Answer:
Domain: (-3, 7)
General Formulas and Concepts:
<u>Algebra I</u>
- Domain is the set of x-values that can be inputted into function f(x)
- Interval Notation - [a, b] is inclusive, (a, b) is exclusive
Step-by-step explanation:
According to the graph, our x-values span from -3 to 7. Since both are open dot, they are exclusive from the domain:
Interval Notation (-3, 7)
Inequality Notation -3 < x < 7
The measure of ∠ACB will be 110°
<u><em>Explanation</em></u>
According to the diagram below, 
and 
are the perpendicular bisectors of 
and 
respectively and they intersect side 
at points 
and 
respectively.
So, 
and 
Now, <u>according to the 
postulate</u>, ΔAPE and ΔCPE are congruent each other. Also, ΔCFQ and ΔBFQ are congruent to each other.
That means, ∠PCE = ∠PAE and ∠FCQ = ∠FBQ
As ∠CPQ = 78° , so ∠PCE + ∠PAE = 78° or, ∠PCE = 
° and as ∠CQP = 62° , so ∠FCQ + ∠FBQ = 62° or, ∠FCQ = 
°
Now, in triangle CPQ, ∠PCQ = 180°-(78° + 62°) = 180° - 140° = 40°
Thus, ∠ACB = ∠PCE + ∠PCQ + ∠FCQ = 39° + 40° + 31° = 110°
Where’s the photo? But I need to answer with a photo 3.8 ft and 1.1 ft equals 4.9 ft
Q1:-
-------
12*12= 144
11*11=121
so the answer of 1. lies between 11 and 12
Q2:-
--------
9*9=81
10*10=100
so sqrt(82) is between 9 and 10
Supplementary angles equal to 180
So, adjacent angle + exterior angle = 180
adjacent angle = 180 - 155 = 25
Now, non-adjacent + adjacent = 90
non-adjacent = 90 - 25 = 65
So 65 degrees is your answer.
