Suppose a publishing company estimates that its monthly cost is C(x) = 600x ^ 2 + 300x and its monthly revenue is R(x) = - 0.4x ^ 3 + 700x ^ 2 - 600x + 500 , where xis in thousands of books sold. The profit is the difference between the revenue and the cost What is the profit function, P(x)

Step-by-step explanation:

Given: Monthly cost :

Monthly revenue : , where x is in thousands of books sold.

Profit = Revenue - Cost

Now , Profit function : P(x) =  R(x)-C(x)

Hence,

step-by-step explanation:

hans did not square the 40-unit side; he merely multiplied it by 2.   incorrect.

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.
