2. The sum of the third and the seventh terms of an AP is 6 and their product is 8. Find
the sum of first sixteen terms of the AP.

Segment xz is bisected by point y. if xy = 12x, and the measure of xz = 18x – 6, solve for x

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 %
