Answer:
-19. Cant be -6 as its to the right. the others are positive.
Answer:
f(6) = -5
f(x) = 0 and x=1 and x=5
Step-by-step explanation:
f(6) is the value when x=6
looking at the graph when x=6 f(6) = -5
f(x) = 0 means the y value is 0 This occurs when x = 1 and x=5
Speed = 225 metres per minute
Distance = 15 km = 15,000 metres
---------------------------------------------------
s=d/t
ts=d
Therefore: t=d/s
--------------------------------------------------
Time = Distance / Speed
Time = (15,000 metres) / (225 metres per minute)
--------------------------------------------------
