It would Lie at The Negative One-Point Horizontally on a Graph.
Step-by-step explanation:
? I'm not Exactly Sure
Answer: ∠ACB ≅ ∠E'C'D'; translate point D' to point B
Step-by-step explanation:
That is just my best guess.
<span>Since the major axis is 80 yards long, the distance from the center to a vertex on the major axis, which is the "a" in the equation, would be 40 yards. With similar logic we can find that the distance from the center to a vertex on the minor axis, "b" in the equation, would be 36 yards.
</span><span>With the center, a and b we are just about ready to write the equation. The standard forms for equations of ellipses are:
(x-h)^2 / a^2 + (y-k)^2 / b^2 = 1 for ellipses with horizontal major axes and
</span>x-h)^2 / b^2 + (y-k)^2 / a^2 = 1 for ellipses with vertical major axes
<span>Since the major axis is the x-axis, which is horizontal, we will use the first form. Using the values we found for a and b and the x-coordinate of the center as "h" and the y-coordinate of the center as "k" we get:
(x-0)^2 / (40)^2 + (y-0)^2 / (36)^2 = 1
which simplifies to:
x^2 / 1600 + y^2 / 1296 = 1</span>
Answer:

Step-by-step explanation:
From triangle ADB,
From triangle ADC,
The perimeter is the distance around the figure.
The perimeter
Answer:
Choice A, C and E
Step-by-step explanation:
<em>Your table is poorly presented</em>
Given
x y
First, we calculate the constant of proportionality (k)
For (3,1.47)
For (5,2.45)
For (9,4.41)
From the above calculations, the constant of proportionality is 0.49.
So, the usable rows must also have 0.49 as their constant of proportionality
