Evaluate the expression when b=3 and c=6.

8

Step-by-step explanation:

dear! mam /sir!

solution;

given: b=3 and c=6.

=(6^2-4*3)/3

=(36-12)/3

=24/3

=8

hope it hlps..thank u!!

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
