ \\  Mass\text{ }after\text{ }2\text{ }months=M_0\times(1/3)^2\\ \\  Mass\text{ }after\text{ }3\text{ }months=M_0\times(1/3)^3\\ \\  Mass\text{ }after\text{ }t\text{ }months=M_0\times(1/3)^t

Now you can replace the initial mass with 450 g and write the specific function for this sample:

          S(t)=450\times(1/3)^t

Write an equation parallel to x - 3y = 9 that passes through the point ( 3, -1 )
ivolga24 [154]

Answer:

Step-by-step explanation:

Use the point-slope formula.

y - y_1 = m(x - x_1)   ....   x_1 = 3 and y_1 = - 1

m is the slope to  x - 3y = 9 because (lines are  parallel )

calculate : m   by equation   x - 3y = 9 :

x = 3y +9

divid by : 3      1/3 x = y + 3

y =  (1/3) x - 3      so : m = 1/3

an equation parallel to x - 3y = 9 that passes through the point ( 3, -1 ) is :

y +1 = (1/3)(x - 3)
