question 144

Multiple Choice

The function graphed is of the form y $$y = a \sin b x \text { or } y = a \cos b x , \text { where } b > 0$$ Determine the equation of the graph.
-A weight attached to a spring is pulled down 3 inches below the equilibrium position. Assuming that the frequency of the system is $\frac { 5 } { \pi }$ cycles per second, determine a trigonometric model that gives the position of the weight at time $t$ second.

• A) \(y = 3 \cos 10 t\)
• B) \(y = 3 \cos 5 t\)
• C) \(y = - 3 \cos 5 t\)
• D) \(y = - 3 \cos 10 t\)
