A nursery plants a new tree and attaches a guy wire to help support the tree while its roots take hold. A
wire is attached mid-tree to a stake in the ground
that is 5 feet 6 inches from the base of the tree. The
angle created by the wire and the ground is 43°. How
long is the wire?

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
