Δefg is dilated from the origin at a scale factor of 2 to create δe′f′g′.
select the option that completes the statement:
the triangles' corresponding sides are and their corresponding angles are ; therefore, the triangles are
congruent; similar; proportional
congruent; proportional; similar
proportional; congruent; similar
proportional; similar; congruent

  proportional; congruent; similar

step-by-step explanation:

dilation changes the scale so that lengths are proportional and angles are unchanged. the appropriate statement is

  the triangles' corresponding sides are proportional, and their corresponding angles are congruent; therefore, the triangles are similar.

the answer is the triangles' corresponding sides are proportional, and their corresponding angles are congruent; therefore, the triangles are similar.

this is because a dilation only changed the side length of the triangle using the common scale factor and did not change the angle measurements.

hope this !

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
