The per-unit price p (in dollars) of a popular toy when x units (in thousands) are produced is modeled by the function 12-0.025x p = 12 − 0.025 x . The revenue (in thousands of dollars) is the product of the price per unit and the number of units (in thousands) produced. So the revenue function is given by r ( x ) = x p , or rather: r ( x ) = x ( 12 − 0.025 x ) According to this function, how many single units should be produced for the revenue to equal $440,000? There will be two answers, type the least answer into the box. Be careful with units, remember that x represents thousands of units and r ( x ) represents thousands of dollars.

Acable company wants to provide cell phone service for residents on an island. the function for the cost of laying the cable from the island to the mainland is c(x)= 6.500 square root x2+4, where x represents the length of the cable in feet. what are the domain and range of the function? a) domain: all real numbers range: all real numbers greater than or equal to 17,000 b) domain: all real numbers greater than or equal to 0 range: all real numbers greater than or equal to 17,000 c) domain: all real numbers greater than or equal to 0 range: all real numbers greater than or equal to 13,000 d) domain: all real numbers greater than or equal to 13,000 range: all real numbers greater than or equal to 0
