Fishing boats use sonar to locate schools of fish. What characteristic of sound is most important for this application of sonar? Sound waves reflect off some surfaces
Sound waves diffract around corners
Sound waves interfere when they overlap
Sound waves spread out from a source

What is the rate of change in a objects position?

True or false graphs must include scales that increase by the same amount

The temperature at a point (x, y) is t(x, y), measured in degrees celsius. a bug crawls so that its position after t seconds is given by x = 6 + t , y = 8 + 1 3 t, where x and y are measured in centimeters. the temperature function satisfies tx(3, 9) = 5 and ty(3, 9) = 4. how fast is the temperature rising on the bug's path after 3 seconds? (round your answer to two decimal places.)
