Answer:

1) D

2) C

3) D

4) B

Step-by-step explanation:

Background info: Left pointing vector is less than, right pointing is greater than. A circle without the middle filled in shows that value is excluded, a full circle shows included(which would be greater than or equal to, and less than or equal to)

With that you look at the sign for each problem and apply what I wrote above.

For example for question 1, x is greater than or equal to 8 so you pick the right/positive arrow, and the filled in circle.

Hope this helps!

Answer:

$A(t)=A_{0}e^{\frac{ln(\frac{1}{2})}{22}t}$

Step-by-step explanation:

This half life exponential decay equation goes by the formula:

$A(t)=A_{0}e^{kt}$

Where

$k=\frac{ln(\frac{1}{2})}{Half-Life}$

Since half life is given as 22, we plug that into "Half-Life" in the formula for k and then plug in the formula for k into the exponential decay formula:

So,

$k=\frac{ln(\frac{1}{2})}{Half-Life}\\k=\frac{ln(\frac{1}{2})}{22}$

Now

$A(t)=A_{0}e^{\frac{ln(\frac{1}{2})}{22}t}$

third choice is correct.
