Answer:
sorry I can't help you. ...............
Step-by-step explanation:
In this problem, we are asked to declare statements that describe the orders given as stated. In the first command, we are to define the element number of the element specified, which by, in this case, is oxygen. This is expressed: Element number = 8. Then we name the element that is element = oxygen. The third command specifies the atomic weight of the elementoxygen = 15.9994. For the last command, the expression is atomic weight = oxygen. It is important to arrange the commands in order so that the program that understands the data executes the orders well and translate them into output.

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
.
