A horizontally moving tennis ball barely clears the net, a distance y above the surface of the court. To land within the tennis court the ball must not be moving too fast. To remain within the court's border, a horizontal distance d from the bottom of the net, Find the ball's maximum speed over the net.
Express your answer in terms of the variables d, y, and appropriate constants.

According to the tide table below what time of day will the highest tide occur?

An object moves from position +34m to the position -15m in 15 seconds. what is the total displacement? what is the total velocity?

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.)
