1. belinda needs $2400 fast. she has the option of borrowing the $2400 for 5 days at an apr of 500% or borrowingthe $2400 for 5 days with a fee of $180. she realizes that neither scenario is very good, but she wants to choose theoption that is best for her. belinda decide which is the "better" deal. (5 points: part 1 - 1 point; part 11 - 1 point, part iii - 1 point; part iv-1 point; part v- 1 point)part i: what is the length of the period of the $2400 loan for 5 days for a fee of $180? part ii: what is the number of periods for 1 year? part iii: what is the periodic interest rate of the $2400 loan for 5 days for a fee of $180? part iv: what is the apr of the $2400 loan for 5 days for a fee of $180?

1. when "a" is a root of a polynomial, (x -a) is a factor of it. for the three roots given, the factors of the desired polynomial are (x +2)(x -1/2)(x -3).

in order to make the leading coefficient be negative, we need to multiply this product by a negative number. any negative number will do, but we choose a small (magnitude) value that will eliminate the fraction: -2.

then

f(x) = -2(x +2)(x -1/2)(x -3) = -(x +2)(2x -1)(x -3)

= -(2x² +3x -2)(x -3)

= -(2x³ -3x² -11x +6)

f(x) = -2x³ +3x² +11x -6

2. a graph created by the desmos on-line graphing calculator is shown, and the zeros are highlighted.

3. as indicated in part 1, the multiplier of this equation can be anything and the zeros will remain the same. you want a negative leading coefficient, so the "anything" is restricted to any of the infinite number of numbers that will make that be the case.

his answer is incorrect. i just used it, and it said it was incorrect. the answer is 0.
