Answer:
C. 20
Step-by-step explanation:
Take a value from the x-axis (Width) and the y-axis (Height) and substitute them into the equation. I'll use the point (5, 4).
Height = Constant/Width
4 = Constant/5 (Given)
20 = Constant (Multiplied 5 on both sides)
Where's the so-called "parabola tool?"
The vertex is relatively easy to find. Find the midpoint of the segment of the x-axis connecting x=2 and x=6; it is x=4. Then evaluate the function at x=4:
f(4) = (4-2)(4-6) = 2(-2) = -4. The vertex is at (4,-4).
Plot (4,-4). Then (arbitrarily) let x=0 and find y: f(0) = y = (-2)(-6) = -12.
So, when x = 0, y = -12.
Plot this point (1, -12). realize that the parabola is symmetric about the line x=4. (1,-12) is 3 units to the left of the axis of symm, and thus another point on the parab. is 3 units to the right of this axis, x= 7. Plot (7,-12). Now draw the parabola thru (7,-12), (1, -12) and (4, -4). The parab. opens up.
Answer:
r = 10.68 in
Step-by-step explanation:
V = Pi x r^2 x h
228 pi = pi x r^2 x 2
(228 pi)/(pi x 2) = r^2
228/2 = r^2
Sqrt 114 = r
r = 10.68 in
Answer:
<em><u>(-2,1) or Option 4</u></em>
Step-by-step explanation:
So the way I did it is you look at the row x first then y. So when looking at row x you see that point A is located at -2. Then when you are looking at column y you see that point A is at 1.
<em><u>So (-2,1) is your answer.</u></em>
Hope this helps ;)
