The level of water in a tank is decreasing such that its depth, d, can be modeled by d =18(.92)", where h represents the hours that the tank has been draining. Based on the model, which of the following represents
the percent that the water level drops in the span of a single day?

The edge of a cube was found to be 30 cm with a possible error in measurement of 0.4 cm. use differentials to estimate the maximum possible error, relative error, and percentage error in computing the volume of the cube and the surface area of the cube. (round your answers to four decimal places.) (a) the volume of the cube maximum possible error cm3 relative error percentage error % (b) the surface area of the cube maximum possible error cm2 relative error percentage error %
