Answer:
The correct option is 3. The green figure is similar to the 9 by 6 figure.
Step-by-step explanation:
Let a small square represents 1 unit.
From the given figure it is noticed that
1. The dimensions of red figure is 4 by 3.
2.The dimensions of brown figure is 4 by 6.
3.The dimensions of green figure is 2 by 3.
3.The dimensions of purple figure is 3 by 6.
The dimensions of given figure is 9 by 6. The proportion of its dimensions is
The corresponding sides of two similar figure are proportional. It means the ration of sides must be .
The dimensions of green figure is 2 by 3. It means the proportion of its dimensions is .
Therefore the correct option is 3. The green figure is similar to the 9 by 6 figure.
The given equation is
(x - 2)² = 5(y + 1).
The given equation for the parabola is in the standard form
(x - h)² = 4p(y - k)
where
h = 2
4p = 5, so that p = 5/4
k = -1
The vertex is at
(h,k) or (2, -1)
The focus is located at
(h, k + p) or (2, -1 + 5/4) = (2, 1/4)
We should place the bulb at p = 5/4 from the vertex.
