In right triangle GHI, ∠H is a right angle, m∠I=42∘, and GH=11. sin42∘≈0.67 cos42∘≈0.74 tan42∘≈0.90 Triangle G H I has segment G H that measures 11 units. Angle H is a right angle and angle I is 42 degrees. What is the measurement of HI? If necessary, round your answer to two decimal places, like this: 42.53

yes

step-by-step explanation:

yes

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
