Answer:
--- quadratic function
--- linear function
--- square root function
Step-by-step explanation:
Given
The attached graph
Required
The domain of each function
Starting from the left; the first function is the quadratic function.
The curve of the quadratic function stops at -2 So, the domain is:
The straight line that starts at -2 and ends at 6 is a linear function.
So, the domain is:
Lastly, the square root function begins at 6. So, the domain is:
Answer:
The answer is B.
Step-by-step explanation:
It is saying that 647.5 calories is the total amount and 320 is a part of it. so when you do 647.5-320, it becomes 327.5 and that is c. You can only do this with the equation that letter B is saying.
Answer:
1st option
Step-by-step explanation:
turn 15% into a decimal:
%15 -> 0.15
multiply $7 by 0.15 then add together:
7 x 0.15 = 1.05
$7 + $1.05 = $8.05
20 hours x $8.05 hour = $161
$161 x 10 weeks = $1610 total by the end of summer
<em>the question does not say how many hours she works normally so the answer might be off...</em>
if she continued with $7, assuming she works 20 hours/week:
20 hours x $7 = $140
$140 x 10 weeks = $1400
$1400 + $200 = $1600 total by the end of summer
Answer:
Option A. half the distance between point A and point K
Step-by-step explanation:
Ax=Fx
Fy=Ky
The distance between point A and point K is:
AK=Ax+Fx+Fy+Ky
Like Ax=Fx and Fy=Ky
AK=Fx+Fx+Fy+Fy
AK=2Fx+2Fy
Common factor 2:
AK=2(Fx+Fy)
The distance between point P and point Q is:
PQ=Fx+Fy
Then the distance between point P and point Q is half the distance between point A and point K:
PQ=Fx+Fy=AK/2=2(Fx+Fy)/2=Fx+Fy
