11.Suppose that during a controlled experiment, the temperature in a test tube attime t is rising at a rate of 6t^2+2 degrees centigrade per minute. If the initialtemperature is 20°C, what is the temperature in the test tube after 10 minutes?
The increase in carbon dioxide (CO2) in the atmosphere is a major cause of global warming. Using data obtained by Charles David Keeling, professor at Scripps Institution of Oceanography, the average amount of CO2 in the atmosphere from 1958 through 2016 is approximated by A(t) = 0.012414t2 + 0.7485t + 313.9 (1 ≤ t ≤ 59) where A(t) is measured in parts per million volume (ppmv) and t in years, with t = 1 corresponding to 1958.† Find the average rate of increase of the average amount of CO2 in the atmosphere from 1958 through 2016. (Round your answer to two decimal places.)
A jar contains 100 mL of a certain substance which, when heated to tt degrees Celsius contains E(t) = 2.3 t^2 - 4.5E(t)=2.3t2−4.5 Joules of thermal energy. Assuming that the thermometer measuring the temperature of the substance is accurate to within 0.20.2 degrees Celsius. Find \displaystyle \frac{dE}{dt}dtdE first, and then use differentials to estimate the possible error in the calculated thermal energy at t = 60t=60 degrees.

In an effort to make the distribution of income more nearly equal, the government of a country passes a tax law that changes the Lorenz curve from y = 0.98x2.1for one year to y = 0.32x2 + 0.68x for the next year. Find the Gini coefficient of income for both years. (Round your answers to three decimal places.) after before

When a tap at the base of a storage tank is turned on, water flows out of the tank at the rate of 200 e^-1/5t litres per minute. If the volume of water in the tank at the start is 1000 litres, find how much is left after the tap has been running for 10 minutes. Hint: V will be decreasing, and so dv/dt must be negative
The increase in carbon dioxide (CO2) in the atmosphere is a major cause of global warming. Using data obtained by Charles David Keeling, professor at Scripps Institution of Oceanography, the average amount of CO2 in the atmosphere from 1958 through 2010 is approximated by A(t) = 0.012313t2 + 0.7545t + 313.9 (1 ≤ t ≤ 53) where A(t) is measured in parts per million volume (ppmv) and t in years, with t = 1 corresponding to 1958.† Find the average amount of CO2 in the atmosphere from 1958 through 2010.

Can you find the amount of salt A in the tank at any time t?
Suppose that we are interested in the amount of salt (in kg) at a certain moment in time, denoted by A(t), in a well-mixed, infinitely large tank with 400-L of water initially. Further, suppose we have set-up the experiment such that a salt solution containing 16 kg/L flows into the tank at a rate of 9 L/sec. If we allow the solution to flow out at 6 L/sec, then what is the volume of water in the tank at time t? V(t) = _____? ( (DO NOT use commas in your answer) Construct a model for the change of salt in the tank at time t. [To ensure you are marked correct, please use A to represent the amount of salt in the tank at time t not A(t)]. dA/dot=_________?
