The motion of a weight that hangs from a spring is represented by the equation h=5sin(3pi/4t). it models the weights height, h, in inches above or below yhe rest position as a function of the first of time, t, in seconds. approximately when will the object be 4 inches below the rest position? round to the nearest hundredth if necessary. a. 0 seconds
b. 0.29 seconds
c. 0.39 seconds
d. 1.95 seconds

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.

step-by-step explanation:

answer: h=5.6 i don't really know how to put into words, so i though i would let you do that. i hope i was able to some

step-by-step explanation:

18 = 6(h)+1/2

18 = 6h+1/2

18-1 = 6h/2

17 = 3h

17/3 = h

h = 5.6
