Graph the image of the figure after a dilation with a scale factor of 1/2 centered at (−1, 3) . use the polygon tool to graph the triangle by connecting all its vertices.

see attached diagram

Step-by-step explanation:

Given triangle has vertices at points B(-5,3), C(-5,7) and D(1,7). The center of dilation is point A(-1,3) and the factor of dilation is The dilation by a factor decreases lengths AB, AC and AD twice, then image triangle vertices are midpoints of segments AB, AC and AD.

1. The midpoint E of the segment AB has coordinates

2. The midpoint F of the segment AC has coordinates

3. The midpoint G of the segment AD has coordinates

true !

step-by-step 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
