A toy company has determined that the revenue generated by a particular toy is modeled by the following equation: 10x - 0.025x²
Digiron [165]

Answer:

Maximum revenue = 1000 thousands of dollars.

Explanation:

We have the revenue equation r(x)=10x - 0.025x^2, where x is measured in thousands of toys produced, and r(x) is measured in thousands of dollars.

At maximum revenue the derivative of equation is zero

So, r'(x)=0\\ \\10 - 0.025*2x=0\\ \\ x=10/0.05\\ \\ x=1000/5=200

So maximum revenue is when 200 thousands of toys are produced.

Maximum revenue, r(200)=10*200 - 0.025*200^2\\ \\ r(200)=1000

Maximum revenue = 1000 thousands of dollars.

2(x + 4)= -5 + 1 what is this answer
fiasKO [112]

Answer:

x=-6

Step-by-step explanation:

Given Equation:

                    2(x + 4)= -5 + 1

Solving the Equation for 'x':

                  2(x + 4)= -4

              2(x) + 2(4)= -4\\

                      2x+8=-4

Subtracting '8' both sides:

                        2x=-4-8

                        2x=-12

Dividing by '2' both sides:

                         x=-12/2\\

                           x=-6

The Solution for the equation is:  x=-6
