A weight attached to a spring is pulled down 5 inches below the equilibrium position. Assuming that the frequency of the system is 6/pi cycles per second, determine a trigonometric model that gives the position of the weight at time t seconds. a) y = –5 cos 12t b) y = 5 cos 12t c) y = –5 cos 6t d) y = 5π cos 6t

this is the formula: v = the value of investment at the end of the time period

p = the principal amount (the initial amount invested)

r = the annual interest rate

n = the annual frequency of compounding (how many times a year interest is added)

t = the number of years the money is invested

^ means raise to the power of

( - 4 , -7 )

all the lines must parallel  

step-by-step explanation:

coordinates of c = ( - 1 , 2 )

3 units left = ( -4 , 2 )

9 units down = ( - 4 , 11 )
