Persamaan lingkaran yang pusat O(0, 0) dan melalui titik (3, -2) adalah ….   a. x2 + y2 = 13 b. x2 + y2 = 4 c. x2 + y2 = 9 d. x + y = 18 e. x2 + y2 + 6 = 0

i believe the answer is d.

hope it you! : d

step-by-step explanation:

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
