What are the dimensions of a matrix representing a vector on the coordinate plane? Explain your response.

if you use photomath right away it will give you the answer not like this app that you have to wait for people.

hey! so 1 (25) out of 4 (100) is 25 so your answer is 25%. it's like quarters!

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
