The displacement from equilibrium of a weight oscillating on the end of a spring is given by y = 1.93 -0.220
cos(4.90)
where y is the displacement (in feet) and is the time (in seconds). Use a graphing utility to graph the displacement function for Osts 10. Find the time beyond which the distance between the
weight and equilibrium does not exceed 0.9 ft. (Round your answer to 2 decimal places.)

In the diagram, the ratio of ab to ae is (1/2) . what is the ratio of the length of to the length of ?

Consider the function f(x)=-5x+3 what is f(-2)

Which statements are true? check all that apply. the line x = 0 is perpendicular to the line y = –3. all lines that are parallel to the y-axis are vertical lines. all lines that are perpendicular to the x-axis have a slope of 0. the equation of the line parallel to the x-axis that passes through the point (2, –6) is x = 2. the equation of the line perpendicular to the y-axis that passes through the point (–5, 1) is y = 1.
