An object moves in simple harmonic motion with period 8 seconds and amplitude 5 cm. At time t = 0 seconds, its displacement d from rest is -5 cm, and initially it moves in a positive direction.
Give the equation modeling the displacement d as a function of time t.

Four individuals pool money together to start a new business and agree to split the profits equally. n invests $6,000, x invests $2,000, y invests $8,000 and z invests $4,000. if the profits for the first month were $100,000, y receives than if the profits were divided in proportion to how much they invested.
