An oil tanker has hit a sand bar and ripped a hole in the hull of the ship. Oil has begun leaking from the tanker. The oil is leaking from the ship forming a circle around it. The radius of the circle is increasing at a rate of 2.3 feet per hour. Please assist the Wild Life Federation with the following calculations. Thank you in advance for your assistance. (Round all answers to the nearest tenths place unless otherwise specified, use the π button on your calculator for calculations.) 1) A) Write the radius of the circle as a function of time. Use t as the symbol to represent time (you will need to use the information found in the news clip above.) B) What is the radius of the circle after 2 hours? C) What is the radius of the circle after 2.5 hours? D) If the oil tanker is 250 yards from shore, when will the oil first reach the shoreline? (Remember to convert to feet) 2) Write the area of the circle as a function of the radius. Use the symbol r to represent the radius. 3) A) Using the functions found in questions 1 and 2, write a function that represents area as a function of time. B) What is the area of the circle after 2 hours? C) What is the area of the circle after 2.5 hours? D) What is the area of the circle after 3 hours? E) What is the area of the circle after 3.5 hours? Math 171 Unit 1 Lab 4) Compute the average rate of change per hour for the area from 2 to 2.5 hours. 5) Compute the average rate of change per hour for the area from 3 to 3.5 hours. 6) Based upon the results found in questions 4 and 5 what is happening to the average rate of change of the area of the circle as time passes? (Increasing, Decreasing, Constant?) 7) If the tanker is 250 yards from the shore, how long will it be until 8 miles of shoreline is contaminated with oil? Round to the nearest number of days. (For the benefit of this problem, the shore is straight and if you were to draw a line perpendicular to the shore 250 yards you would find the boat, the spread will be 4 miles to either side of the ship, refer to the diagram below. Hint 1mi=5280 ft.) A) Use the figure below and find the length of the radius in feet. B) Using your formula from problem 1A, find the time in hours. C) The original question asks for the time measured in days. Convert your answer from 7B to days, rounding to the nearest number of days. Radius Radius 250 yds 4 miles 4 miles

1. An oil tanker belonging to Oil Finders, Inc. runs aground and causes a massive oil spill that damages several miles of the Texas coastline. As a result, several public beaches are rendered unusable to the public. Riker and Picard are avid surfers who like to hit the waves as often as they can. Because of the oil spill, they will not be able to surf for at least six months. They file suit against Oil Finders, Inc. for nuisance....

A VLCC (very large crude carrier) is a large oil tanker that, when fully loaded, has a mass of 300,000 metric tons. (One metric ton is 1000 kg.) While several miles from port, the tanker is moving at a speed of 12.0 mph when the captain shuts dwn the engines. The tanker continues moving foward, slowed by the drag force of the water. After traweling a distance of 3.00 km the tanker's speed is 4.00 mph. Find the magnitude of...

An oceanic Oil Tanker weighing 63,000 tons with no fuel has 13 separate tanks with dimensions of 110’ x 107’ x 32’. The waterline on the ship has a cross sectional area of 280,000 ft2. The ship can submerge a maximum of 15 feet due to the weight in the tanks, and the cross sectional area of the waterline will remain the same area. What is the maximum number of gallons of Kerosene (S.G. = .87) that the ship can...

It is difficult to extinguish a fire on a crude oil tanker, because each liter of crude oil releases 2.80×107 J of energy when burned. To illustrate this difficulty, calculate the number of liters of water that must be expended to absorb the energy released by burning 1.00 L of crude oil, if the water has its temperature raised from 24.5 °C to 100 °C , it boils, and the resulting steam is raised to 325 °C. Use 4186 J/(kg·°C)...

The Greek shipping company Ionia Management managed a 600-foot oil tanker that delivered oil to ports along the eastern seaboard of the United States. During these deliveries, Ionia's engine room crew, at the direction of their ship supervisors, regularly dumped oily waste into the ocean. To conceal the wrongdoing, the ship's crew falsified entries in its oil record book and lied to Coast Guard officials regarding the waste. The top executives and officials at Ionia did not know that employees...

A hole was shot in a pipeline using a high-powered rifle. The discharge rate of oil from the pipeline was estimated at 140 gal/min. Estimate the hole diameter (in inches) assuming a pipeline pressure of 500 psig (72,000 lbf/ft2), discharge coefficient is 0.61, and the density of water is 62.4 lbm/ft3. The specific gravity for the oil is 0.93.
