Suppose that you earned a bachelor's degree and now you're teaching middle school. The school district offers teachers the opportunity to take a year off to earn a master's degree. To achieve this goal, you deposit $1500 at the end of every three months in an annuity that pays 5.5% compounded quarterly. How much will you have saved at the end of 6 years? Find the interest.

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 %
