An underground cable is going to be laid between points A(-6,23) and B(14, -12).

a) If each unit represents 1 m, what length of cable will be needed? Give your answer to the nearest metre.

b) An access point will be located halfway between the endpoints of the cable. At what coordinates should the access point be built?

A stone is tossed into a pond, creating a circular ripple. The radius of the ripple increases by 12 cm/s.

a) Write an equation that describes the ripple exactly 3 s after the stone lands in the water. Use the origin as the point where the stone lands in the water.

b) A bulrush is located at point (-36, 48). When will the ripple reach the bulrush?
