the ratio of the sides of two similar polygons is 50:21 . the side of the smaller polygon is 11. what is the side of the larger polygon

26.19

Step-by-step explanation:

If you put them into a ratio you will find (x/11)=(50/21). After cross multiplication, you will get (11)(50)=(21)(x). After solving the equation you get x to be 26.1905

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
