State ac in simplest radical form ( )

Here, triangle ABC is a right triangle with AB = AC. It mens its a 45-45-90 special triangle .

So we need to use the formula that determines the relationship between legs and hypotenuse and the formula is

In the given diagram, leg = 12, so hypotenuse AC

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

i think the answer is true
