Answer:
C. 
Step-by-step explanation:
From the graph of the function, we can see that the domain of the function is 
the range of the function is 
Consider the parent function 
The domain of this function is 
the range of this function is 
The function has
the domain
and the range
All other options have different domain, or the range, or both the domain and the range.
Answer:
$1,392
Step-by-step explanation:
1,200(0.08)(2) = 192
1,200 + 192 = $1,392
The mean increases. When Deleware (2,000: 2) is included the mean must be divided by 9 instead of 8.
Answer:
1. 30°
2.90°
3. 12 units
Step-by-step explanation:
I can't believe there's nothing confirming that this is a parallelogram/a rhombus?! Assuming is awful, and I wish you could say you can't know for sure lol but for the sake of this answer, let's just call it a rhombus. (There was probably some context elsewhere that you didn't put over here, hopefully.)
1.
The reason I say this is: in a rhombus, the diagonals bisect the angles. This means that the diagonals split the angles they meet into two equal parts. That way, it would make sense. m∠QPR=m∠SPR=30°.
2.
If it is a rhombus, the diagonals are perpendicular to each other, so m∠QTP should be 90°.
3.
Diagnonals in a rhombus (and in any parallelogram) bisect each other, so PT=TR=6, and RP=PT+TR=12 units.
Sorry if this is all dreadfully wrong, and I hope I helped you!
A. 250+0.08s=410
-250. -250
0.08s= 160
0.08s/0.08s 160/0.08s
S=2000
