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.
Answer:
The expression is 300/t, , or 300 divided by t
Step-by-step explanation:
I = P x r x t
P is the principal amount, $420.00.
r is the interest rate, 3.5% per year
t is the time involved, 5 years
420 × 0.035 × 5 = 73.50
73.50 + 420 = 493.5
As the sample size is too small, the margin of error cannot be trusted.
