Delete AC and focus on the intersection of AB and BC. Keeping points B and C fixed, move point A to different locations and observe how ZABC changes. What must you do to increase or decrease m ABC ? What happens if you move point A to a location directly on CB? What is
mZABC at this location?

Hello admin your succk

Step-by-step explanation:

2 is the final ! : )

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
