Ineed asap! i will give 30pts to the person that has the best, and correct answer.

The answer is the square root (√) of 8/9

Step-by-step explanation:

The fraction is 64/81, and if you find the square root of 64 and 81 respectively, the numbers are 8 and 9. So, the square root of 64/81 is 8/9.

i believe its "c" because all of the other options include a but it could be d because there is a way of financing with cash at certain places but its uncommon.

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
