What is the rule for the reflection? O ry-axis(x, y) - (-x, y)
O ry-axis (x, y) – (x –y)
Orx-axis(x, y) - (-x, y)
Orx-axis (x, y) - (x, -y)

probability for j is 1/4

while

a is 1/6

step-by-step :

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
