Suppose that you drive 40,000 miles per year and gas averages $4 per gallon.
a. What will you save annual fuel expenses by owning a hybrid car averaging 40 miles per gallon rather than SUV averaging 16 miles per gallon?
b. If you deposit your monthly fuel savings await the end of each month into an annuity that pays 5.2% compounded monthly, how much will you have saved at end of six years?

- Determine if each statement is true or false. If the statement is false, provide a brief explanation: a) There exists x = R such that √x2 = -x. b) Let A = {x = ZIx = 1 (mod 3)} and B = {x = ZIx is odd}. Then A and B are disjoint. c) Let A and B be subsets of a universal set U. If x = A and x/ € A - B,then x = An B.| E d) Let f : RR be defined by f (x) = 1 x + 2 1. Then f is surjective.arrow_forwardWrite the negation of the definition of an injective functionarrow_forwardLet U= {0, 1, 2, 3, 4, 5, 6, 7, 8, 9}, A = {xeU Ix is a multiple of 3}, and B = {x = UIx = 0 (mod 2)}.
