The Lagrangian,
has critical points where its partial derivatives vanish:
tells us
, so that
Then with , we get
and tells us
Then there are two critical points, . The critical point with the negative
-coordinates gives the maximum value,
.
1.) The error is that she attached the
variable with the flat fee (which is
constant) and put the daily rent as a
constant (which is variable).
The correct equation is:
365+125x=250+175x
2.) N=5
3.) k=-35.
Explanation: Solution:
17k-6=37k+4 . 17k-37k=4+6 .
-27k=10 . k=10\cdot(7-2) . k=-35 .
4.)
.
Answer:
The quotient = x + 5 and the remainder = 20
Step-by-step explanation:
The quotient = x + 5 and the remainder = 20
