Linda
bought a circular tablecloth that has a radius of 3 feet. what is the circumference to the nearest foot of linda's tablecloth

6

Step-by-step explanation:

The circumference is always x2 of the radius

the final price would be 29.6925

step-by-step explanation:

39.59 minus 25% equals 29.6925

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
