A quadratic function models the profit of the company and the maximum/minimum value of the quadratic function occurs on its vertex.
The given function is:

The equation is already in standard form, the vertex of the parabola as seen from the equation is (5,12)
This mean if the company sets the price of socks to $5 they will earn a maximum profit which is $ 12 million
Answer:
27.2 ft
Step-by-step explanation:
Since 1 in on the drawing = 8 ft, we should find out how much ft is 3.4 in.
So, to get from 1 to 8, we multiply by 8.
And since we multiply by 8, we also have to do it to the other part as well.
So we would do:
8 x 3.4 = 27.2
Hope this helps! :)

Step-by-step explanation:
Answer:
x = 9
Step-by-step explanation:
Use the equation of the line, and let y = 0. Then solve for x.
y = 2/3 x - 6
Let y = 0:
0 = 2/3 x - 6
Add 6 to both sides.
6 = 2/3 x
Multiply both sides by 3/2.
3/2 * 6 = x
x = 9
