Answer:

  (b)  (1, 1/6)

Step-by-step explanation:

The "unit rate" is always the y-value for x=1 when the relationship is proportional (as it is here).

That point is not specifically shown on the graph. It would be (1, 1/6).

Thorium -228 is a radioactive substance that decays 50% every 1.9 years. How much of a 50 gram sample will exist after 22.8 year
Evgesh-ka [11]

Answer:

A=0.0122\ gr

Step-by-step explanation:

The exponential decrease formula that we must use is:

A=A_0e^ {-kt}

Where A is the amount of thorium as a function of time

A_0 is the initial amount and k is the decrease rate

We know that initially there are 50 gr and that you decay 50% every 1.9 years.

So

A=A_0*0.5=50*0.5 = 25\\\\t=1.9

25=50e^ {-k(1.9)}

We solve the equation for k

0.5=e^ {-k(1.9)}

ln(0.5)=ln(e^ {-k(1.9)})

ln(0.5)=-k(1.9)

-1.9k=ln(0.5)

k=-\frac{ln(0.5)}{1.9}\\\\k=0.3648

After 22.8 years the amount of thorium that exists is:

A=50e^ {-0.3648(22.8)}

A=0.0122\ gr
