ActivLife Incorporated determines that the revenue generated by producing and selling x of their LifeMax ellipticals can be modeled by the function R(x) = - * + 170x x 2 0 17 where x represents the number of ellipticals produced and sold, and R(x) represents the revenue in dollars. Determine msec on the closed interval [9, 20]. (Round your answer to two decimal places.) msec Interpret the result. The revenue generated by producing and selling the LifeMax elliptical is increasing on average by approximately $ per elliptical from the 9th to the 20th elliptical sold. Submit Answer 8.

MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER The Brimfield Company computes their profit function for making and selling x touch-screen ski gloves can be modeled by the function P(x) = - * + 23x - 5 [0, 70] 4 where x represents the number of gloves sold, and P(x) represents the profit in dollars. Determine the average rate of change in profit as the number of gloves produced and sold increases from 25 to 55. The profit generated by making and selling the ski gloves was increasing on average by $ per ski glove from the 25th to the 55th glove sold.The revenue and cost function are given. R(x) = 55x - 0.55x2; C(x) = 4x + 3 (a) Determine the break-even points. (Round your answers to two decimal places.) (x, y ) = ( (smaller x-value) ( x, y ) = (larger x-value) (b) Determine how much revenue must be generated to reach the break-even points. (Enter your answers as a comma-separated list. Round your answers to two decimal places.)
