55/2 =27.5 that is the answer and the average rate of change
Answer:
A. without changing the setting of the compass, place the point of the compass on point D and drawn out the intersects line L and extends below line L.
Step-by-step explanation:
In the figure attached, the procedure is shown.
In this case, we are at step 2, the first arc was made, and you have to make the second arc (without changing the setting of the compass) placing the point of the compass on point D.
For the answer to the question above, you can set up a proportion where
x/44=1/0.678.
<span>x = 1 </span>
<span>--- --- </span>
<span>44 0.678
</span>Then divide both sides .
<span>0.678x = 44 </span>
<span>x = 44/0.678 </span>
<span>x = $64.897
</span>So the answer is
<span>x = $64.90
</span>I hope
I helped you with my answer to your problem. Have a nice day!
Answer:
Step-by-step explanation:
2)f(x) = 2x² +4x - 3
a = 2 ; b = 4 ; c = -3
1) Put x = -1 in the equation
f(x) = 2*(-1)² + 4*(-1) -3 = 2 - 4 -3 = -5
Vertex = (-1,-5)
2) Upward
3) Minimum
4) axis of symmetry = -b/2a = -4/2*2=-4/4= -1
x = -1
5) domain: all real numbers (-∞ ,∞)
Range : y ≥ -5 ; [-5 , ∞)
3) f(x) = 3x² - 6x + 4
Vertex : (1,1)
Opening : upward
Minimum
Axis of symmetry: x = 1
Domain: all real numbers
Range: y ≥ 1 ; [1, ∞)
4)f(x) = -x² - 2x - 3
a) Vertex: f(x) = -(-1)² - 2*(-1) - 3 = -1 + 2 - 3 = -2
Vertex( -1,-2)
b) downward
c) Maximum
d) Axis of symmetry: x = 2/-2 = -1
x = -1
e) Domain: all real numbers
Range: y ≤ -2 ; (-∞ , -2]
5)f(x) = 2(x -2)²
a) Vertex: (2, 0)
b) Opening: upward
c) Minimum
d) x = 2
e)Domain: all real numbers
Range: y ≥ 0 ; [0,∞)
