Graphs are very important for recording the results of any experiments. Now the students are drawing graphs in their exercise books. First, they are giving the graphs a little. Then they are drawing the axes and putting the independent variable along the bottom of the graph paper (the horizontal axis). The other variable depends on this one and the students are drawing it up the side of the paper (the vertical axis). It is also called the dependent variable. The origin of the graph is usually the point (0,0).

Matrix А is a square nonsingular matrix of the third order, all elements of which are non-zero. The greater number of zeros which  A can have, is equal to …

When the boat moves on the surface of the water the resistance force of the environment F is directly proportional to the speed v (, where  - coefficient of proportionality). At the moment of the engine shutdown the outboard motorboat is moving at a speed of 224 m/min., and 3 min. later it’s speed is equal to 112 m/min. 9 min. after the engine shutdown the outboard motorboat will be moving at a speed of ______ m/min.

Captain Silver buried treasure on a desert island. There are only two palms on this island: a small one and a big one. They are situated at a distance of 400 m from each other. Silver told the rest of the pirates that the treasure is located at a three times greater distance from the small palm than from the big one. If L is the largest possible length of the ditch the pirates have to dig to find the treasure, then the value of the expression  is equal to…
