Use colored counters to answer the question. Typically, black counters represent a profit or a positive number, while red counters represent a loss or a negative number. Here, use white in place of red, that is, consider a white counter to mean what a red counter would in the typical case.How many different-appearing rows of counters can be made using 4 counters each time? Each counter has a black side and a red side. Two possibilities are shown here (with red being represented by white).

Solve the problem.A boy is flying a model airplane while standing on a straight line. The plane, at the end of a twenty-five foot wire, flies in circles around the boy. The directed distance of the plane from the straight line is found to be d = 25 cos where d is measured in feet and t is the time in seconds. If d > 0, the plane is in front of the boy; if d < 0, the plane is behind him. What is the amplitude? What is the period? Graph d over two periods beginning at t = 0.
