What is the length of ac ? enter your answer in the box. units triangle a b c with vertical side a c. vertex b lies to the right of side a c. angle a and angle c are marked congruent. the length of side a c is labeled as x. the length of side a b is labeled as x plus 4. the length of side b c is labeled as 3 x minus 8.

Proceed as in example 3 in section 6.1 to rewrite the given expression using a single power series whose general term involves xk. ∞ n(n − 1)cnxn − 2 n = 2 − 4 ∞ ncnxn n = 1 + ∞ cnxn n = 0

Evaluate cos2θ for cosθ = square root of 3/2

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 %
