Jada is putting a border around her rectangular garden. The garden is 12.63 meters long and 3.28 meters wide. This image shows a rectangular garden having a length of 12.63m and width of 3.28m.

Part A

Jada estimates the perimeter of her garden by rounding the length and width to the nearest whole number. Which equation shows her estimate?

A. 10 + 5 + 10 + 5 = 30 meters

B. 12 + 3 + 12 + 3 = 30 meters

C. 13 + 3 + 13 + 3 = 32 meters

D. 13 + 4 + 13 + 4 = 34 meters

Steam is generated in a boiler of a cogeneration plant at 10 mpa and 450°c at a steady rate of 5 kg/s. in normal operation, steam expands in a turbine to a pressure of 0.5 mpa and is then routed to the process heater, where it supplies the process heat. steam leaves the process heater as a saturated liquid and is pumped to the boiler pressure. in this mode, no steam passes through a condenser, which operates at 20 kpa. (a) determine the power produced in the turbine and the rate at which process heat is supplied in this mode. (b) determine the power produced in the turbine and the rate of process heat supplied if only 60 percent of the steam is routed to the process heater and the remainder is expanded to the condenser pressure. (3.32 mw; 9.69 mw; 4.25 mw; 5.82 mw)

(a) assume the equation x = at^3 + bt describes the motion of a particular object, with x having the dimension of length and t having the dimension of time. determine the dimensions of the constants a and b. (use the following as necessary: l and t, where l is the unit of length and t is the unit of time.) (b) determine the dimensions of the derivative dx/dt = 3at^2 + b. (use the following as necessary: l and t, where l is the unit of length and t is the unit of time.)
