Answer:
zero point three two meter
Step-by-step explanation:
Given

Required
How should it be pronounced
From the measurement above, we can see that it contains a decimal point.
Using the rules of decimal point,
The number before the decimal point will be treated as 1 number and will be pronounced as such.
While numbers after the decimal will be treated as individual digits and will be pronounced individually.
Hence, the pronunciation of 0.32 meter is zero point three two meter
The formula of find the slope is -0.4285
use y2 - y1 over x2-x1
Answer:
The equation of the parabola is
.
Step-by-step explanation:
Since the directrix is of the form
, the parabola is vertical. The vertex of the parabola (
) is the midpoint between the focus (
) and a point of the directrix (
), that is to say:
(1)
If we know that
and
, then the coordinates of the vertex of the parabola:


The vertex factor (
) is the distance of the focus with respect to the vertex:
(2)
If we know that
and
, then the vertex factor is:


The equation of the parabola in the vertex form is described below:
(3)
Where:
- Independent variable.
- Dependent variable.
- Coordinates of the vertex.
If we know that
and
, then the equation of the parabola is
.
Here's a way to do it.
Let 4e +2 = 5n +1 . . . . . . for some integer n
Then e = (5n -1)/4 = n + (n -1)/4
We want (n-1)/4 to be an integer, so let it be integer m.
... m = (n -1)/4
... 4m = n -1
... 4m +1 = n
Substituting this into our expression for e gives
... e = (5(4m+1) -1)/4 = (20m +4)/4 = 5m +1
e = 5m+1 for any integer m
