Question

GUYS PLEASE ANSWER! I'M DESPERATE! WILL MARK BRAINLIEST

Answer 1

A. Graph B because the slope is at a constant rate
B. Graph A because since it is slowly opened the rise of the slope starts of small then rises more
C. Graph C since it’s opened a lot the beginning and closed at the end so the rise would start high then go lower as time goes by

Answer 2

Answer:

A) The graph that best represents the amount of water in the barrel filled by the green hose is graph B. I know this because the green hose is filling the barrel at a constant rate, and graph B shows a constant rate of change, as it's a perfectly straight line increasing.

B) The graph the best represents the amount of water in the barrel filled by the black hose is graph A. This is because the information states that the black hose filled the water at a slow rate at first, since it was slowly being opened, and graph A clearly depicts the rate slowly increasing.

C) The graph that best represents the amount of water in the barrel filled by the blue hose is graph C. I know this because the information states that the blue hose is filling up the barrel normally, but is then slowly closed towards  the end. Graph C clearly shows the rate increasing then slowing down.
