A larger and brand new CT scanner can run as high as $2.5 million. Prices are slightly higher for MRI machines, running up to about $3 million for a new machine.
1. constant of proportionality-the constant value of the ratio of two proportional quantities x and y; usually written y = kx, where k is the factor of proportionality. factor of proportionality.
Proportional quantities can be described by the equation y = k x, where k is a constant ratio. Step 2) we can tell that the relationship is directly proportional by looking at the graph. The graph is a straight line and it passes through the origin. So, the relationship is directly proportional. First, create a chart. Use points from the graph, such as (2, 20), (4, 40), (6, 60), (8, 80) and (10, 100)..
