triangle def has vertices located at d (2, 1), e (3, 5), and f (6, 2).

part a: find the length of each side of the triangle. show your work. (4 points)

part b: find the slope of each side of the triangle. show your work. (3 points)

part c: classify the triangle. explain your reasoning. (3 points)

is there answer choices?

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

7.25

step-by-step explanation:

we know that 7 equals to 7.0. we also know that 1/4=0.25. so we can add the two together and we get 7.25
