El calor especifico del agua es de 4184 J/kg ·K ¿en cuantos joules cambia la energia interna de 50 g de agua cuando se calienta desde 21ºC hasta 37ºC? Suponga que la dilatacion del agua es despreciable el calor añadido para aumentar la temperatura del agua es AQ= cm Ar = (4184J/kg·K) (0.050 kg)(16ºC)=3.4x10´3J

Which of the statements about the graph of the function y = 2x are true? check all of the boxes that apply. the domain is all real numbers x because the exponent of 2 can be any real number when the x-values increases by 1 unit, the y-value multiplies by 2. the y-intercept is (0, 1). the graph never goes below the x-axis because powers of 2 are never negative. the range is all real numbers.

Evaluate this using ! 0.25^2 x 2.4 + 0.25 x 2.4^2 − 0.25 x 2.4 x 0.65

What is the inverse of the function f(x) = 2x + 1?
