Answer:
5571.99
Step-by-step explanation:
We need to use the Pythagorean theorem to solve the problem.
The theorem indicates that,
Once this is defined, we proceed to define the volume of a cone,
Substituting,
We need to find the maximum height, so we proceed to calculate h, by means of its derivative and equalizing 0,
then
<em>We select the positiv value.</em>
We have then,
We can now calculate the maximum volume,
The equation for the red graph is f(x) = -x².
<h3>How to depict the equation?</h3>From the information given, g(x) = 4 - x².
The vertex of the point (0, 4) and (0, 0) for g(x) and f(x) respectively. The rule of the translation will be:
(x, y) = (x, y -4).
The equation of the function will be:
f(x) = g(x) - 4
f(x) = (4 - x²) - 4
f(x) = -x²
