Atoy company has determined that the revenue generated by a particular toy is modeled by the following equation: 10x - 0.025x² the variable x is measured in thousands of toys produced, and r(x) is measured in thousands of dollars. what is the maximum revenue the company can earn with this toy?

Maximum revenue = 1000 thousands of dollars.

Explanation:

We have the revenue equation , 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,

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

Maximum revenue,

Maximum revenue = 1000 thousands of dollars.

the answer is b

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,
