Which of the following is the equation of an ellipse centered at (5,1) having a vertical minor axis of length 4 and a major axis of length 6?

Options are in image

D

Step-by-step explanation:

Any ellipse has the following equ

ation:

where

(as in the picture)

So it should be like:

Since it should be moved to the right and up, the answer would be:

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204
