2250= plastic beads
6750= metal beads
STEP 1:
Find total number of beads on clearance
= 2250 + 6750
= 9000 total beads on clearance
STEP 2:
set a ratio; number of plastic beads on clearance to the total number of beads on clearance is what number out of 100
x= percent out of 100
2250/9000= x/100
cross multiply
(9000*x)= (2250*100)
9000x= 225,000
divide both sides by 9000
x= 25%
CHECK:
multiply total number of beads by 25%
= 9000 * 25%
= 9000 * 0.25
= 2250 number of plastic beads
ANSWER: 2250 beads is 25% out of the total number of beads on clearance.

The type of transformation that preserves the symmetry is Vertical translation.
For instance, a parabola is still symmetric about the y-axis if you move it up. It loses its symmetry if you move it to the left or right. Reflection keeps both even and odd functions symmetrical.
<h3>
What is the difference between even and odd function ?</h3>
The symmetry of a function is described using the terms even and odd. On a graph, an even function is symmetric about the y-axis. An odd function has symmetric behavior around a graph's origin . This means that if you rotate an odd function 180 degrees around the origin, the function you started with will still exist.

Answer:
The quadratic function represented by the graph is .
Step-by-step explanation:
Parabolae are defined by second order polynomials, that is, a polynomial of the form:
(1)
Where:
- Independent variable.
- Dependent variable.
- Coefficients.
By Algebra, we know can calculate the set of all coefficients based on the knowledge of three distinct points. According to the graph, we have the following points: , and , and the resulting system of linear equations is:
(2)
(3)
(4)
The solution of the system of linear equations is:
Hence, the quadratic function represented by the graph is .
