The ordering and transportation cost C for components used in a manufacturing process is approximated by C(x) = 10 (1/x + x/ (x+3)) where C is measured in thousands of dollars and x is the order size in hundreds.
(a) Verify that C(3) = C(6).
(b) According to Rolle’s Theorem, the rate of change of the cost must be 0 for some order size in the interval (3, 6). Find the order size.

Marcus needs to rewrite f(x) = x2 + 6x + 4 in vertex form.

Isuck at math ; ^; m a student solved this problem and said the answer is 3 feet. chase had a roll of ribbon that contained 7 7/8  feet of ribbon. he cut off one piece that was 3 5/8  feet long and another piece that was 1 1/4  feet from the roll. how much ribbon was left on the roll? is the student's answer reasonable? yes, the answer is reasonable. no, the answer is not reasonable. it should be about 2 feet. no, the answer is not reasonable. it should be about 13 feet. no, the answer is not reasonable. it should be about 4 feet.
