Bob had a satellite dish installed for his LCD television. The depth (d) of the satellite dish can be modelled by the relation d = (-0.006w) (w – 60), where (w) represents the width, in centimetres. Find the depth of the dish when the width is 40 cm. The depth of the dish is:

The shape of a mountain can be modelled by the factored equation y = -0.05x(x – 30), where y represents the height of the mountain and x represents the horizontal distance. Both measures are in metres. The width of the mountain is the distance from one x-intercept to the other. What is the width of the mountain (including units)? Use the “Desmos” graphing calculator to help determine the width:www.desmos.com The width of the mountain is
