Answer:
There is 25 1/8 inches left
Step-by-step explanation:
We have a board that is 38 3/4 inches
We cut away 13 1/4
38 3/4
-13 1/4
-----------
25 2/4
The saw takes 3/8
25 2/4
- 3/8
-------------
Get a common denominator of 8 2/4 * 2/2 = 4/8
25 4/8
- 3/8
-------------
25 1/8
There is 25 1/8 inches left
1. You have the function 
2. You know that
with
, because the division by zero is not defined. So ,
for
where
is a integer number.
3. Then, to find the domain of the function given in the problem, you must make 
Where
is odd number.
4. Therefore:

5. Finally, the domain is: 
The answer is: 
Answer:

Step-by-step explanation:

12p+7>139 Start
12p>132 Subtract 7
p>11 Divide 12
The complete question in the attached figure
we know that
sin40° = opposite side / hypotenuse
opposite side =AC
hypotenuse = AB-------> 10 in
so
sin 40=AC/AB---------> AC=AB*sin 40-------> AC=10*sin 40
the answer is
AC=10*sin 40
