Ethan has a map of his town. Three streets form a triangle. He measured the angles between the streets and the lengths of the streets on the map. He lives on street AC and knows it is 0.4 miles long. Which of the following statements are true? Select all that apply.

it would to have a graph or something ! but i had this question so its false

step-by-step explanation:

true

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
