The following equation predicts demand (ModifyingAbove y with carety) for electric power (in megawatts) at N. Y. Edison using the straight-line trend method over time in years (x). Which statement best describes the slope (b)? ModifyingAbove y with carety=56.76 + 10.54x A. At time zero, demand for electric power at N. Y. Edison is 10.54 megawatts. B. Each year demand for electric power at N. Y. Edison increases by 56.76 megawatts. C. Each year demand for electric power at N. Y. Edison increases by 10.54 megawatts. D. At time zero, demand for electric power at N. Y. Edison is 56.76 megawatts.

Quick calculate the roi dollar amount and percentage for these example investments. a. you invest $50 in a government bond that says you can redeem it a year later for $55. use the instructions in lesson 3 to calculate the roi dollar amount and percentage. (3.0 points) tip: subtract the initial investment from the total return to get the roi dollar amount. then divide the roi dollar amount by the initial investment, and multiply that number by 100 to get the percentage. b. you invest $200 in stocks and sell them one year later for $230. use the instructions in lesson 3 to calculate the roi dollar amount and percentage. (3.0 points) tip: subtract the initial investment from the total return to get the roi dollar amount. then divide the roi dollar amount by the initial investment, and multiply that number by 100 to get the percentage.
