Write the vector u as a sum of two orthogonal vectors, one of which is the vector projection of u onto v, projvu u=(-9,3), v=(-9,3)

  u = v

Step-by-step explanation:

Vector u appears to be the same as v, so its decomposition is simply ...

  u = projvu = v

__

There is no orthogonal component.

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
