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?

8(-10x+3.5y-7)

8×-10x + 8×3.5y + 8×-7

-80x + 28y - 56

therefore

-80x+28y-56 is the correct answer

trapezoid

step-by-step explanation:

first i plotted all my points on a grid graph

i made sure all of them were in the correct quadrant

then i saw it was a trapezoid or a quadrilateral

hi how are you doing today? if you ever need just tell me
