A survey team is trying to estimate the height of a mountain above a level plain. From one point on the plain, they observe that the angle of elevation to the top of the mountain is 32°. From a point
2000 feet closer to the mountain along the plain, they find that the angle of elevation is 35º.
How high (in feet) is the mountain?

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

idk the answer i want to say 10 but then it would be equal so try 9 but then yeah so yeah we love edgen

sorry i just need to anwers this to get points
