Answer:
The equation of parabola is given by : 
Step-by-step explanation:
Given that vertex and focus of parabola are
Vertex: (4,-3)
Focus:(
,-3)
The general equation of parabola is given by.
, When x-componet of focus and Vertex is same
, When y-componet of focus and Vertex is same
where Vertex: (h,k)
and p is distance between vertex and focus
The distance between two points is given by :
L=
For value of p:
p=
p=
p=
p=
and p=
Since, Focus is left side of the vertex,
p=
is required value
Replacing value in general equation of parabola,
Vertex: (h,k)=(4,-3)
p=



Answer:
She made a mistake in Step 7.
Step-by-step explanation:
Step 1 through 6 are correct. Only from Step 6 to Step 7 the problem comes in: both sides of the equation are multiplied by x, however the x on the left side, by error, becomes 1. The correct state in Step 7 should look like this:

Answer:
x = 2
Step-by-step explanation:
y = 
If the denominator is equal to zero , then y is undefined.
this discontinuity can be found by equating the denominator to zero and solving for x.
x - 2 = 0 ⇒ x = 2 is the point of discontinuity
Answer:
45 yards by 24 yards
Step-by-step explanation:
You would have to first find out how many 2.5 increments are in each of the two lengths. Then multiply that number by 15

sorry I'm not that good with math sorry if I waisted your time ^_^
