No it is not the same thing.
Answer:
27
Step-by-step explanation:
To evaluate f(8) substitute x = 8 into f(x)
f(8) =
× 8² - (
× 8 + 3)
=
× 64 - (2 + 3)
= 32 - 5
= 27
Answer:
1.15
Step-by-step explanation:
P/n = 1.15
Price is 1.15 per kiwi
The zeros of this function is when y = 0.
(x, 0) and (x,0)
Looking on the graph
It would be (3,0) and (6,0)
The solution is x = 3, x = 6
Continuing from the setup in the question linked above (and using the same symbols/variables), we have




The next part of the question asks to maximize this result - our target function which we'll call

- subject to

.
We can see that

is quadratic in

, so let's complete the square.

Since

are non-negative, it stands to reason that the total product will be maximized if

vanishes because

is a parabola with its vertex (a maximum) at (5, 25). Setting

, it's clear that the maximum of

will then be attained when

are largest, so the largest flux will be attained at

, which gives a flux of 10,800.
