A toy car costing $60 is reduced by 15% in the sale. How much does it cost now?

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).

For the equations below which statement is true ? -2x=14 6x=-42

How do i do this activity, is appreciated
