An object moves in simple harmonic motion with period 7 seconds and amplitude 2cm . At time t=0 seconds, its displacement d from rest is -2cm , and initially it moves in a positive direction. Give the equation modeling the displacement d as a function of time t .

answer:     true

step-by-step explanation:

hi there!

first we need to find out how much they are adding to each number to make the next number.

ex: 4 + 4 = 8, 8 + 8 = 16, and so on.

so continuing with 32,

32 + 32 = 64

64 + 64 = 128

128 + 128 = 256

256 + 256 = 512

4, 8, 16, 32, 64, 128, 256, 512

the 8th term of the sequence will be 512

hope this ! ~
