12¹⁶⁻⁴
<h2>12¹²</h2>
Answer:
1) 
2) 
3) 
4) 
5) 
Step-by-step explanation:
According to the information given in the exercise, the value of "x" is:

Then:
1) You must substitute
into the expresion
:

Now, you must evaluate:

2) You have to substitute the given value of "x" into the second expression:

Finally, evaluating, you get the following result:

3) According to the Zero exponent Rule, any non-zero number with an exponent of zero is equal to 1.
Then, substituting
into the expression
and then evaluating, you get:

4) By definition:

Then, substituting
into
and evaluating, you get:

5) Since:

When you substitute the given value of "x" into the last expression and then you evaluate, you get:

I think its the second one but just a fyi the site your on is ready and it looks like your doing the major test, not every answer on it are you suppose to get right its a test to see what you know and what you need to know
Answer:
Step-by-step explanation:
In the original question as shown in the attached picture, there is a compound interest table.
According to the table, Amount of $1.00 at 5.5% Compounded Daily after 40 days is $1.00604.
Using the formula: Amount = Original Principal x Amount of $1.00,
the amount in account after 40 days = $580 x 1.00604
= $583.5032
= $583.50 rounded to the nearest cent
It would be 9 ft. using the knowledge of

times the diameter (

equals aprox. 3.14) equal the circumference of a circle, and since we know the circumference, we need to divide that by

to get the diameter.
equation: 28/3.14=8.913
rounding that would bring it to 9 ft.
