 A = V1 - V0/t.....multiply both sides by t
At = V1 - V0....add V0 to both sides
At + V0 = V1
        
                    
             
        
        
        
Answer:
The tank must remain intact for 1183 years.
Step-by-step explanation:
Exponential equation for decay:
The amount of a substance after t years is given by:

In which A(0) is the initial amount and r is the decay rate.
A storage tank contains a liquid radioactive element with a half-life of 96 years. 
This means that  , and we use this to find r.
, and we use this to find r.







So

It will be relatively safe for the contents to leak from the tank when 0.02% of the radioactive element remains. How long must the tank remain intact for this storage procedure to be safe?
This is t for which  . So
. So







The tank must remain intact for 1183 years.

<h3>
Social security</h3>
Social security rate is 6.2% or 0.062
Weekly salary=$350
Using this formula
Social security=Social security rate×Weekly salary
Let plug in the formula
Social security=0.062×$350
Social security=$21.70
Therefore the amount withheld for Social Security weekly: $21.70.

- the rule is not one-to-one
Step-by-step explanation:
Applying the squaring rule to each of the elements of the domain, we get ...
   
__
1. There are 7 different numbers in the Domain list.
2. See above
3. There are 5 different numbers in the Range list.
4. The rule "square me" is not "one-to-one" Two different values in the domain can result in the same value in the range. -3 and 3 both result in 9. -1/2 and 0.5 both result in 1/4.
