3. Daniel is climbing a ladder that reaches 15 feet above ground. He is currently y
feet above ground.
Write an equation to show how much
farther he will need to climb to get to the
top of the ladder?

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 %
