Two factory plants are making TV panels. Yesterday, Plant A produced 12,000 panels. Five percent of the panels from Plant A and 1% of the panels from Plant B
were defective. How many panels did Plant B produce, if the overall percentage of defective panels from the two plants was 4%?
Number of panels produced by Plant B: 0

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225

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

he has now walked a total of what?

if i know what this is maybe i can
