The correct standard form of the equation of the parabola is:
= 4(y - 3).
<h3 /><h3>What is a parabola?</h3>
An equation of a curve that has a point on it that is equally spaced from a fixed point and a fixed line is referred to as a parabola. The parabola's fixed line and fixed point are together referred to as the directrix and focus, respectively. It's also crucial to remember that the fixed point is not located on the fixed line. A parabola is a locus of any point that is equally distant from a given point (focus) and a certain line (directrix). An essential curve of the coordinate geometry's conic sections is the parabola.
For the given question,
Vertex of parabola is (-3,3)
Thus, the equation of the parabola is:
= 4(y-3)

substituting values
Answer:
2 5/6 inches
Step-by-step explanation:
58 1/2 to 58 3/6
55 2/3 to 55 3/6
add 6/6 to 3/6 and change 58 to 57
subtract
=2 5/6
B: x= -2/3 and x=1 might be the answer
Hello there!
For these, you can only add the numbers with the same index. For example, you can add x² and 2x², but not x³ and x².
So here, you can just look based on their indexes:
There are two with an index of 4:
4
and
.
You can add those, and you get 5
.
There's one with an index of 3: x³. So there's an +x³ in the final equation.
For those with an index of 2, there are two: x² and -x². Those two cancel out just to equal 0.
For just x, there's x, and -x. Those two cancel out as well.
There's the final -1.
So you're looking for:
5
+ x³ - 1, or C.
