Answer:
The total cost in dollars of going to the baseball game for
people of a family can be given as:
Step-by-step explanation:
Given:
At a baseball game:
Cost of car parking = $5
Cost per ticket = $21
To write an equation in the form of representing the total cost of going to the baseball game.
Solution:
The total number of people in the family is =
Using unitary method to find the cost of tickets for persons.
If 1 ticket costs = $21
<em>Then, tickets will cost in dollars</em><em> = </em>
Fixed rate for car parking = $5
Thus, the total cost in dollars of going to the baseball game for
people of a family can be given as:

The endpoints of the latus rectum are and
.
Step-by-step explanation:
A parabola with vertex at point and whose axis of symmetry is parallel to the y-axis is defined by the following formula:
(1)
Where:
- Independent variable.
- Dependent variable.
- Distance from vertex to the focus.
,
- Coordinates of the vertex.
The coordinates of the focus are represented by:
(2)
The <em>latus rectum</em> is a line segment parallel to the x-axis which contains the focus. If we know that ,
and
, then the latus rectum is between the following endpoints:
By (2):
By (1):
There are two solutions:
Hence, the endpoints of the latus rectum are and
.
