An object moves in simple harmonic motion with period 7 seconds and 4cm amplitude . At time t=0 seconds, its displacement d from rest is -4cm , and initially it moves in a positive direction. Give the equation modeling the displacement d as a function of time t .

Mrs. valdez wanted to determine the number of people, p, she could safely take in her car to the fun run. she determined that p < 5. which statement best describes a possible number of people she can take in her car? mrs. valdez can take –2 people because –2 < 5. mrs. valdez can take 2 people because 2 < 5. mrs. valdez can take 3.5 people because 3.5 < 5. not this mrs. valdez can take 5 people because 5 < 5. its not c what is the first step in solving the inequality < –1? multiply both sides by 6. add 2 to both sides. not this one change the direction of the inequality. change the inequality to ≤.
