Answer:
or 12.5
Step-by-step explanation:
So if 25 - x items are sold, and they each cost x, we can write an equation for the revenue to be
y = (25 - x)x
The vertex of this equation will represent the maximum revenue. So we need to write this equation in vertex form so we can find the vertex.
Vertex from is
y = a(x - h)^2+ k,
where (h,k) represent the vertex.
the vertex form of this equation would be
And the vertex would be
This means the maximum revenue will occur when x = 25/2
Answer:
The answer to your question is the letter D. (x - 11)² + (y - 6)² = 72
Step-by-step explanation:
Data
Equation = ?
Center = (11, 6)
Point = (17, 12)
Process
1.- Calculate the length of the radius using the distance between two points formula.
d = 
x1 = 11 y1 = 6
x2 = 17 y2 = 12
-Substitution
d = 
d = 
d = 
d = 
radius =
2.- Write the equation of the formula
(x - 11)² + (y - 6)² = ()²
Result
(x - 11)² + (y - 6)² = 72
52 divided by 8 = 6.5 hope this helps you!
