Rays: XW, XŹ, ZX, ZY
Rays: XW ZY
Lines: XZ, XW ZY

Rays: XW, ZY
Lines: XZ
Rays: XW XŻ, ZY
O
Lines: xz
Lines: xż

2nd Option is correct

Step-by-step explanation:

As :

Lines are - XZ, XW, ZY

Rays are - XW, ZY

BTW, you can answer the question by just seeing the options as well as figure.

WKT, a line is having 2 end points. So just see the options. Only 1 option is having 3 lines others are just having 1, but we can see in image that there are so many line segments having end points.

So, we can conclude that 2nd option is correct as we are seeing 3 lines in it..

Thanks

Hope it helps

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
