Question1: A piston moves up and down in a cylinder. In this simulation, it takes 3 seconds for the
piston to complete one cycle. If the low position of the piston is y = 2 cm and the high
position of the piston is y = 22 cm. Which function would be used to model this situation?
a, y = 10 sin42 + 12
C. y = 12 sine + 10
b. y 10 sint + 12
d. y = 12 sin + 10

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m

853.3

step-by-step explanation:

c: y > - 1/6x + 1

step-by-step explanation:

dashed line - meaning this < or > also not equal

solid line - meaning this < or > also equal

your answer is c because y > means up & it's shaded up, but y < means down

hope this ! : )
