Oil leaked from a tank at a rate of r(t) liters per hour. Values of the rate at 2-hour intervals are given in the table below.
time (hours)r(t) (liters per hour)
| 0 | 2 | 4 | 6 | 8 | 10 | 12 |
| 8.7 | 7.6 | 6.8 | 6.2 | 5.7 | 5.3 | 5.0 |
(a) Use a Left Hand Sum with n=3 subdivisions to give an
approximation on the total amount of oil lost over the time
interval from t=0 to t=12 hours. Include units in your
answer.
(b) Use the average of a Left Hand Sum and Right Hand Sum with n=6
subdivisions to give an approximation on the total amount of oil
lost over the time interval from t=0 to t=12 hours. Include units
in your answer.

A massive oil spill in the gulf unleashes approximately 20,311
barrels of oil into the Gulf each hour. This creates an expanding
circular layer of oil on the water’s surface about 1/16 inches
thick with the center being the source of the spill. Letting R(t)
represent the radius (in miles) t hours after 6:00pm, the growing
radius of this oil spill can be modeled by the formula: R(t)=1/2
?(t+1)
1.) What time did this spill start? (When was the radius...

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.
_____ Typical rating curves for weirs are concave upward.
Typical rating curves for orifices are concave downward.
