Answer:
5
Step-by-step explanation:
Calculate the distance d using the distance formula
d = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = (2, 4) and (x₂, y₂ ) = (5, 0)
d =
=
= =
= 5
Texaschic nailed it when saying that it's arithmetic
The recursive way to write this is to say
which tells us "start at 6 and each time subtract off 5"

Answer:
The standard form of the parabola is
Step-by-step explanation:
The standard form of a parabola is
.
In order to convert into the standard form, we first separate the variables:
we now divided both sides by 2 to remove the coefficient from and get:
.
We complete the square on the left side by adding 3 to both sides:
now we bring the right side into the form by first multiplying the equation by
:
and then we multiplying both sides by to get
.
Here we see that
Thus, finally we have the equation of the parabola in the standard form:
