The answer to your question is   k =

Step-by-step explanation:

Equation

                            5 - vk = k

Process

1.- Add vk in both sides

                          5 - vk + vk = k + vk

2.- Simplification

                           5 = k + vk

3.- Factor k (like terms)

                           5 = k(1 + v)

4.- Divide both sides by "1 + v"

                           5 / (1 + v) = k(1 + v) / (1 + v)

5.- Simplify

                           5 / (1 + v) = K

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

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
