Answer: 9 1/3 - 2/3 = 8 2/3 .
___________________________________
Note: If the answer were "8 1/3" ;
then: "8 1/3 + 2/3 =? 9 1/3 ? "
→ "8 1/3 + 2/3 = 8 3/3 = 8 + 1 = 9 = only "9" ;
____________________________________________
So the answer has to be MORE than "8 1/3"
Try "8 2/3" → "8 2/3 + 2/3 =? 9 1/3?" ?? ;
→ "8 2/3 + 2/3 = 8 4/3 = 8 + 1 1/3 = 9 1/3 " → Yes!
_________________________________________________
So, the answer is: "8 2/3" .

Another method:
_________________
Given the problem: "<span>9 1/3 - 2/3 " ;
___________________________________
Note that: "2/3 = 1/3 + 1/3"
__________________________________
So, "</span><span>9 1/3 - 2/3 = 9 1/3 - (1/3 + 1/3) = 9 1/3 - 1/3 - 1/3 = ?
________________________________________________
Start with: "</span>9 1/3 - 2/3" = 9. Then 9 - 1/3 = 8 3/3 - 1/3 = 8 2/3.
<span>______________________________________________________
</span>Another method:
____________________________
Given the problem:
____________________________
"9 1/3 - 2/3 = ?? " ;
____________________________
Convert "9 1/3" into "28/3" ; ("3*9 = 27"); ("27+1=28");
(The "3" comes from the "3" in the: "1/3" portion.)
_________________________________________________________
So, we rewrite as:
_____________________________________
28/3 - 2/3 = (28 - 2) / 3 = 26/3 ; or, 8 2/3 .

Answer:
Step-by-step explanation:
we know that
The formula to calculate continuously compounded interest is equal to
where
A is the Final Investment Value
P is the Principal amount of money to be invested
r is the rate of interest in decimal
t is Number of Time Periods
e is the mathematical constant number
we have
substitute the values in the formula
Step-by-step answer:
A vertical line test checks for single or multiple intersections with a given relations If there is a maximum of one intersection with the relation at ANY point in the domain of the relation, we can conclude that the relation is a function. If there are multiple intersections of a VERTICAL line with the function, it is not a function.
Here, we see that vertical line test on the relation shown does not produce more than one intersection at any point in the domain of the relation, hence we conclude that the graph shows a function.
An inverse of a function is a reflection of the function about the y=x line. The result is the same as the interchange of the x and y-axes.
Hence a horizontal line test on the inverse of a function gives the same results as a vertical line test of the function itself, and the conclusion is identical to the test given above in paragraph two.
