126

Step-by-step explanation:

angle ZWY = 180 - 90 - 63 = 27

Base on the given information, the length of XW is same with the length of ZW, which means they have the same angle.

Quadrangle has angle of 360

360(quadrangle) - 27(ZWY)- 27(XWY) - 90(WZY) - 90(WXY)

= 126

12cm

the answer is d

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
