Answer:
(5, - 4)
Step-by-step explanation:
Given a quadratic in standard form : ax² + bx + c : a ≠ 0
Then the x- coordinate of the vertex is
= - 
x² - 10x + 21 ← is in standard form
with a = 1, b = - 10, so
= - 
= 5
Substitute x = 5 into the quadratic for the corresponding value of y
y = 5² - 10(5) + 21 = 25 - 50 + 21 = - 4
vertex = (5, - 4)

<h3>What is a linear equation?</h3>
- A linear equation has one or two variables.
- No variable in a linear equation is raised to a power greater than 1.
- No variable is used as the denominator of a fraction.
- A linear equation is defined as an equation that is written in the form of ax+by=c.
- When solving the system of linear equations, we will get the values of the variable, which is called the solution of a linear equation.
- solving this we will get the valve of Y if x is given.
y=1/20 X²
let x=10 ( the largest dimension of the pendant is 10 cm wide)
y=1/20 *(10)²
y=1/20 *100
y= 5 cm (answer)
