Answer:
Circle
Step-by-step explanation:
Examples of conic sections are the circle, the ellipse, the parabola and the hyperbola. Parametric equations are used to express the x and y variables in terms of a less complicated manner using a third variable (t or θ).
The parametric equation for a circle with an equation 
is given by:
where r is the radius of the circle and (h, k) is the center of the circle.
A conic section with a parametric equations X=3cos(t)-1, y=3sin(t)+4 is a circle with center at (-1, 4) and radius of 3. The equation of the circle is:
(x + 1)² + (y - 4)² = 3²
Answer:
its 3
Step-by-step explanation:
Answer:
8persons/group
Step-by-step explanation:
Give parameters:
Number fourth graders = 24
Number of groups = 3 groups
Unknown:
Number of students in each group = ?
Solution:
Solving this problem involves finding the number of persons per group.
Number of persons per group = 
Insert the parameters and solve;
Number of persons per group = 
= 8persons/group
If x equals the number, then seven times the number is 7x; three less than that is 7x-3.
Answer:
The variable X represents:
X = the number of books
The real world situation can be:
1.) Jennie reads books. She reads each books for
2.) Jennie wants to read book at least 5 books today.
Write an inequality that models the minimum number of books that Jennie needs to read.
The inequality for this situation is:
