1. A seal dives into water from a shore 6 feet high. Its path is modeled by the equation y= (1/4)x^2 -20x+6 where x is the seal's distance from land and y is the seal's depth. How many feet does the seal travel horizontally before it swims out of the water? Write your answer in radical form.

Snell's Law at its heart is a minimization problem. Light takes
the path which takes the least time. The classic comparison is a
lifeguard at a beach who needs to pick the correct path to get to a
struggling swimmer in the least time. Assume the lifeguard can run
at 2 meters/second on land, but can only swim at 1
meter/second.
Have the lifeguard start at (0,5). The shoreline runs along the
x-axis. The swimmer who needs help will have...

Part I. Indicate whether true or false (T or F).
____ Storm water detention ponds typically are designed to
regulate the outflow peak rate at or below a single target value,
such as the pre-development (pre-land use change) peak runoff rate
for a specified return period event. Detention storage alters the
peak but not the volume of the outflow hydrograph.
