Answer:
D. (y +4)² = -4(x -2)
Step-by-step explanation:
The directrix is a vertical line, and the focus is to the left of it. The parabola will open to the left.
The vertex is halfway between the focus and directrix, so is located on the same horizontal line as the focus, at ...
x = (1 +3)/2 = 2
The focus to vertex distance is the difference in x-coordinates: 1 -2 = -1. This is the value of p in the form ...
(y -k)² = 4p(x -h) . . . . . . . parabola with vertex (h, k)
The equation is ...
(y +4)² = -4(x -2)
_____
<em>Additional comment</em>
Once you determine that the directrix is a vertical line, you know the equation will have a y² term. The only answer choice that has that is D.
If the 7 centimeters is converted into 35 meters. Then the scale factor of the drawing is 0.2 centimeters per meter.
<h3>What is
the scale factor?</h3>
The scale factor means the changing of the size of the object without changing the shape. The size of the object may be increased or decreased based on the scale factor.
Diego made a scale drawing of a community college.
A building at the college, which is 35 meters wide in real life, is 7 centimeters wide in the drawing.
Then the scale factor will be given as
![\begin{aligned} 35 \rm \ m &= 7\rm \ cm\\\\1 \ \rm m &= \dfrac{7}{35} \rm \ cm\\\\1 \rm \ m &= 0.2 \rm cm \end{aligned}](https://tex.z-dn.net/?f=%5Cbegin%7Baligned%7D%2035%20%5Crm%20%5C%20m%20%26%3D%207%5Crm%20%20%5C%20cm%5C%5C%5C%5C1%20%20%5C%20%5Crm%20%20m%20%26%3D%20%5Cdfrac%7B7%7D%7B35%7D%20%5Crm%20%20%5C%20cm%5C%5C%5C%5C1%20%20%5Crm%20%5C%20m%20%26%3D%200.2%20%5Crm%20%20cm%20%5Cend%7Baligned%7D)
