Order the expressions from the least value to the greatest value. 5/-1.6
-3 3/10 - (-7/10)
5 6/15 + (-2 4/5)
-4.5 x -2.3

Use the function nest to evaluate p(x) = 1 + x + · · · + x50 at x = 1.00001. (use the matlab ones command to save typing.) find the error of the computation by comparing with the equivalent expression q(x) = (x51 − 1)/(x − 1).

Apositive number a or the same number a increased by 50% and then decreased by 50% of the result?

2. explain in words how you plot the point (4, −2) in a rectangular coordinate system.
