restaurant chain ’s management wants to determine the best locations in which to expand their restaurant business. So far the most successful locations have been near college campuses. This opinion is based on the positive numbers that quarterly sales (y) reflect and the size of the student population (x). Management ’s mindset is that over all‚ the restaurants that are within close proximity to college campuses with large student bodies generate more sales than restaurants located near campuses with

Abstract This purpose of this experiment was to observe the relationship between centripetal acceleration‚ centripetal force‚ and a mass M. In this experiment we used a circular motion apparatus that had a plumb bob attached to a metal shaft (that connected the plumb bob to the vertical shaft) and spring. We found the centripetal force from the spring when it was in circular motion. We hung masses off a pulley system that was attached to the plumb bob until the plumb bob was perpendicular to the

equals the absolute value of the slope. The MRTS tells us how much of one input a firm can sacrifice while still maintaining a certain output level. The MRTS is also equal to the ratio of Marginal Productivity of Labor (MPL): Marginal Productivity of Capital (MPK). The mathematical form of how Labor (L) can be substituted for Capital (K) in production is given by: MRTS (L for K)= -dK/dL = MPL/MPK For Example: When going from point B to A in Figure 9.1‚ the Slope = (8 units of Capital)/(-6 units
