4. An observation tower is 75 m high. A support wire is attached to the tower 20 m from the top. If the support wire and the ground form an angle of 46 degrees, what is the
length of the support wire, to the nearest tenth?

The graph shows the distance y, in inches, a pendulum moves to the right (positive displacement) and to the left (negative displacement), for a given number of seconds x. how many seconds are required for the pendulum to move from its resting position and return? enter your answer in the box.

Which equation represents a line that is parallel to the line whose equation is 3x-2y=7( show all work)

What are the solutions of the system? solve by graphing. y = x^2 + 3x + 2 y = 2x + 2
