Find the zeros and their multiplicities. Consider using Descartes' rule of signs and the upper and lower bound theorem to limit your search for rational zeros. f (x) = 20x3 - 47x2 + 11x + 6 Select one: a. - 14, 35, and 2 (each with multiplicity 1) b. -1, 3, and 2 (each with multiplicity 1) c. 14, - 35, and -2 (each with multiplicity 1) d. 1, -3, and -2 (each with multiplicity 1)

i dont know sorry

step-by-step explanation:

during a tunnel construction project, engineers used explosives to excavate partway into a mountain. but due to constraints and environmental concerns, they later introduced a tunnel boring machine (tbm) to excavate the rest of the tunnel. the length and of the completed tunnel (in feet) is based on the number of days since the tbm started working. the length can be calculated using the equation y = 25x + 225. what does the y-intercept represent in this scenario?

answer

the correct answer is option c

explanation

we have

we simplify as follows;
