According to the Fundamental Theorem of Algebra, which polynomial function has exactly 8 roots? f (x) = (3 x squared minus 4 x minus 5) (2 x Superscript 6 Baseline minus 5) f (x) = (3 x Superscript 4 Baseline + 2 x) Superscript 4 f (x) = (4 x squared minus 7) cubed f (x) = (6 x Superscript 8 Baseline minus 4 x Superscript 5 minus 1) (3 x squared minus 4)

Jessa bought a yoyo from a company that claims that, with each retraction, the string rolls up by 60% of the original length. she sets up a tape measure and throws the yoyo 3 times. her data are charted below. throw length of string (feet) 1 3 2 1.8 3 1.08 jessa wants to find the sum of the length of string after 10 throws. what is the sum of the lengths, rounded to the nearest hundredth?
