Suppose the probability of selling a car today is 0.28. find the odds against selling a car today.

There is a line with slope 1/a going through the point (a, a²). find the equation of the line perpendicular to this line at this point. (don’t let this problem intimidate you! solve the problem as you would if i’d given you specific values. just use variables instead.)

Which of the following is missing in the explicit formula for the compound interest geometric sequence below?
