1. A mechanical metronome is set to “click” at 120 beats per minute (bpm). The end of the metronome arm swings out a maximum of 3 inches from the vertical rest position. What simple harmonic motion equation could model the position of the end (in terms of distance from vertical rest position) of the metronome arm as a function of time?

6 cm

step-by-step explanation:

she will sew have sewn five dresses   and be 1/3 done with the sixth one in an hour.

step-by-step explanation:

3/4 of an hour=45 mins

lucy makes 1 dress per 11.25 minutes

45 mins+11.25 mins=56.25 mins

60 mins- 56.25 mins=3.75 mins

3.75 mins is 1/3 of of 11.25 mins

therefore she the other 1/3 would be part of the hour and she will have sewn 5 dresses and begun the sixth.
