El siguiente circuito en paralelo con una fuente de energia de 200v, dos lamparitas, un aire acondicionado de 3200watts, una llave termica de 20A y una tecla de encendido que representa a una llave. si en un determinado momento se cierra la llave, responda a las siguientes preguntas:a) ¿El aire acondicionado puede funcionar en estas condiciones?b) ¿cuanta corriente electrica entrega la fuente de energia al circuito?

(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.)

The temperature at a point (x, y) is t(x, y), measured in degrees celsius. a bug crawls so that its position after t seconds is given by x = 6 + t , y = 8 + 1 3 t, where x and y are measured in centimeters. the temperature function satisfies tx(3, 9) = 5 and ty(3, 9) = 4. how fast is the temperature rising on the bug's path after 3 seconds? (round your answer to two decimal places.)
