Colin wants to frame a photograph that measures 8 inches by 10 inches. The frame will be the same width on each side and will make the area of the photograph plus the frame one and one half times the area of the original photograph. Find the width of the frame. Wendy throws an object upwards from the top of a building. It follows a path modelled by the quadratic function: h(t) = −4.9t² + 24.5t + 160. Between what times is the object at a height greater than 180 m?
