C. All of the above. Both formulas represents in calculating the slope.
<u>Step-by-step explanation:</u>
The slope(m) can be identified by the formula rise over run.
i.e. .
Rise is how much the line gone vertically ( y-axis) from the origin.
Run is how much the line gone horizontally (x-axis) from its origin.
∴ Rise =
And Run = .
⇒ .
Thus both equations can be used to find the slope of the line intercept.
If the points are given you can chose them yourself from the graph. Just consider any two points on the line.
Using the vertex of a quadratic function, it is found that:
a) The revenue is maximized with 336 units.
b) The maximum revenue is of $56,448.
<h3>What is the vertex of a quadratic equation?</h3>A quadratic equation is modeled by:
The vertex is given by:
In which:
Considering the coefficient a, we have that:
- If a < 0, the vertex is a maximum point.
- If a > 0, the vertex is a minimum point.
The demand function is given by:
p(x) = 336 - 0.5x.
Hence, the revenue function is:
R(x) = xp(x)
R(x) = -0.5x² + 336x.
Which has coefficients a = -0.5, b = 336.
Hence, the value of x that maximizes the revenue, and the maximum revenue, are given, respectively, as follows:
