What is the correct answer to this problem?

Y=51.34019175

Step-by-step explanation:

We first use Pythagoras theorem to find the hypo...

After we use sine rule

12.8062487/sin90 = 10/siny

Sin y=10sin90/12.8062487

Y=51.34019175

whats the question?

step-by-step explanation:

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
