Using Lagrange multipliers, we have the Lagrangian
with partial derivatives (set equal to 0)
Substituting the first three equations into the fourth allows us to solve for
:
For each possible value of
, we get two corresponding critical points at
.
At these points, respectively, we get a maximum value of
and a minimum value of
.
The value of x is: Solve for x by simplifying both sides of the equation, then isolating the variable.
x=−9/4
21,800,000 rounded to the nearest million = 22,000,000
Answer:
Center is at (0,0)
Step-by-step explanation:
An equation of ellipse in standard form is:
Where center is at point (h,k)
From the equation of . First, we add 45 both sides:
Convert into the standard form with RHS (Right-Hand Side) equal to 1 by dividing both sides by 45:
Therefore, the center of ellipse is at (0,0) since there are no values of h and k.
