Jeanette uses 2 1/2 more balls of yarn to knit a blanket than she uses to knit a sweater. Knitting a sweater requires three times as much yarn as knitting a hat. Jeanette uses 1 1/2 balls of yarn to knit a scarf, which is 1/2 ball more than shes uses for a hat

what i would say the best answer is a. 40.5

step-by-step explanation:

duck you

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.

think the answer is 30 degrees. if not than it is 20 degrees. not 100% sure. let me know if it was right.
