Akid's pool had a small opening though which water leaked out sometimes. water was poured into the pool from time to time. the graph below shows the amount of water in the pool (y), in gallons, at a certain time (x), in hours:
graph of first line going through ordered pairs 0, 40 and 2, 10. graph of second line going through ordered pairs 2, 10 and 4, 10. graph of third line going through ordered pairs 4, 10 and 7, 50.
which of the following statements best describes the amount of water in the pool?
it is increasing during the time interval 4 < x < 7 hours.
it is increasing during the time interval 10 < x < 50 hours.
it is decreasing during the time interval 4 < x < 7 hours.
it is decreasing during the time interval 10 < x < 50 hours.

The magnitude, m, of an earthquake is defined to be m=log l/s, where i is the intensity of the earthquake (measured by the amplitude of the seismograph wave) and s is the intensity of a “standard” earthquake, which is barely detectable. what is the magnitude of an earthquake that is 1,000 times more intense than a standard earthquake? use a calculator. round your answer to the nearest tenth.

Talia took the bus from her home to the bank and then walked back to her home along the same route. the bus traveled at an average speed of 40 km/h and she walked at an average speed of 5 km/h. to determine the time, x, that it took talia to walk home, she used the equation 40(0.9 – x) = 5x. the time of trip 2 is hours. the distance of trip 1 is km.
