Apraying mantis is an interesting insect that can rotate its head 108 degrees. suppose the praying mantis is 10.5 centimeters long. what mixed number represents this length?

dude   i don't even know. i've been trying for hours.

step-by-step explanation:

what is the original number? you forgot to add it.

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
