367.You are trying to thaw some vegetables that are at a temperature of 1°F. To thaw vegetables safely, you must put them in the refrigerator, which has an ambient temperature of 44°F. You check on your vegetables 2 hours after putting them in the refrigerator to find that they are now 12°F Plot the resulting temperature curve and use it to determine when the vegetables reach 33 °F.

- For the following exercises, solve the application problem. 48.The volume V of an ideal gas varies directly with thetemperature T and inversely with the pressure P.A cylinder contains oxygen at a temperature of310 degrees K and a pressure of 18 atmospheres in avolume of 120 liters. Find the pressure if the volumeis decreased to 100 liters and the temperature isincreased to 320 degrees K.arrow_forwardFind the intensity of light at a depth of 12 meter if I0=14 and k=0.7. Round to two decimals.arrow_forwardRefer to the previous exercise. Suppose the lightmeter on a camera indicates an EI of 2 , and thedesired exposure time is 16 seconds. What should thef-stop setting be?arrow_forward

(Simplify your answer.) %3Darrow_forward10) The Hurricane Hunters took the following measurements from a hurricane over They found that the air pressure and wind speed are related in the following way: y=-1.11x+1140 where x is the air pressure in millibars (kPa) and y is the maximum sustained wind speed in knots (nautical miles per hour). several days as it developed: Air Pressure (kPa) Wind Speed (knots) 924 129 933 110 946 67.3 140 958 86 120 991 41.3 100 1,002 35.7 車 920 910 Air Pressure (kPa) a) What does the y-intercept of this function represent? b) Using the model, what would be the wind speed of a hurricane with an air pressure of 969 kPa? Round your answer to the nearest knot. Wind Speed (knots)arrow_forward
- Ricardo measured the temperature in the morning. The temperature was −6 ºC. The temperature is increasing 1 1/2 ºC every hour. After how many hours will the temparature be at least 2 ºC?arrow_forwardA police car traveling south toward Sioux Falls at 160km/h pursues a truck traveling east away from Sioux Falls, lowa, at 140 km/h (See figure below). 160 km/h Sioux Falls 140 km/h At time t 0, the police car is 40 km north and the truck is 60 km east of Sioux Falls. Calculate the rate at which the distance between the vehicles is changing at t O minutes.arrow_forwardfind r when t = 10 r = 0.07t + 2.27 (2 decimal place)arrow_forward
