Answer:
y = (-1/8)x^2
Step-by-step explanation:
Start with y = x^2. When the original parabola has been reflected across the x-axis, the pertinent equation becomes y = -x^2.
Now if this is scaled vertically by a factor of 1/8, we get:
y = (-1/8)x^2

Answer:SPssp=631.68
Step-by-step explanation:
Answer:
Red Line: y=4
Blue Line: y=-2
Green Line: x=-1
Yellow Line: x=6
Step-by-step explanation:
Red line: the line crosses through 4 on the y axis. Therefore, y=4.
Blue line: the line crosses through -2 on the y axis. Therefore, y=-2.
Green line: the line crosses through -1 on the x axis. Therefore, x=-1.
Yellow line: the line crosses through 6 on the x axis. Therefore, x=6.
This is a bit confusing because when you see a horizontal line your mind might assume it would be an x=. Yet, it is the opposite. Hope this helps!
Density = m/v
3.86kg=3860g
d= 3860/200
= 19.3g/cm^3
therefore it is gold.
