Tom is trying to write 3 over 61as a decimal. He used long division and divided until he got the quotient 0.0491803279, at which point he stopped. Since the decimal doesn't seem to terminate or repeat, he concluded that 3 over 61 is not rational(the decimal does not end).

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

make sure you have version 2.50

you have to wait a while to reward brainliest if only one person answers. if 2 people answer there should be a "mark brainliest" on their question.
