The amount of freight transported by rail in the u. s was about 580 billion ton-miles in 1960 and has been increasing at a rate of 2.32% per year since then. a. write a function representing the amount of freight, in billions of ton-miles, transported annually. ( 1960 = year 0 )

b. graph the function

c. in what year would you predict that the number of ton-miles would have exceeded or would exceed 1 trillion (1,000 billion)?​

Tommy buys a sweater that is on sale for 40% off the original price. the expression p -0.4p can be used to find the sale price of the sweater, where p is the original price of the sweater. if the original price of the sweater is 50, what is the sale price?

In the picture below, line pq is parallel to line rs, and the lines are cut by a transversal, line tu. the transversal is not perpendicular to the parallel lines. note: figure is not drawn to scale. which of the following are congruent angles?

:i need some real : a store sells shirts to the public at one pricing scale and wholesale at another pricing scale. the tables below describe the cost, y, of x shirts. (after tables) how do the slopes of the lines created by each table compare? the slope of the public table is 3/4 of the slope of the wholesale table.the slope of the wholesale table is 3/4 of the slope of the public table.the slope of the public table is 12 times greater than the slope of the wholesale table.the slope of the wholesale table is 12 times greater than the slope of the public table.
