Suppose that in the country of Sudland, when the yearly rate of economic growth fell from 3.0% to 1.5%, the yearly rate of increase in airborne pollutants fell from 6% to 5%. What is the average slope of a nonlinear curve between these points using the arc method? The average slope is
Nesto hypermarket sells three brands (A, B, and C) of laptop computers. The monthly sales of the three brands are: Brand A = 15 units; Brand B = 9 units and Brand C = 12 units. The unit price of brand A is R.O. 300; brand B is R.O. 280 and brand C is R.O. 200. The cost to the Stores is 280 R.O. for brand A; 260 R.O. for brand B, and 180 R.O for brand C. Let Q = ; P =; and C = Using the above matrices, calculate the following: Calculate total revenue Calculate total cost Calculate the monthly profit
Given the function f(x) = ln (x+1), x>0 In applying mathematical methods to economics/business problems, we use a broad menu of functions for the purpose of accurately specifying the properties of the economic variables in question. Find an example that you can use the above function to describe certain economic or business activity.

A first year student estimated a linear consumption function and found out that Ct = 200 + 0.65Yc + 0.25 Ct t-1. Give economic interpretation of the above result, clearly explaining the meaning of the intercept, variables and the coefficients.
For each of the following scenarios, indicate whether the relationship between the two variables is positive or negative, as well as which line on the previous graph has a slope that reflects this type of relationship. Hint: The X-axis and Y-axis on the graph are not labeled intentionally. You need to substitute the variables from each scenario for the horizontal and vertical axis. For example, in the first scenario, X-axis should be labeled “ ice-cream" and Y-axis should be labeled "The temperature". Relationship options: positive, negative Line options: A, B, C, D True or False: Line D has a slope of infinity.

Marketing surveys conducted by the sales manager for a company determined that 3,000 power drills could be sold for $60 each, but 4,000 drills could be sold for $50 each. (a) If the two data points were plotted on a coordinate system with the number of drills sold on the horizontal axis and the price of each drill on the vertical axis, what is the slope of the line between the two points? (b) Write a sentence that explains the result in part (a) in the context of this problem. For every additional drill sold, the price per drill (in cents) decreases by cent(s). (c) Assuming the trend in part (a) continues, how many drills can be sold for $56? drills
