Sales performance. A chain that specializes in healthy and organic food would like to compare the sales performance of two of its primary stores in the state of Massachusetts. These stores are both in urban, residential areas with similar demographics. A comparison of the weekly sales randomly sampled over a period of nearly two years for these two stores yields the following information: Does it appear that one store sells more on average than the other store?
Part B Using this relationship, what is the position of the bowling ball at times t=4.0st=4.0s and t=8.0st=8.0s? Part A The position of a bowling ball rolling on a smooth floor as a function of time t is given by: X(t) = vot+20, where vo = 2.5 m/s and 20 = -5.0 m. The polynomial relationship between position and time for the bowling ball is View Available Hint(s) O cubic inverse exponential quadratic linear Submit Previous Answers Correct A linear function is of the form y=mx+b where m and b are constants. Note that for a linear function written in this form, that is the highest power of the independent variable in the polynomial expression for the dependent variable y is 1. In a linear function the constant m is called the slope, and the constant b is called the y-intercept.
