Use the fundamental theorem of algebra to determine the number of roots for each polynomial function shown. 1.) f (x) = 2x3 + x2 - 7x + 1 has roots. 2.) f (x) = -3x + 5x2 + 8 has roots. 3.) f (x) = (x2 + 6)2 has roots.

answer: given that the roller coaster can accommodate 1600 riders per hour, thus the roller coaster can accomodate 1600 / 60 = 26.67 riders per minute.

given that there are 345 people in the line, the number of minutes it will take for the 345 persons to get into the roller coaster is given by 345 / 26.67 = 12.94 minutes.

therefore, it will take you 12.94 minutes to get to the front of the line.

the expression (1.26)2t reveals the approximate rate of increases in the number of plants semiannually.

hope this : )
