Round all computation to the nearest dollar.
Suppose that you drive 15,000 miles per year and gas averages $3.50 per gallon.
a. What will you save annual fuel expenses by owning a hybrid car averaging 60 miles per gallon rather than SUV averaging 15 miles per gallon?
b. If you deposit your monthly fuel savings await the end of each month into an annuity that pays 5. 7% compounded monthly, how much will you have saved at end of six years?

- 1. We want to graph the function f(x) log4 x. In a table below, = find at three points with nice integer y-values (no rounding!) and then graph the function at right. Be sure to clearly indicate any asymptotes.

- 3. Solve the inequality and give your answer in interval notation. Be sure to show all your work, and write neatly so your work is easy to follow. (4 points) 2|3x+12 ≥ 18arrow_forward- 2. In words, interpret the inequality |x8|> 7 the same way I did in the videos. Note: the words "absolute value" should not appear in your answer! (2 points)arrow_forward1. Define probability: 2.
